Reader & Terminal to Card CommunicationДЄll cards and readers that follow ISO 7816-3 standards have a standardized set of commands that enable communication for CPU cards. These readers support magnetic stripe-contact and contactless read operations all in one device. Some readers support more than one type of card such as the tri mode insert readers from MagTek.

These methods include RS232 serial ports, USB ports, PCMCIA slots, floppy disk slots, parallel ports, infrared IRDA ports and keyboards and keyboard wedge readers. InterfaceДЄ contact reader is primarily defined by the method of it's interface to a PC. The dominant protocol under the ISO 14443 is MIFARE, followed by the EMV standards. Many contactless readers are designed specifically for Payment, Physical Access Control and Transportation applications. This type of reader works with a radio frequency that communicates when the card comes close to the reader. This interface enables larger data transport without the overhead of anti-collision and wireless breakdown issues that are a result from the card moving in and out of the reader antenna range. The typical PTS Protocol Type Selection (ISO7816-3) negotiated speed can be up to 115 kilo baud. This communication has the advantage of direct coupling to the reader and is considered more secure. The card-to-reader communications is often ISO 7816 T=0 only. This is the most common reader type for applications such as ID and Stored Value.

This type of reader requires a physical connection to the cards, made by inserting the card into the reader.
