The Nice Smart SU7-03 is an RFID card-access door lock designed for hotel properties, serviced apartments, and commercial facilities requiring centralized guest access management. Unlike multi-biometric residential models, the SU7-03 operates exclusively through 13.56MHz IC cards with AES encryption, supporting a capacity of up to 500 registered card profiles including master cards, floor cards, building cards, and individual guest cards for hospitality hierarchy management. The lock body uses aluminium alloy and ABS composite housing with a double bolt mortise mechanism for forced-entry resistance. Power comes from 4x AA batteries providing approximately 10,000 lock/unlock cycles with low-battery LED and audible alerts, plus USB emergency power-in for access during battery depletion. Connectivity via TTLock and Tuya IoT platforms over Bluetooth for remote access log monitoring, card authorization management, and lock status reporting from a centralized hotel front desk dashboard. Optional Wi-Fi and NFC modules available. Working temperature range of -20°C to 60°C. IP67 water and dust resistance rated. Compatible with wood and metal doors. Available in gold, champagne, black, and silver finishes. Dimensions: 370 × 25 × 80 mm. CE, FCC, and RoHS certified. OEM branding including logo engraving, custom packaging, and firmware configuration available. MOQ from 20 units with 7-day lead time on standard orders.
The SU7-03 uses 13.56MHz IC cards (Mifare standard) with AES encryption. The system supports master cards, floor-level cards, building cards, individual guest cards, and emergency override cards for hotel property management.

The SU7-03 fits standard door preparations with 35-65mm thickness compatibility. For fire-rated doors, verify that cutout specifications meet local fire code requirements.
Mechanical key backup allows manual access at all times. The USB emergency power port on the exterior panel allows temporary power from a portable battery to unlock electronically. Low-battery warnings activate well before full depletion.
