Electronic locks for hotels and access control with NFC and BLE

Designed the PCBs and developed the complete firmware for electronic locks and access control points. The access points and locks can be accessed with RFID cards, mobile App via NFC, mobile App via BLE and online via Hotspot.

Development highlights:

RFID / NFC capabilities to enable user access with cards (MIFARE: 1K, UL, DESFIRE, PLUS), ISO 15693 cards and smartphone (HCE and NFC P2P mode).

Bluetooth Low Energy connectivity to enable user access with a smartphone and remote connectivity via a hotspot.

Low power consumption techniques implemented for battery powered electronic locks.

PCB Antenna design and tuning at 13.56 MHz for RFID and NFC.

Development of a WiFi-BLE Hotspot to communicate with the access points and make them available on-line.

BLE over the air firmware update from smartphone and hotspot.

iOS and Android Apps with BLE and NFC (HCE and P2P) to interact with access points and access cards.
