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.

         7 . A payment processing system comprising:
 a networked device comprising processing circuitry configured to:
 generate a plurality of wallet identifying tokens, each wallet identifying token associated with a private key and consumer identifying data; 
 send the plurality of wallet identifying tokens to a consumer device; 
 receive from the consumer device, via a merchant device, a first wallet identifying token; 
 validate the first wallet identifying token based at least in part on whether the first identifying token is one of the plurality of wallet identifying tokens; and 
 send the consumer identifying data associated with the first wallet identifying token to the merchant device if the first wallet identifying token was validated. 
   
     
     
         8 . The payment processing system of  claim 7 , wherein the processing circuitry is further configured to validate the first wallet identifying token based at least in part on whether the first wallet identifying token was received from the merchant device during a payment period for the first wallet identifying token. 
     
     
         9 . The payment processing system of  claim 8 , wherein the payment period is initiated by the consumer device. 
     
     
         10 . The payment processing system of  claim 8 , wherein the payment period is initiated by the networked device. 
     
     
         11 . The payment processing system of  claim 8 , wherein the payment period is 12 hours. 
     
     
         12 . The payment processing system of  claim 8 , wherein the processing circuitry is further configured to
 receive from the consumer device, via a second merchant device, the first wallet identifying token;   validate the first wallet identifying token based at least in part on whether the first identifying token was received from the second merchant device during the payment period; and   send the consumer identifying data associated with the first wallet identifying token to the second merchant device if the first wallet identifying token was validated.   
     
     
         13 . The payment processing system of  claim 7 , wherein the processing circuitry is further configured to:
 receive, from merchant device, secured payment approval data that comprises consumer approval data signed with a first private key associated with the first wallet identifying token;   determine the first private key associated with the first wallet identifying token;   validate the secured payment approval data with the first private key; and   facilitate a financial transaction based on the secured payment approval data.   
     
     
         14 . The payment processing system of  claim 13 , wherein the consumer approval data comprises a one-way hash of transaction data signed with the first private key. 
     
     
         15 . The payment processing system of  claim 13 , wherein the processing circuitry is further configured to validate the secured payment approval data based at least in part on whether the secured payment approval data was received from the merchant device during a redemption period for the first Wallet identifying token. 
     
     
         16 . The payment processing system of  claim 15 , wherein the redemption period is initiated by the consumer device. 
     
     
         17 . The payment processing system of  claim 16 , wherein the redemption period is 24 hours. 
     
     
         18 . The payment processing system of  claim 7 , wherein the processing circuitry is further configured to send one or more additional wallet identifying tokens to the consumer device sufficient to maintain a reserve of wallet identifying tokens at the consumer device. 
     
     
         19 . The payment processing system of  claim 18 , wherein the reserve of wallet identifying tokens is 20.
