Claim Text:
1. A contactless attachment, comprising: a housing that protects components of the contactless attachment; an International Organization for Standardization/International Electrotechnical Commission 14443 (ISO/IEC 14443) compliant secure element within the housing that securely stores an account number upon account provisioning which is used to identify an account and is transmitted from the contactless attachment when the contactless attachment is used during a transaction involving the account; a radio frequency interface connected to the ISO/IEC 14443 compliant secure element within the housing, 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 account number to the proximity coupling device via a radio frequency carrier frequency when conducting the transaction involving the account; an encoder/decoder within the housing that enables an audio channel communication link between the contactless attachment and a mobile device and encodes data to be transmitted to the mobile device via the audio channel communication link as attachment audio data and decodes audio data transmitted from the mobile device via the audio channel communication link, wherein the encoder/decoder receives an account provisioning signal that includes the account number; an approximately 3.5 millimeter 4 pole standard audio plug that is operably connected to the encoder/decoder, protrudes from the housing, and connects the contactless attachment to an audio jack of the mobile device to enable establishment of the audio channel communication link, and is capable of providing power to the contactless payment attachment from the mobile device when the approximately 3.5 millimeter 4 pole standard audio plug is connected to the audio jack on the mobile device; a host controller interface within the housing that controls certain operations of the contactless attachment, including transmission of encoded data to the mobile device via the audio channel communication link and transmission of the account number to the proximity coupling device via the radio frequency carrier frequency; a power source that supplies power to the ISO/IEC 14443 compliant secure element, radio frequency interface, encoder/decoder, and host controller interface in a manner that enables the contactless attachment to be self-powered; and a keychain that includes an audio plug receptacle that is capable of receiving the approximately 3.5 millimeter 4 pole standard audio plug in a manner that couples the housing to the keychain and a keychain portion that enables attachment of the keychain to another object.
