1. A method for contactless communication by a first contactless device, the method comprising:
exchanging, with a second contactless device, frames having a frame format compliant with a contactless communication standard and comprising a start of frame field, an end of frame field, a payload field, and an error check field calculated from the payload field in compliance with the communication standard;
storing modification rules;
modifying, in accordance with the modification rules, a content of at least one frame element of each frame of at least a part of the communication so that the modified content of the at least one frame element is different from a reference content of the at least one frame element compliant with the communication standard, the at least one frame element including the start of frame field, or the end of frame field, or the payload field, or the error check field; and
sending the frames having the modified content to the second contactless device.
