Quick Start Training What is a Smart Card? A smart card is a credit card sized plastic card with an embedded microprocessor and memory and is used for identification, access and to conduct financial transactions Acting like a mini-computer, Smart cards allow money and information to be electronically stored and transferred in a secure, but portable medium

Quick Start Training Smart Card Image Credit card sized plastic card Smart card chip contacts

Quick Start Training Smart Card Types The chip – Memory card – Microprocessor multifunction card The connection – Contact card – Contactless card – Contact-Contactless card

Quick Start Training Smart Card Applications Identification card Credit and debit Digital cash/E-cash E-commerce E-register E-purse/E-wallet E-ticketing Information card Home banking Security access Library and resource access Toll payment Electronics benefits transfer

Quick Start Training Smart Card Standard Defined by the international standard ISO 7816 ISO 7816 –1 & -2 – Cover the physical dimensions and locations of the chip contacts ISO 7816 –3 & -4 – Govern the electronic signals, transmission protocols and inter- industry commands for interchange ISO 7816 –5 to –8 – Cover the number system, data elements, card SQL and security commands

Quick Start Training Smart Card Operation Connection and activation of the contacts – Contacts activation sequence are defined Electrical characteristics – Initial clock rate and I/O rate Answer to reset – At most 33 characters, defines protocol and format Transmission protocol – T=0, half duplex character transmission – T=1, half duplex block transmission
