As clarification, the Tokenization Sub-Group was created by the Mobile Payments Industry Workgroup whose work is facilitated by the Federal Reserve Banks of Boston and Atlanta. The work group was created earlier this year before the Apple Pay announcement as a number of mobile wallet schemes, EMVCo and The Clearinghouse had undertaken various forms of tokenizaton efforts. The work of the MPIW including a report from a June meeting in Austin TX on tokenization can be found at http://www.bostonfed.org/bankinfo/payment-strategies/mpiw/
