This is was a simple project to read the Honeywell/HID Corporation HID security badges that are used by a lot of businesses. I used this to quickly determine the badge’s ID so that I could get the security department to update the building access settings.
The reader comprises of a ProxPoint Plus reader, initially connected to an Arduino Uno (clone). The prototype circuit used a 2×16 serial enabled LCD panel. I found that the 2 lines were a bit to limiting for displaying all of the pertinent information, so this was changed to a larger 4×20 display.
The circuit is a very simple ‘reference’ design utilizing an Atmel ATmega328P micro-controller, 16MHz oscillaltor, 7805 based 5v power regulator, built on some Veroboard. I then managed to squeeze all of this in to a Hammond Manufacturing 1590BB die cast aluminum enclosure. A spare 12v power supply (from some consumer electronics) was used to provide power.

ProxPoint Plus 6005BGB00 / 6005-320-02 – these can be procured on eBay quite cheaply
