Ripple Smart Card

 

A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card that has embedded integrated circuits.   Smart cards are made of plastic, generally polyvinyl chloride, but sometimes polyethylene-terephthalate-based polyesters, acrylonitrile butadiene styrene or polycarbonate. Since April 2009, a Japanese company has manufactured reusable financial smart cards made from paper.

Smart cards can be contact, contactless, or both. They can provide personal identification, authentication, data storage, and application processing.

Smart cards serve as credit or ATM cards, fuel cards, mobile phone SIMs, authorization cards for pay television, household utility pre-payment cards, high-security identification and access badges, and public transport and public phone payment cards.. Smart cards may also be used as electronic wallets. The smart card chip can be "loaded" with funds to pay parking meters, vending machines or merchants. Cryptographic protocols protect the exchange of money between the smart card and the machine.  No connection to a bank is needed. The holder of the card may use it even if not the owner.

The subscriber identity modules (SIM) used in mobile-phone systems are reduced-size smart cards, using otherwise identical technologies.

Cryptographic smart cards are often used for single sign-on. Most advanced smart cards include specialized cryptographic hardware that uses algorithms such as RSA and Digital Signature Algorithm (DSA). Today's cryptographic smart cards generate key pairs on board, to avoid the risk from having more than one copy of the key (since by design there usually isn't a way to extract private keys from a smart card). Such smart cards are mainly used for digital signatures and secure identification.
