FIELD: physics.
SUBSTANCE: invention relates to servers and methods of processing transaction data. Method comprises receiving, by a server computer, device information and a resource provider identifier from a portable user communication device, wherein the resource provider identifier has been received by the portable communication device with the base station of the resource provider identified by the resource provider identifier; identifying identification data or a marker associated with the user's portable communication device, and transmitting the authentication data or the marker and the first biometric template to the portable communication device, wherein portable communication device transmits first biometric template to base station, wherein the base station receives a second biometric template from the biometric data collection device, which generates a second biometric template after receiving biometric data from the user, and compares the first and second biometric templates to determine whether the user is authentic.
EFFECT: technical result consists in improvement of reliability of transactions.
