Digital wallet wars heat up as MasterCard customers pay by mobile instead of plastic

MasterPass is a new shopping solution that allows people to make purchases with any device without having to pull out a physical credit card. For in-store scenarios either at the register or in the aisle, MasterPass will support the use of NFC, QR codes, tags and mobile devices used at points of sale. For online purchases, MasterPass provides shoppers a simple check-out process by eliminating the need to enter detailed shipping and card information with every purchase.
