         9 . The method as defined in  claim 1  wherein:
 the second device determines an application data format for the application data by parsing the application data to identify the presence of an indicator; and 
 the presence of the indicator informs the second device whether or not that the application data is formatted for a magnetic stripe transaction. 
 
     
     
         10 . An non-transient computer readable medium comprising instructions for executing the steps of  claim 1 . 
     
     
         11 . A method comprising a plurality of steps each being performed by hardware executing software, wherein the steps include:
 receiving, at a second device, a wireless communication containing a selection of an application deployed on a first device that is in wireless communication with the second device, wherein the selected application is for a payment service to be utilized in a transaction conducted on an account issued by an issuer;   sending, in a wireless communication from the second device to the first device, an identification of the selected application;   receiving, at the second device, a wireless communication containing a request from the first device for the capabilities of the second device for processing of the transaction; and   sending, in a wireless communication from the second device to the first device, an identification of the transaction processing capabilities from the second device;   receiving, at the second device, a wireless communication containing a selection of application data in response to the determination of the capabilities supported by the second device for the processing of the transaction; and   processing, at the second device, the application data as required by the selected application to approve or disapprove the transaction.   
     
     
         12 . The method as defined in  claim 11 , wherein the step of receiving, at the second device, the wireless communication containing the selection of the application deployed on the first device that is in wireless communication with the second device further comprises:
 receiving, at a second device, a wireless communication from a first device containing a list comprising:
 applications supported by the first device; and
