Patent ID: 8108318

Claim:
A method of making a contactless payment at a point of sale (POS), comprising: securely downloading a payment application to a first secure element of a client device from a trusted service manager (TSM), wherein the first secure element is programmed to download the payment application in response to determining that the payment application is signed by the TSM; registering the client device with the TSM only through a second secure element of the client device, exclusive of the first secure element, wherein: the second secure element is physically separate from the first secure element, the client device is registered with the TSM for authentication by registering a biometric signature using a biometric sensor of the client device; storing the biometric signature in the second secure element of the registered client device for authentication, wherein: the biometric signature is excluded from the first secure element; storing a security key in the second secure element of the registered client device, wherein: the security key is excluded from the first secure element; storing a payment instrument in the second secure element of the registered client device, wherein: the payment instrument is excluded from the first secure element; executing the payment application resident on the first secure element; signaling, by the payment application, a biometric sensor of the client device to sense a biometric feature; sensing, by the biometric sensor in response to the signaling from the payment application, the biometric feature; generating, in response to the sensing, biometric data representative of the biometric feature and sending the biometric data to the second secure element via a secure tunneling circuit, comparing the biometric data to the biometric signature stored in the second secure element, generating a secure payment information message in response to an authentication including a match of the biometric data with the stored biometric signature, wherein the secure payment information message is encrypted in accordance with the security key, and the secure payment information message includes the payment instrument; and transmitting the secure payment information message to a POS reader by one of near field communication (NFC), infrared, short range wireless connectivity, secure short message service (SMS), or direct secure communication from the second secure element to the POS.
