Card readers are based around a pn532 chipset reader, configured to HSU (High Speed UART) mode. This should allow us to read the UID field from block zero of almost all 13.56MHz RFID cards,rings,bands,fobs.

Elechouse V3 modules (genuine, red boards). Need a good +5V Vcc supply to be able to energise bank cards., use a DC/DC boost converter on long cable runs. | * Elechouse V3 modules (genuine, red boards).

Fake Elechouse V3 modules. Don't read very well at all except for very simple fobs with limited power draw. These can be identified by not having the word 'Elechouse' in italics, or having a full stop after the "NFC MODULE V3" label. | * Fake Elechouse V3 modules.

The Cisa solenoid latch on the back door required very gentle adjustments, and was not really suited to a double-leaf door installation. | ||
