The 1K contactless Smart Card IC S50, which is connected through a coil with a few windings , is embedded in plastic and makes a passive , contactless intelligent card possible in this way. The exchange layer is 2 and 3 compatible with the ISO/IEC14443A standard part. Make contactless data transmission and energy delivery no battery supply necessary.
The 1K is mainly used for buffering as a simple security mechanism divides the data into segments . Therefore, it is ideally suited for massive data transfers in countless different applications, eg Transport tickets , attendance acquisitions , parking tickets , road taxes , etc. Most in closed systems used as a fixed price tickets (eg weekly / monthly tickets) .
