The application, published Thursday by the US Patent and Trademark Office, and dubbed “Method to send payment data through various air interfaces without compromising user data,” described a system based on the use of two secure wireless connections.
Specifically, the patent details a transaction between an iPhone owner and a retailer.
The transaction from the retail outlet would be based on NFC technology in order to establish a secure connection to the device that performs the operation.
In turn, this device would use a different wireless interface to complete the transaction.
Although previous Apple patents mentioned NFC functionality, the technology is not yet available on the iPhone.
