ABSTRACT
From the user’s point of view, the NFC transactions become popular as they limit the time needed for a user to do a transaction. Conversely, Alimi et al. (2013) studied the use of NFC transactions for the merchant side, proposing “different architectures in order to use a mobile phone as a point of sale.” For security reasons, the users are biometrically authenticated through the use of the touch screen on their smart phones.
