Answer:
The TES 5557 serves as a front-desk encoder and reader that writes guest permissions and staff clearances to 125 kHz cards through host management software over USB.
Unlike door-mounted reader hardware, the TES 5557 is a desktop card connector and programmer engineered for front-desk access administration:
- Card Issuance: Transmits configuration data and room keys to 125 kHz proximity cards based on commands received from the hotel lock software.
- USB Interfacing: Communicates directly with the client terminal over a USB connection for continuous read/write capability.
- Enclosure Build: Built with a compact plastic casing measuring 10 x 14.5 x 3 mm for space-conscious integration at reception counters.
