89. OVERVIEW OF SMART CARD

A "smart card" is also characterized as follows:Dimensions are normally credit card size. The ID-1 of ISO/IEC 7810 standard defines them as 85.60 × 53.98 mm. Another popular size is ID-000 which is 25 × 15 mm (commonly used in SIM cards). Both are 0.76 mm thick. Contains a security system with tamper-resistant properties (e.g. a secure cryptoprocessor, secure file system, human-readable features) and is capable of providing security services (e.g. confidentiality of information in the memory).


Asset managed by way of a central administration system which interchanges information and configuration settings with the card through the security system. The latter includes card hotlisting, updates for application data.
Card data is transferred to the central administration system through card reading devices, such as ticket readers, ATMs etc.


BenefitsSmart cards can be used for identification, authentication, and data storage.[1]Smart cards provide a means of effecting business transactions in a flexible, secure, standard way with minimal human intervention.Smart card can provide strong authentication[2] for single sign-on or enterprise single sign-on to computers, laptops, data with encryption, enterprise resource planning platforms such as SAP, etc.A smart card, chip card, or integrated circuit card (ICC), is in any pocket-sized card with embedded integrated circuits which can process data.


This implies that it can receive input which is processed — by way of the ICC applications — and delivered as an output. There are two broad categories of ICCs. Memory cards contain only non-volatile memory storage components, and perhaps some specific security logic. Microprocessor cards contain volatile memory and microprocessor components. However, concern is also expressed about the extensive cost and potential abuse of hi-tech smartcards.
