The portable communication device then provides a universally unique identifier (UUID) of a base station of the resource provider to the N transaction processing system, which generates a hash using the UUID and a primary account number (PAN) of a portable transaction N device that is associated with the portable communication device. When the user conducts a transaction with the portable transaction 0 ---- device at the provider, the provider generates a separate hash from the UUID and the PAN and sends the hash to the transaction c)1: 1-1 processing system, A match between the hashes is taken into account as a positive indicator that the transaction is not fraudulent and c;;;;) the resource provider is complying with the system. ei C [Continued on next page] WO 2018/022104 Al IMEDIMOMMIDIRE10101011010H1010IIMMEMOIMIE SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
