Consumer device payment token management

Abstract

Systems and related methods for facilitating payments via a consumer device carried by a consumer are discussed herein. Wallet identifying tokens may be used to secure messages between the consumer device and the merchant device over a wireless link. For example, the merchant device may include circuitry configured to wirelessly receive a wallet identifying token from a consumer device and to transmit the wallet identifying token to the central system. In response, consumer identifying data associated with the wallet identifying token may be received by the merchant device from the central system. In some embodiments, payments may be secured via limiting the lifetime of wallet identifying tokens after initial use.
