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

  2. Rationale WG8 decided in April 2010 to let investigate the needs of mobile devices using the 14443 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 14443 methods‘ JTC1/SC17 approves the launch of a PWI assigned to WG8, into ‘Specifying the specific needs of mobile devices using the ISO/IEC 14443 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 1835. 19.09.2011 Page 2

  3. ISO/IEC 14443 Defines two devices • PCD Proximity Coupling Device • PICC Proximity Card or Object PCD shall poll for Type A and Type B PICCs PICC shall respond to Type A or Type B commands PCD PICC

  4. Market needs • Upcoming devices should support both, PCD and PICC roles of ISO/IEC 14443. • Market increasingly brings up eID applications, which run purely according ISO/IEC 14443. 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 beable 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 19.09.2011 Page 4

  5. ISO/IEC 14443 – Extended Proximity Device (EPD) 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 PCD Mode PICC Mode

  6. Scenarios EPD • Scenario 1: EPD in automatic mode alternation PCD Mode B A B A PICC Mode tPICC1 tPCD tPICC2 tPCD RF On RF Off t Start Check forexternal RF field tPICCi > tPCD tPICCi ≠ tPICCj

  7. Scenarios EPD • Scenario 2: EPD and PICC PCD Mode A B Cmd PICC Mode PICC tPICC1 tPCD tPICC2 RF On RF Off t PICC present Resp t

  8. Scenarios EPD • Scenario 3: EPD and PCD PCD Mode Cmd A PICC Mode PCD tPICC1 tPICC2 RF On RF Off Resp t RF On RF Off t

  9. Scenarios EPD 2 EPD 1 • Scenario 4: EPD and EPD PCD Mode PCD Mode Cmd A Cmd B A PICC Mode PICC Mode tPICC1 RF On RF Off Resp t tPICC1 tPICC2 RF On RF Off t

  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 14443 & Amendments reflect a maximum of quality, functionality and applicability: • All parts of ISO/IEC 14443 & 10373-6 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 14443 interface to those devices which determine our daily life at a high degree, i.e. mobile phones. • Only minor adoptions in ISO/IEC 14443 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). 19.09.2011 Page 10
