Some of those standards and specs are industry-specific applications. International standards and specifications cover smart card technology. They can also be used as tokens for multifactor authentication ( MFA). Smart cards capable of short-range wireless connectivity can be used for contactless payment systems. The payment card industry's support of smart cards for the Europay, Mastercard and Visa ( EMV) card standard has driven the distribution of smart cards. Smart cards are used for a variety of applications but are most commonly used as credit cards and other payment cards. Cards with microcontroller chips can perform on-card processing functions and manipulate information in the chip's memory. Smart cards are designed to be tamper-resistant and use encryption to provide protection for in-memory information. The chip on a smart card can be either a microcontroller or an embedded memory chip. They connect to a reader either by direct physical contact - also known as chip and dip - or through a short-range wireless connectivity standard such as radio-frequency identification ( RFID) or near-field communication. Smart cards are typically the same size as a driver's license or credit card and can be made out of metal or plastic.
