Smart Booking & Access Control Terminal with NFC

Smart booking terminal with display and NFC access card

Droid Technologies designed and developed a smart booking and access control terminal for remote reservation and management of shared spaces and services, including banks, restaurants, coworking spaces, meeting rooms, and commercial facilities.

The device enables users to book and manage time slots remotely, while the integrated display shows availability, reservations, and system status.

The platform is based on a Nordic nRF52840 and ESP32-S3, providing Bluetooth Low Energy (BLE) and Wi-Fi connectivity. It also supports Ethernet with Power over Ethernet (PoE), simplifying installation by combining power and network connectivity through a single cable.

Additional interfaces include NFC, 125–128 kHz RFID, and USB-C, enabling integration with access control systems, cloud platforms, mobile applications, and external infrastructure.

Droid Technologies delivered hardware design, PCB development, embedded firmware, Wi-Fi/BLE integration, NFC/RFID implementation, PoE integration, display integration, networking, and complete system testing.
