InterChip USB (IC-USB) is intended as a low power variant of the standard physical USB 2.0 interface. IC-USB is being used primarily in mobile phones. The technology is standardised by ETSI in specification TS 102 600 as the official high speed interface for connections between the handset's main chipset and the UICC.

IP Multimedia Subsystem (IMS) is used within the 3G mobile phone technologies and enables the convergence of voice, video, data and mobile network technology by an IP-based infrastructure, IMS is the way to offer internet services everywhere using cellular technology and fills the gap between cellular and internet technology.

An IP Multimedia Services Identity Module contains parameters for identifying and authenticating the user to the IMS

ISO/IEC 14443 is defining the proximity standard of contactless communication. For both types the underlying communication scheme is half duplex with a 106 kbit per second data rate in each direction. In both cases, data transmitted by the card is load modulated with a 847.5 kHz subcarrier. However, both differ in the physical layer and the initialisation procedure (anticollision and selection).

ISO/IEC 7816 is the national standard for the "classic" contact based inter circuit cards (ICC) and specifies all electronic and mechanical characteristics of an ICC as well as its size, the arrangement and function of its contacts and its eventually existing magnetic stripes as well as the transmission protocols of data transmission between the chip card and terminal, its security devices and much more. The standard was developed by the ISO (International Organisation for Standardisation) and the IEC (International Electrotechnical Commission).
