This is a Gemalto smart card reader, used primarily for secure online banking. It is a handheld device designed for secure authentication using a physical bank card and PIN. The device generates a unique, non-reusable one-time password (OTP) or digital signature to authorize transactions, preventing the user from entering sensitive details on a potentially vulnerable computer keyboard. It is often used by banks like NatWest and RBS for online banking security. The reader has buttons for "Identify", "Respond", and "Sign", facilitating a "challenge-response" security mechanism.
