The IOGEAR's GKBSR201 104-Key keyboard with integrated smart card reader is a secure terminal for computer users in hospitals, education, banking or even at home. A Smart Card is the shape of a credit card, however it is embedded with a chip that can process data, and permit access to delegated computer systems. Smart Cards are often programmed with a PIN number to ensure security for both the card holder and the system they want to access. GKBSR201's card reader uses a contact system which is less prone to misaligning your card when it is inserted, eliminating the possibility of it being misread.
