System and method of processing payment transactions via mobile devices

A computer-implemented method for securing mobile transactions, the method comprising:

• receiving, by a mobile computing device, an input that corresponds to a transaction type selected from a plurality of transaction types presented on a displayed user interface via a touchscreen of the mobile computing device;
• based at least in part on the received input, receiving, by the mobile computing device, one or more pieces of identification information encrypted by a reader device coupled to the mobile computing device, wherein the one or more encrypted pieces of identification information corresponds to the selected transaction type;
• generating, by the mobile computing device, a request to process a transaction that corresponds to the selected transaction type based at least in part on the received one or more encrypted pieces of identification information;
• and
• transmitting, by the mobile computing device, the generated request to a remote server configured to process requests generated based on the one or more encrypted pieces of identification information corresponding to any one of the plurality of transaction types presented on the displayed user interface of the mobile computing device.

A secure mobile transaction device, comprising:

• one or more processors;
• and
• one or more computer storage media storing computer-usable instructions that, when used by the one or more processors, cause the one or more processors to:
• receive an input that corresponds to a transaction type selected from a plurality of transaction types presented on a touchscreen of the mobile computing device via a user interface;
• based at least in part on the received input, receive a piece of identification information encrypted by a coupled reader device, wherein the encrypted piece of identification information corresponds to the selected transaction type;
• generate a request to process a transaction that corresponds to the selected transaction type based at least in part on the received encrypted piece of identification information;
• and
• transmit the generated request to a remote server configured to process transaction requests generated based on encrypted pieces of identification information that each corresponds to one of the presented plurality of transaction types.
