Write/read device for communication with transponders, having first coding means and second coding means |
摘要 |
A write/read device (1) for the contactless communication with at least one transponder has a first encoder (4) for coding a data block (DB) in accordance with a first coding method, which first encoder (4) can generate at the most a given number of N coding signals (KI) per data block (DB) in accordance with this first coding method, and has a second encoder (9) for coding a data block (DB) in accordance with a second coding method, which second encoder (9) can generate at the most a given number of M coding signals (KI) per data block (DB) in accordance with this second coding method, and has a selection circuit (10) for the selection between the coding signals (KI) supplied by the first encoder (4) and the coding signals (KI) supplied by the second encoder (9).
