1 Alternating PICC and PCD support Songdo, September 2011 Prepared by: ACS, Bundesdruckerei, Infineon WG8 N 1836 TF2 N 705

2 Rationale  WG8 decided in April 2010 to let investigate the needs of mobile devices using the interface.  WG8 Convener reported accordingly to the SC17 Plenary in October 2010 and SC17 approved Resolution 639/10: New WG8 PWI into ‘Specifying the specific needs of mobile devices using the ISO/IEC methods‘ JTC1/SC17 approves the launch of a PWI assigned to WG8, into ‘Specifying the specific needs of mobile devices using the ISO/IEC methods’, with a view to developing an NP and accompanying working draft. If WG8 do not complete this within a year, they are to report back on progress to the next SC17 plenary.  Due to that Resolution 639/10 WG8 Members have been encouraged to work on the PWI and possibly to submit a Working Draft.  DIN has followed SC17’s offer and presents such a Working Draft, proposed in TF2 N 704 = WG8 N Page 2

3  Defines two devices  PCDProximity Coupling Device  PICCProximity Card or Object Page 3 ISO/IEC  PCD shall poll for Type A and Type B PICCs  PICC shall respond to Type A or Type B commands PCDPICC

4 Market needs  Upcoming devices should support both, PCD and PICC roles of ISO/IEC  Market increasingly brings up eID applications, which run purely according ISO/IEC Specifically mobile devices should be able to communicate with eID related contactless objects.  Also finance and transport sectors are interested in letting customers use contactless bank cards, resp. tickets, via mobile devices like mobile phones.  Such devices should be able to communicate with:  PICCs (in PCD role)  PCDs (in PICC role)  another equivalent device (which one is in PICC or PCD role is to be initially negotiated)  => creation of a new device fulfilling above needs Page 4

5 Page 5 ISO/IEC – Extended Proximity Device (EPD)  Extended Proximity Device supports PCD AND PICC Mode  Initial Mode is PICC Mode (either Type A or Type B)  Entering PCD Mode only if no external RF field is detected  In PCD Mode poll for Type A and Type B PICCs  Manual or automatic Mode selection EPD PCD ModePICC Mode

10 Conclusion  Market needs increasingly require that both PCD and PICC Modes should be supported in one device.  in particular in the eID, financial and transport sectors  Actual status of ISO/IEC & Amendments reflect a maximum of quality, functionality and applicability:  All parts of ISO/IEC & have been revised.  Amendments (soon published) for: Antenna Classes, EMD, Parameter Exchange, Very High Bit Rates.  Time has come to make available the much attractive interface to those devices which determine our daily life at a high degree, i.e. mobile phones.  Only minor adoptions in ISO/IEC are required to achieve that aim by the presented few further definitions proposed in the Working Draft (TF2 N 704 = WG8 N 1835), which lead to a new device category: the Extended Proximity Device (EPD) Page 10
