Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for transmitting, as part of a polling loop, a value added services (VAS) command that includes capability data corresponding to a payment terminal. For example, the payment terminal can transmit a VAS command that advertises the payment terminal's capabilities as part of a polling loop. The payment terminal can listen for a response to the VAS command and, after receiving a response, the payment terminal may initiate a VAS protocol. The VAS command can also specify a mode in which the payment terminal is operating, such as a payment-only mode, a VAS mode, a payment-plus-VAS mode, etc.

Abstract: An adaptor in accordance with the present invention allows a conventional magnetic stripe card POS reader to receive information from contact-based or wireless sources while maintaining the concurrent ability of the reader to interact with a magnetic stripe card. In accordance with one embodiment of the present invention, the adaptor includes an inductor capable of generating a magnetic field of sufficient power to couple with a head of a magnetic stripe card reader through the housing of the reader device. In this manner, the adaptor can be positioned external to the reader device, leaving the slot of the reader accessible for conventional interactions with magnetic stripe cards. Selective inductive communication with individual heads of the reader device may exploit their differing sensitivity to external magnetic fields generated by the adaptor.
