Abstract: The invention relates to a method for acquiring data from a user at the time of a card payment made using a payment terminal, in which: a data acquisition request is displayed (26) on a screen of the payment terminal following the completion of the payment transaction; the data is acquired (28) by the payment terminal; the acquired data is validated (30) in the terminal; and, if the data is valid, the data is transmitted (34 or 37) by the payment terminal to a consolidation server and a card removal authorization message is displayed (36) on the screen of the terminal. The acquisition includes a maximum period parameter and the data is considered to be invalid if acquired after said maximum period and/or if acquired when the chip card is not in the payment terminal.
