Access control using a numeric keyboard, radio frequency identification (RFID) or combination of both are widely used in the security and access control industry. These types of devices are affordable, robust and simple to install. The RFID itself comes in various shape and sizes containing two sets of information combined to create a unique credential; the facility code of the card and the card ID. This tutorial shows how to use the MonkeyBUS to interpret signals from RFID readers and determine RFID’s facility code and card ID whilst exploring several important aspects of the PIC18F14K50 microcontroller.
