You must have spotted at least one QR code by now. If not, then you are a certifiable alien from Mars. QR codes are quite the rage. We have them on everything from food labels to car bumpers. And yes, tattoos too!

Well, if you have just taken off your green space suit and wondering what the hullaballoo is all about, check out our very previous What Are QR Codes? Digitize your World & Back Again. It was an emerging technology then which runs rampant now as observed through the sampling of 7 Great Uses For QR Codes & How To Generate Your Own For Free. QR codes are definitely mainstream now, given a boost up the use of smartphones and intelligent scanning apps that reside in them.

So, here are five more web apps which show us how QR codes have gone conventional.

Send a Wikipedia link as a QR Code

If you have a smartphone, QR codes give you the quickest way of opening a link. Take for instance, if you are a knowledge buff and need to send someone a Wikipedia reference. Use QRpedia to generate a quick mobile-friendly QR code. What’s great about that you might say as any online QR code generator can do that! QRPedia is a language detecting QR code generator. It displays the Wikipedia page in the language of the mobile that is used to scan and read the Wikipedia article. Of course, a Wikipedia article in that particular language should exist in the first place. According to its own entry, it is currently in use at institutions including museums in the United Kingdom, United States and Spain.

Read classic books on a bar code

We know that QR codes digitize any information. Books2Barcodes is a QR code exploiting web service which miniaturizes entire pieces of classical literature into a 2D QR code and makes the book device readable. The current catalog is limited but Books2Barcodes is an ongoing effort to digitize classics of literature this way and make them available across any device that can scan a QR code.

QR codes are being in fact used by book publishers to connect readers to interactive content like videos, graphics, and music.

Text to speech with QR codes

Think up some creative uses of this text to speech service called QR Voice which takes the generated audio file and digitizes the speech information in a QR code. The audio file is stored online and anyone who scans the QR code is taken to the speech’s URL where they can listen to the converted speech. QR Voice uses Google’s translation service and supports a range of spoken languages.

Create notes (with photos) and turn them into QR codes

This is the QR code web app which you could end up using the most. QRnot.es helps you transmit a page (with images if need be) via the compact medium of QR codes. You can create a piece of text under 500 words, give it a headline, and attach an image in JPG, BMP, or PNG format. The QR code generated points to this text file. You can print this code, or download it as GIF so that anyone can scan it and reach the byte of information. QRnot.es seems like a simple application to spread some little pieces of information around.

Link LinkedIn with QR codes

A QR code on a business card looks real cool. Of course, it should point to something useful. How about your LinkedIn profile page – PingTags helps you do just that. PingTags is a beta QR code service which makes your LinkedIn profile available via a click on a QR code reader. The reader is directed to the LinkedIn profile page, and he can also easily contact you thanks to the contact info provided. He need not key in any information. You can also check out how many people scanned your barcode, what links they clicked, and a map showing exactly where they scanned the code.

Unfortunately, from the time I checked out this app to the time of writing this article, something went wrong as the site is in the bout of a temporary glitch.

Alternatively, you can use this simple LinkedIn QR code generator if the glitch remains unresolved. Or use any QR code generator which takes a URL (in this case, your LinkedIn profile URL) and outputs a QR code.

QR codes are neat little ways to transmit information and catch them using a QR friendly mobile phone. What other web apps do you know of that help you use QR codes in our day to day lives? Send in some in our comments section.

class="align-right" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/intro10.jpg" alt="" />Quick response codes, or class="vt-p" href="http://www.makeuseof.com/tag/qr-codes-can-digitize-your-world-and-back-again/">QR codes for short, have been used for a few years now to provide rapid access to URLs, messages or contact information. Marketing and advertising departments love QR codes, as with a simple scan, even more advertising related to their product can be delivered straight to your thumbs.

But why let the big multinationals have all the fun? It’s easy and completely free to generate your very own codes, and these can be used in a myriad of useful or entertaining ways. Of course you’ll need a smartphone with a QR reader to enjoy your own creations.

Creating & Reading Your Own

There are plenty of good, free QR generators out there with some offering more advanced options than others. Between them, the following four manage to cover most bases, including contact cards, URLs, text messages and even access to wireless networks (including security codes):

• class="vt-p" href="http://qrcode.kaywa.com/">Kaywa.com QR Generator
• class="vt-p" href="http://goqr.me/">GoQR.me
• class="vt-p" href="http://zxing.appspot.com/generator/">ZXing Project QR Generator
• class="vt-p" href="http://delivr.com/qr-code-generator">Delivr.com QR Codes

style="text-align: center;"> class="aligncenter" style="border: 1px solid black;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/generators_goqr.jpg" alt="" width="580" height="388" />

In order to read them back you’ll need an app for your chosen device. There’s plenty out there, but at the moment I’m using RedLaser for my class="vt-p" href="http://www.makeuseof.com/tags/iphone">iPhone which works a treat (and is fully class="vt-p" href="http://www.makeuseof.com/tags/android">Android compatible too).

• class="vt-p" href="http://itunes.apple.com/us/app/redlaser/id312720263?mt=8">Download Red Laser for iOS (4.0 required, iPhone, iPod Touch, iPad 2)
• class="vt-p" href="https://market.android.com/details?id=com.ebay.redlaser">Download Red Laser for Android (1.6 + required)

Business Cards

Not exactly original, but important nonetheless. Whilst you should always provide adequate contact information on class="vt-p" href="http://www.makeuseof.com/tag/5-ways-to-create-a-business-card-20/">your business card (email address, website, phone number and so on) a QR code might also be a good idea.

style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/business_card.jpg" alt="" width="580" height="369" />

Your QR code could be used to store all of your contact information in vCard format, so that when it is scanned on a compatible device the option to add a new contact appears. With a scan all of the information stored on your paper business card is transferred to a digital device – effortlessly.

This could also work for posters, and is certainly not limited to just vCard uses.

Classified Ads (Offline)

Selling something locally? Too big for snail mail? For weighty electrical items, cars, hardware and so on QR codes could be used to help sell your item. If you are using an online merchant for the sale (such as class="vt-p" href="http://www.makeuseof.com/tags/ebay-tips/">eBay or AutoTrader) the QR code could be used to link directly to the item’s point of sale.

If you’re simply selling offline and advertising locally a QR code can be used to provide a web link to the manufacturer’s description, which will provide a lot more information than you can fit on a classified advertising card. Simply print out your code and glue it on!

Clothing & Jewellery

QR codes are on everything from rings to scarves to t-shirts these days, and getting your own t-shirt from somewhere like Cafe Press or Spreadshirt is easy. Why not advertise your brand on your back? If you’re a photographer, events organiser or musician (to name but a few) who doesn’t mind being scanned regularly then QR might be an effective tool.

style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/ring_qrcode.jpg" alt="" width="580" height="435" />

You don’t actually need a valid use for QR codes in order to get some clothing or alternative jewellery made up though, and a t-shirt or bracelet that scans might make the perfect gift for the geeky girl or guy in your life.

Forum Avatars

Depending on the forum, a QR code as your avatar can act as a quick way of identifying you. Of course you won’t necessary want this for all forums, but it might help drive traffic to your site or increase your social media outreach with a simple scan.

Award yourself additional points if you can actually get it to look like something.

Starting A Revolution

Okay, so starting a revolution might require more than a scan of your mobile phone, but the ability to embed text, email addresses, URLs and so on within a code mustn’t be overlooked. If you’ve got something to say why not place codes around town and get your message out there? Many who know what QR codes are for will probably scan them out of pure curiosity (I know I would).

style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/street_qrcode.jpg" alt="" width="374" height="500" />

Bus stops, the subway, lamp-posts and even urinals (sorry, but it’s true) are all opportunities for this.

CV/Resume

Will adding a QR code to your next job application land you that dream position? Possibly not, but it might set you apart from the rest of the crowd who simply didn’t think that far ahead. Employers love initiative and the ability to demonstrate understanding, so why not show off your forethought and get a cheeky link to your website in the process?

A must for social media types, programmers and techies alike.

Share This!

This could work pretty well on the street, especially if you’re an artist, street performer or (dare I say it) a graffiti writer. Simply stick a QR code next to your artwork/pitch/throw-up and link to a URL that tweets the scene. For example: “I’m currently in St. James Park, London watching The MakeUseOf Jazz Quartet” with a class="vt-p" href="http://www.makeuseof.com/tag/the-five-best-things-about-google-maps/">Google Maps link.

style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/06/qraffiti.jpg" alt="" width="370" height="500" />

Add your own hashtag to monitor the success of your QR bombing. We could call it QRaffiti!

Conclusion

Remember there’s an endless number of applications for QR codes, especially considering it’s so quick and easy to generate your own! As more people switch on to the smartphone revolution, more people have access to these innovations. If you come up with any great unique uses then be sure to let us know!

Looking for a portable scanner? if you are thinking about the possibility of buying a barcode scan system and you could use some advice on which one to buy, you first need to think about what you want to use it for, which will make the process of researching and buying a scanner a lot easier. Choosing to use a mobile scanner can greatly enhance your technique for dealing with digital material, especially when backing up valuable documentation is of the utmost importance. Rather than making an impulsive purchase, it’s highly recommended to keep in mind the following points.

As is the case with every current and sophisticated hardware device, compact scanners are now less complex and simpler to use. They can answer many items you’ll want to scan, for example, business cards and receipts that have accumulated, documents, and even checks. You won’t believe the speed, and these scanners generate impressively sharp images in a variety of output. At the moment, the retail price of a barcode scan system is certainly worth the expense whether you’ll be using it for pleasure or getting down to business.

One of the most popular qualities of these portable usb scanners is that they’re so user-friendly and convenient wherever and whenever you need them. Every scanner comes furnished with a specialized scanning application which will let you obtain impressive results from pictures and text and then save the files to use in various ways. For instance, with id cards, the system has the ability to separate the ‘snapshot’ of the card, the cardholder’s photo and signature, and all the text of the id card arranged in appropriate data and image fields that can be saved to your choice of software.

Before committing to a barcode scan system please give some thought to the next several pointers: (1) determine what you’ll be using a scanner for; (2) scour the internet for the best scanners for your requirements; (3) compare the technical specifications of each scanner; (4) be sure that the manufacturer has a good name and read reviews by customers of the scanner; (5) verify delivery rates and refund or exchange practices.

To save some money at a brick-and-mortar store, you might turn to clipping coupons. But in this day and age, you probably do a lot of your shopping online, especially as Amazon.com offers just about everything you might need to purchase, from books to electronics to groceries. On top of that, it has its own form of coupon: the promotional code.

There’s no need to cut with a pair of scissors along the dotted line anymore. All you have to do is copy and paste a promotional code at checkout to easily save some money. But where do you find these promotional codes? Not in the Sunday newspaper, but on the internet, of course!

Check out these sites that provide free Amazon promotional codes, and you’ll be on your way to saving some cash.

TopHotDeal.com

TopHotDeal.com’s Amazon Discount Finder is updated with lists of Amazon promotional codes for each month. It also includes a matrix at the top that lets you easily browse Amazon’s products by how much percent off you can buy them for.

Lastly, it includes “coupon books.” If you click onto any Amazon product from one of TopHotDeal’s coupon books and add it to your cart, you’ll receive a discount on that product.

DaddyODeals.com

DaddyODeals.com maintains lists of Amazon deals and promotional codes for the current month in a stickied thread in the Hot Online Deals section of their forums.

For this month you’ll notice a topic called “Amazon Promotional Codes, Coupons and Deals for July 2010″ near the top. Click it and you’ll find a series of posts with links to Amazon pages with promotional codes, discounts, and sales.

DealCoupon.com

DealCoupon.com has a simple list of current Amazon promotional codes with expiration dates.

Whereas most other sites like this rely on user-submitted promotional codes, DealCoupon seems to have an editorial staff who test out the coupons before posting them, which results in coupons that work a lot more reliably.

CurrentCodes.com

CurrentCodes.com provides a list of current Amazon promotional codes with expiration dates. Below them you’ll also find a list of other current discount offers on Amazon.

CurrentCodes is definitely one of the most straightforward sources for promotional codes and other deals that will save you money shopping on Amazon.

RetailMeNot.com

RetailMeNot.com is one of the most popular sources for promotional codes for nearly every shopping site out there, so it’s certainly no surprise that it offers a list of user-submitted Amazon promotional codes.

Because they’re user-submitted, they aren’t guaranteed to work (and you’ll certainly encounter some that don’t), but there is a system in place so that users can select whether the promotional code worked or not. You should stick with the codes that have the highest success rates.

Conclusion

These are the best sites for promotional codes specific to Amazon. But if you’re looking for promotional codes for other sites, be sure to check out MakeUseOf’s top 10 sites for promotional codes. MakeUseOf has also previously written about 13 bargain sites, 5 shopping sites, and 5 price comparison sites that will help you save money when shopping online.

Where do you go online to find promotional codes? Do you know of any other good sources for Amazon promotional codes?

Runtime errors in Windows XP usually occur when the program that is being used is having some problems. Likely, when you get a runtime error, the program will automatically shut down and you will lose all unsaved data. This can be very frustrating and can create much stress especially if you were doing something important. For most people, it is imperative that these problems get fixed as soon as possible. So, to help you better understand what these runtime errors are, I will discuss a couple of popular ones and explain how to fix them.

The fist common runtime error is runtime error 424. Error 424 is just one of the many errors that you may come across when using Windows XP operating system software. The message is displayed as “Run-time error ’424′: Object required”, means that the program you are trying to run has experienced a programming error that has resulted in the program’s failure. You will find that this message is often displayed when someone is trying to use Microsoft Access 2000 while attempting to run MS Office Chart Wizard. This takes place when he is still on the data access page.

There are a couple of different ways that you can fix runtime error 424. If you really need to use the Office Chart, then the best thing to do is to uninstall Internet Explorer 6.0 or use a computer that does not have IE 6.0 installed on its hard drive. There are other Internet browsers out there that are just as good as IE, if not better, such as Firefox. Another way to fix this error would be to avoid using the chart wizard at all, if possible. You can do this by right clicking on the chart that you are working on and selecting the “Property Toolbox” that is found in the corresponding menu.

When runtime error 53 appears on your screen, this means that the file you are looking for cannot be found. Error 53 is one of the most common errors that Windows XP users get. Most people get this error when they are trying to use a new software or hardware, after it has been successfully installed into the computer. This is because one of the files that is needed to run the program could either be missing, corrupted or not installed. The unavailability of this file results in the program producing the runtime error, thus, preventing the program from opening.

There are a couple of easy ways that you can fix runtime error 53. One way to fix this error would be to completely uninstall and reinstall the program you are trying to run. You can do this by going into the control panel and selecting add/remove programs and then clicking on the program and clicking remove. You can also fix this error by updating the software or the drivers for the new hardware you are trying to use. If neither of these methods work, contact the company you bought the hardware or software from.

These are only two of the many runtime errors that can occur when using Windows XP. Most runtime errors have easy fixes, but if you run into a problem that you cannot find a solution for, it is time to call in the professionals. Remember, if your computer is under warranty, do not attempt to open it. Doing so could void your warranty. If you find that the computer is not working, send it in for repairs.
