Abstract: A method is for processing transmission errors during contactless communication of information between a device and a reader. The information may be transmitted in the form of frames sent to a send/receive module of the reader in contactless coupling with the device and controlled by a control module coupled to the send/receive module. The information may be extracted from the frames within the send/receive module so as to be delivered to the control module. The method may include a detection of transmission errors that are to be ignored.
