QR codes for libraries - some thoughts
Aaron Tay · 2010
QR code stands for "quick response", it's basically a 2D barcode that can be used to store urls, text etc. QRcodes can be used to quickly pull data from the physical world into mobile phones which are equipped with free QR code readers (many free ones exist,but Beetagg supports quite a few phones) automatically. Simply scan the QRcode with your phone's camera, and the QRcode reader will pull the information into your phone.
