NFC payment smartwatches are no longer just for buying coffee. With the right configuration, they can also serve as secure access cards for offices, residential buildings, gyms and hotels.

In an access-control scenario, the smartwatch stores an encrypted credential similar to a traditional RFID card. When the user brings the watch near the reader, the door unlocks if the permission is valid. This solution is convenient for employees and guests because it reduces the need to carry separate cards or keys.

At the same time, NFC payment support enables cashless transactions at vending machines, canteens, ticket gates and partner merchants. For companies, this creates a unified ID across physical access and internal payment systems, simplifying management.

From a technical angle, an NFC smartwatch must be compatible with common protocols and provide a secure element to store sensitive data. Battery life and water resistance are important for everyday use.

For hotels, co-working spaces, universities and corporate campuses, a branded NFC access-control smartwatch can enhance user experience, differentiate the service and strengthen loyalty programs.
