Card Reading Configuration

Users can adjust how the RS3 NFC reader processes and interprets card data:

• Card hold time – determines the duration a card must remain near the reader before being read

• Output format – choose decimal or hexadecimal formats

• Wiegand bit control – modify output length, strip leading/trailing bits, reverse or invert bit order

• FAC control – enable or disable Facility Access Code inclusion

Keyboard Simulation Mode Settings

For applications where the RS3 NFC unit operates as a keyboard input device, you can:

• Define delimiters or specific characters sent before and after each scan

• Ensure smooth integration with software expecting text or ID input sequences

Persistent Storage of Settings

• All configuration changes made through the RS3 NFC Setup app are stored directly in the RS3 unit's flash memory, ensuring that settings remain active even after power cycling or pairing with a new device.

• This persistence makes it well-suited for field deployment and consistent operation across sessions.
