As a security measure you will be asked to have your photo taken and for a scan of one finger. Once a finger scan has been taken, the scan will be used to verify your registration details at the start of each test session or after returning from the washroom.
We securely store finger scans as a binary code (a series of numbers). No image of your finger scan is stored and the data is kept securely in accordance with privacy legislation. Please see here for details.
