Abstract
A method for processing transaction data, implemented by a communications terminal having a touch screen. The method includes: detecting a necessity of entering a piece of personal identification data; transmitting to a card reader connected to the communications terminal a request for supporting a display of a virtual keypad, the request comprising a piece of data representing a passage of the communications terminal from a “master” mode to a “slave” mode of operation, the slave mode leading to implementation of the method for processing transaction data under the exclusive control of the card reader; of entry, by the user on the virtual keypad, of the piece of personal identification data; and receiving, from the card reader, the piece of personal identification data.
