The intertwining of telecom, banking, and M2M/IoT produce a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.
Specification for a single-wire connection between the SIM card and an NFC chip in a cell phone. SWP is an interface between CLF and UICC. It is a contact-based protocol that is used for contactless communication. C6 pin of UICC is connected to CLF for SWP support. It is a bit-oriented full-duplex protocol which means that simultaneous transmission and reception are possible. CLF acts as a master and UICC as a slave. CLF provides the UICC with energy, a transmission clock, data, and signal for bus management. The data to be transmitted is represented by the binary states of voltage and current on the single wire.
