Card Acceptance Device is a smart card reader that allows to send command to a smart card.

The Card Emolution Mode is an NFC operating mode where the NFC device itself acts as an NFC tag, appearing to an external reader much the same as a traditional contactless Smart Card. This enables contactless payments and ticketing, where the UICC emulates a contactless card through the CLF.

CAT (Card Application Toolkit) consists of a set of commands defined for the communication between a card (R-UIM) and a handset with the goal to enable the card to initiate actions which can be used for various value-added services.

CCAT is the acronym for CDMA Card Application Toolkit and consists of a set of commands defined for the communication between a card (R-UIM) and a handset with the goal to enable the card to initiate actions which can be used for various value-added services.

CDMA is a form of multiplexing that allows several transmitters to send information simultaneously over one single communication channel (e.g.: wireless networks) instead of assigning a specific frequency to each user as it is usual for GSM systems. CDMA encodes individual conversations by random digital sequence. It offers a transmission speed of only up to 14.4 Kbps in its single channel form and up to 115 Kbps in an eight-channel form.

Code Division Multiple Access 2000 is - next to UMTS - one of the 3rd generation mobile phone technologies that allow a higher data rate than GSM (for 2G) does. CDMA2000 is an upgraded version of CDMA which can support mobile data communications at speeds ranging from 144 Kbps to 2 Mbps.

The Contactless Front-end (CLF) is the circuitry in the terminal which
- Handles the analogue part of the NFC communication
- Handles the communication protocol layers of the contactless transmission link
- Exchanges data with the UICC on the SWP interface

Contactless smart card is a smart card equipped with an antenna which reacts in presence of a electromagnetic field, in the radio-frequency spectrum, emitted by a special reading/writing device, allowing the microchip exchanging data with the outer world (whilst the antenna stays within a minimum distance from the reading/writing device.)

CSIM (CDMA subscriber identify module) is the name of the application on a removable security module (UICC) located in CDMA2000 mobile terminals. In its functionality the CSIM is comparable to the SIM in GSM. It is equipped with the crypto algorithm CAVE which is used for a multiplicity of cryptographic protected functions inside CDMA.
