         31 . The contactless attachment of  claim 26 , wherein the financial account is a credit card account. 
     
     
         32 . The contactless attachment of  claim 31 , wherein the financial transaction is a credit card transaction. 
     
     
         33 . The contactless payment attachment of  claim 26 , wherein the secure element securely stores the account number upon account provisioning, and wherein the input/output module receives an account provisioning signal that includes the account number. 
     
     
         34 . The contactless payment attachment of  claim 26 , wherein the audio jack is coupled to the plug and wherein the host controller interface suspends transmission of an audio signal during use of the near field communication antenna. 
     
     
         35 . A method for initializing an attachment, comprising the steps of:
 receiving, via a network and within a mobile application associated with a financial institution executing on a mobile device, an encrypted secure element provisioning signal from a trusted service manager of the financial institution, the encrypted secure element provisioning signal including an account number that is used to identify an account at the financial institution and is transmitted from the attachment when processing a payment transaction relating to the account, wherein the attachment includes:   a tamperproof housing that protects the components of the contactless payment attachment;   a secure element within the tamperproof housing, the secure element having memory 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 secure element within the tamperproof housing 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 within the tamperproof housing, the 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;   a plug that is operably connected to the input/output module, protrudes from the tamperproof housing, connects the contactless payment attachment to an audio jack on a 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 extends into the tamperproof housing to receive a standard audio plug, the audio jack being operatively connected to the input/output module within the tamperproof housing to create an audio transmission channel between the plug and the audio jack; and   a host controller interface within the tamperproof housing and operatively connected to the secure element, near field communication antenna, and input/output 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;   using one or more computer processors within the mobile device and the mobile application associated with the financial institution executing on the mobile device, sending at least one secure element provisioning instruction, formed as encoded audio data, through the audio jack on the mobile device to the attachment;   decoding, using the audio encoder/decoder, the secure element provisioning instruction;   provisioning the attachment for use with the account by storing the received account number in the secure element;   binding the attachment to the mobile device; and   enabling, using the host controller interface, audio data other than the payment audio data to pass through the attachment via the audio transmission channel.
