QR codes are becoming a major tool for developers to distribute apps, and for people to share information quickly and easily. QR stands for “Quick Response” and has been in use for years in Japan, but just recently started to catch on in the rest of the world. QR Codes are similar to bar codes, but can encode much more data into a smaller package.
Android users have enjoyed the widespread use of QR Codes in the Android Market and most review sites, where the application’s Market link is encoded, then scanned on the phone to be taken directly to the download page. iPhone users have most of the same benefits, but is not used as commonly.
One of the most useful features is the ability to scan someones QR encoded vCard, and have all their contact information saved directly to your address book. Another time saving feature is being able to generate URLs of your browser’s current tab and scan them on your phone, so you can save time trying to enter the lengthy link on your iPhone or emailing yourself.
QR Codes have been popping up on billboards in Time Square where people can scan them with their phones and get redirected to the company’s website, and on TV commercials linking to the purchase page. Google has even been using its Favorite Places service to promote the use of QR Codes to easily find directions, reviews, and coupons.
There are many paid and free QR Code applications on the App Store, so do a search and try one out to see if it makes life easier. QR Codes are quickly becoming popular, and many phones support this technology.
