Occupational Reading Assessment

Smart cards are grouped into two major classes: contact cards and "contactless" cards. Contact cards have gold$-$plated contacts that connect directly with the read$/$write heads of a smart card reade when the card is inserted into the device. Contactless cards contain an embedded antenna and work when the card is waved within the magnetic field of a card reader or terminal. Contactless cards are better suited for environments where quick interaction between the card and reader is required, such as high$-$volume physical access. Smart cards can be configured to include both contactand contactless capabilities, but two separate interfaces are needed, because standards for the technologies are very different.
