Barclaycard Launches PayTag

"

Barclaycard has launched a stick-on credit card which will allow its 12 million customers the chance to make wave-and-pay purchases from their mobile phone or other item of their choice. The PayTag is a quarter of the size of a traditional credit card and will sit unobtrusively on any mobile handset or other item, and is linked to a customer's traditional credit card account. It will let them make purchases in any "contactless" store, restaurant, and even on public transport.
