CCID (chip card interface device) protocol is a USB protocol that allows a smartcard to be connected to a computer via a card reader using a standard USB interface, without the need for each manufacturer of smartcards to provide its own reader or protocol. [1]
A card reader is a data input device that reads data from a card-shaped storage medium and provides the data to a computer. Card readers can acquire data from a card via a number of methods, including: optical scanning of printed text or barcodes or holes on punched cards, electrical signals from connections made or interrupted by a card's punched holes or embedded circuitry, or electronic ...
The CCID (Chip Card Interface Device) is a USB protocol that allows a smart card to be interfaced to a computer using a card reader which has a standard USB interface. This allows the smart card to be used as a security token for authentication and data encryption such as Bitlocker .
Access to smart cards is provided through an enhanced version of the OpenCard Framework. Drivers are included for most ISO/IEC 7816-4 compliant smart cards, PC/SC and CT-API card readers. The platform also provides cryptographic support through the Java Cryptography Extension (JCE) with the Bouncy Castle Crypto API.
Contactless smart card readers use radio waves to communicate with, and both read and write data on a smart card. When used for electronic payment, they are commonly located near PIN pads, cash registers and other places of payment. When the readers are used for public transit they are commonly located on fare boxes, ticket machines, turnstiles ...
OpenSC is a set of software tools and libraries to work with smart cards, with the focus on smart cards with cryptographic capabilities. [2] [3] OpenSC facilitate the use of smart cards in security applications such as authentication, encryption and digital signatures. OpenSC implements the PKCS #15 standard and the PKCS #11 API.

In the context of smart cards, an application protocol data unit (APDU) is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange. [1]
