SWP is an interface between contactless frontend (CLF) and [[universal integrated circuit card]] (UICC/SIM card chip). 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, i.e. at the same time transmission as well as reception is possible. CLF acts as a master and UICC as a slave. CLF provides the UICC with energy, a transmission clock, data, and a signal for bus management. The data to be transmitted are represented by the binary states of voltage and current on the single wire. |
