Article on a way (or two) on how to perform high value payment (eg. value more then £20/€20/$20) transaction using mobile keyboard as PIN pad.
Comment: Interesting move.
As I understand, using the mobile keyboard as pin pad needs certification by the large payment schemes (eg. EMV) for evry mobile model..
Using a contactless card alike approach for high value transaction I think would lower end user “hurdle” and avoid the certification need.
– Touch mobile at POS-terminal
– Enter card PIN at POS pin pad
