Abstract:
1. A method of wireless interfacing between elements within a terminal, the method comprising: detecting a request for processing a contactless transaction; establishing a link directly between a secure element and a contactless function (CLF) module on the terminal via a contactless interface within the terminal to allow the contactless transaction to start with an external terminal; and releasing the link after the contactless transaction is completed with the external terminal, wherein the link supports minimum requirements to allow data exchange using contactless protocols supported by the CLF module, wherein the detecting step includes detecting at least one of a power up procedure of the terminal, a wake up procedure of the terminal, a transaction from the secure element, and a transaction from the external terminal, wherein the wake-up procedure of the terminal is compatible with contactless application constraints, wherein the request is generated within the terminal or provided from the external terminal, wherein the secure element is at least one of a removable hardware element, a UICC, a smart card, a SIM card, a USIM card, and a storage medium, and the external terminal is an access gateway or a point-of-sale (PoS) terminal, and wherein after establishing the link with the secure element, one or more transaction requests and transaction responses are exchanged prior to releasing the link.
