A COMMUNICATIONS SERVER AND USER DEVICE FOR VALIDATING A TOKEN

Abstract:

A communications server for validating a token on a user device, the communications server comprising a memory storing: a list of locations; a first unique code associated with each location; a second unique code associated with each location; a user device product threshold; and a number of previously validated tokens for the user device, wherein the communications server is configured to: receive a first communication from the user device specifying the first unique code associated with a particular location; compare the number of previously validated tokens for the user device against the user device product threshold; when the number of previously validated tokens for the user device does not exceed the user device product threshold, send a reservation message to the user device, the reservation message causing the token on the user device to be reserved for use at the particular location; receive a second communication from the user device, the second communication specifying the second unique code associated with the particular location; and in response to receiving the second unique code associated with the particular location, send a validation message to the user device, the validation message causing the token on the user device to be validated.
