  "text": "The format shall be ID-1 (normal size, see ISO/IEC 7810).\nThe card shall support transmission protocol T=1 in compliance with ISO/IEC 7816-3. Additionally other transmission protocols may be supported, e.g. T=0, USB or contactless protocols.\nFor bit transmission the ‘ direct convention ’ shall be applied (see ISO/IEC 7816-3).\n(A) Supply voltage, programming voltage\nThe card shall work with Vcc = 3V (+/0.3V) or with Vcc = 5V (+/0,5V). The card shall not require a programming voltage at pin C6.\n(B) Answer to reset\nThe Information Field Size Card byte shall be presented at the ATR in character TA3. This value shall be at least ‘ 80h ’ (=128 bytes).\n(C) Protocol parameter selection\nThe support of Protocol parameter selection (PPS) according to ISO/IEC 7816-3 is mandatory. It is used for selecting T=1, if T=0 is additionally present in the card, and to negotiate the Fi/Di parameters for achieving higher transmission rates.\n(D) Transmission protocol T = 1\nThe support of chaining is mandatory.\nThe following simplifications are allowed:\nNAD Byte: not used (NAD should be set to ‘ 00 ’ ),\nS-Block ABORT: not used,\nS-Block VPP state error: not used.\nThe information field size device (IFSD) shall be indicated from the IFD immediately after ATR, i.e. the IFD shall transmit the S-Block IFS Request after ATR and the card shall send back S-Block IFS. The recommended value for IFSD is 254 bytes.",
