PIN (Personal Identification Number) – a secret number that gives you access to the KSD. The PIN code can be 4 to 8 symbols long.
BIO ID – A biometric ID – information that contains data about a person's unique features (ex: fingerprint, voice or retina). The size of the BIO ID is variable; a fingerprint requires about 600 bytes of data, while a voice key-phrase may take up to 30 Kbytes.
Biometric authentication – the process of authenticating a person by analyzing its unique features, using special biometric hardware. Biometric authentication can be carried out by processing one's fingerprint, voice, retina, or other biological characteristics.
