ACR122U is a 13.56 MHz PC/SC (CCID) reader, not HID. Browsers can't talk to PC/SC devices directly, so the kiosk JS can't see ACR122U taps the way it sees a USB-HID reader. This daemon bridges the gap: - Polls the ACR122U via pyscard - Reads UID via the standard ACS GET_UID APDU (FF CA 00 00 00) - Types UID + Enter into the focused window using pyautogui - Debounces re-reads of the same card (2s window) Output format matches FusionClockNfcKiosk._normalize_uid() expectations: colon-separated uppercase hex (04:10:5B:CA:FD:22:90 + Enter). The kiosk JS already has a keyboard-wedge listener (v19.0.3.2.0+), so no server-side or kiosk-side changes needed — wedge.py's keystrokes route through the same handleTap() path as a USB-HID reader, preserving photo verification + penalty + activity log. Setup docs include macOS, Windows, Linux instructions plus launchd/Task Scheduler/systemd snippets for running as a service. Strategic value: with this, ACR122U deployments support UA-Pockets (13.56 MHz DESFire EV3) for single-card door+clock setups in the premium tier of the standard product kit. The 125 kHz EM4100 USB-C HID reader remains the default tier.
