SnapTag

SnapTag, invented by SpyderLynk, is a 2D mobile barcode alternative similar to a QR code, but that uses an icon or company logo and code ring rather than a square pattern of black dots.[1][2]

Similar to a QR code, SnapTags can be used to take consumers to a brand’s website, but can also facilitate mobile purchases,[3] coupon downloads, free sample requests, video views, promotional entries,[4] Facebook Likes, Pinterest Pins, Twitter Follows, Posts and Tweets.[5] SnapTags offer back-end data mining capabilities.[6]

Use in mobile operating systems

SnapTags can be used in Google's mobile Android operating system[7] and iOS devices (iPhone/iPod/iPad)[8] using The SnapTag Reader App or third party apps that have integrated the SnapTag Reader SDK. SnapTags can also be used by standard camera phones by taking a picture of the SnapTag and texting it to the designated short code or email address.[9][10]
