Further, a system and method in accordance with exemplary embodiments may include receiving a payment initiation instruction from a customer, using a near field communication antenna, sending payment information to a point of sale device, using one or more computer processors, encoding data related to the payment as audio data, and transmitting the data related to the payment through an audio jack.
1. A contactless attachment, comprising:
a flexible ribbon that includes:
a secure element that securely stores a payment token, wherein the payment token is a surrogate value for a primary account number used to identify an account and is used to generate a cryptogram that is unique to a mobile transaction and is transmitted from the contactless attachment when the contactless attachment is used during the mobile transaction involving the account;
a radio frequency interface connected to the secure element, wherein the radio frequency interface includes a near field communication antenna that establishes a communication link between the contactless attachment and a proximity coupling device and transmits the payment token and cryptogram to the proximity coupling device via a radio frequency carrier frequency when conducting the mobile transaction involving the account;
an input/output interface that enables a communication link between the contactless attachment and a mobile device, wherein the input/output interface includes an audio encoder/decoder that encodes data to be transmitted to the mobile device via the communication link as attachment audio data and decodes audio data transmitted from the mobile device via the communication link, and wherein the input/output interface receives an account provisioning signal that includes the payment token;
an audio channel communication mechanism that is operably connected to the input/output interface and enables the contactless attachment to be connected to an audio jack of the mobile device to enable establishment of the communication link; and
a host controller interface that controls certain operations of the contactless attachment, including transmission of encoded data to the mobile device via the communication link and transmission of the payment token to the proximity coupling device via the radio frequency carrier frequency.
