EM-format Card Calculator
Below is a simple calculator to convert raw EM-format card number into site code and card number. It can also convert the site code and card number back to the raw EM-format card number.
This will be useful for security technicians who have an EM card programmer and need an easy way to convert card numbers.
This calculator was created after a request from Charlie Stokes (aka: Pelican)… enjoy!
