Systems and related methods facilitating payments with a mobile device are discussed herein. Circuitry in a networked-based central system, which may be a promotional system or payment system, may be configured to receive payment information from a consumer device. The consumer device may include circuitry configured to receive wallet identifying data from the central system. The wallet identification data may be used to secure messages between the consumer device and another device, such as a merchant device, over a wireless link. In some embodiments, the consumer device may receive promotional offers, such as deal vouchers or rewards, and make payments to the other device via the wireless link.
