ECMA-340@ ISO/IEC 14443 and ISO/IEC 15693 specify the radio frequency signal interface@ initialization@ anticollision and protocols for wireless interconnection of closely coupled devices and access to contactless integrated circuit cards operating at 13@56 MHz. This Standard specifies the communication mode selection mechanism@ designed not to disturb any ongoing communication at 13@56 MHz@ for devices implementing ECMA-340@ ISO/IEC 14443 or ISO/IEC 15693. This Standard requires implementations to enter the selected communication mode as specified in the respective Standard. The communication mode specifications@ however@ are outside the scope of this Standard.
