Practical guidance
What this means for your property
A fob is a separate physical credential that the resident presents to a compatible reader. NFC describes a close tap interaction, while BLE uses Bluetooth for supported phone-based access at a configured range. Mobile access is a broader category: an app may send an unlock command, or the platform may issue a compatible digital credential.
These methods are not interchangeable. A reader advertising NFC does not by itself establish that it accepts an iPhone or Apple Watch resident key. Compare the exact reader, platform, phone support and enrollment process. A building can also retain an approved physical credential so residents have an alternative to using their phone.
What to confirm before proceeding
Specify the interaction
Ask whether residents tap, use Bluetooth, press an app button or present a wallet credential.
Confirm actual compatibility
Check the chosen reader, software and supported phone or watch together, including any required service plan.
Test everyday use
Demonstrate enrollment, entry and credential removal, and confirm the physical alternative residents can use.
