Method for processing transmission errors, in particular noise, during a contactless communication between a card and a reader

A method for processing transmission errors during contactless communication of information between a device and a reader, the method comprising:

• transmitting the information as a plurality of frames to a transceiver module of the reader in contactless coupling with the device and controlled by a control module coupled to the transceiver module;
• extracting the information from the plurality of frames within the transceiver module so as to be delivered to the control module;
• and
• detecting within the transceiver module at least one transmission error to be ignored.

A transceiver device of a reader to be in contactless coupling with a device and controlled by a controller, the transceiver device comprising:

• a receiver configured to receive a plurality of frames from the device;
• a processor configured to extract information from the plurality of frames, and deliver it to the controller;
• and
• a detector configured to detect of at least one transmission error to be ignored.

A reader device comprising:

• a controller;
• a transceiver device cooperating with said controller and configured to be in contactless coupling with a device, said transceiver device comprising
• a receiver configured to receive a plurality of frames from the device,
• a processor configured to extract information from the plurality of frames, and deliver it to the controller, and
• a detector configured to detect of at least one transmission error to be ignored.
