Abstract:
1. A contactless payment attachment, comprising: a universal integrated circuit card having a secure element that securely stores an account number upon account provisioning and which is used to identify a financial account and is transmitted from the contactless payment attachment when processing a payment transaction relating to the financial account; a near field communication antenna connected to the universal integrated circuit card that receives the account number from the secure element and transmits the account number to a point of sale device when processing the payment transaction relating to the financial account; an input/output module having an audio encoder/decoder that encodes information related to the payment transaction as payment audio data and decodes payment audio data, the input/output module receives an account provisioning signal that includes the account number; an encryption/decryption module that encrypts information being transmitted to a mobile device and decrypts encrypted information received from the mobile device; a plug that is operably connected to the input/output module, connects the contactless payment attachment to an audio jack on the mobile device, and provides power to the contactless payment attachment from the mobile device when the plug is connected to the audio jack on the mobile device; an audio jack that receives a standard audio plug, the audio jack being operatively connected to the input/output module to create an audio transmission channel between the plug and the audio jack; and a host controller interface operatively connected to the universal integrated circuit card, near field communication antenna, input/output module, and encryption/decryption module, wherein the host controller interface controls certain operations of the contactless payment attachment, including enabling audio data other than the payment audio data to pass through the contactless payment attachment via the audio transmission channel.
