PN7160TokenProvider¶

PN7160 RFID/NFC token provider returning the token as soon as the tag can be read by the reader

Handwritten Documentation¶

This module provides authentication tokens obtained from RFID cards via the NXP PN7160 NFC chip.

It uses a modified libnfc-nci as external dependency to interface the chip via I²C or SPI, either from user space or via a kernel module.

Configuration of the hardware interface is possible at runtime. The module installs two configuration files:

libnfc-nci_config/libnfc-nci.conf: define NFC options
libnfc-nci_config/libnfc-nxp.conf: choose the hardware interface (kernel module vs. userspace; I²C vs. SPI, …)

The EVerest module can be adjusted in its behaviour as follows:

token_debounce_interval_ms: Publish tokens in minimum intervall of this timespan in order not to flood subscribers.
disable_nfc_rfid: Allows to load the module without actually initializing the hardware.

main: auth_token_provider
