Abstract
The invention discloses a near field payment method for a smart phone. The scheme is that: the phone without a near field communication (NFC) chip and a smart memory card with an encryptionalgorithm are adopted, a digital certificate of a bank card is downloaded into the smart memory card matched with the digital certificate as a paymentvoucher, the smart memory card is inserted into the smart phone, and near field communication trading software is installed in a memory of a body of the smart phone or in the smart memory card. The smart phone is held close to a point of sale (POS) terminal,performs near field communication with the POS terminal by utilizing own wireless communication technology of the phone and obtains bank card operation authority by authenticating the digital certificate, and a trading amount is displayed on the POS terminal and the phone. The near field communication trading software in the smart phone realizes mobile payment. In the method, the use of the NFC chip is avoided and an NFC antenna is not required to be arranged or modified in the smart phone. When NFC mobile phones are not popularized in China, the method can be used as a transitional scheme for the near field payment of the phone.
Description
technical field [0001] The invention relates to a near-field payment method for a smart phone. Background technique [0002] Mobile payment is a service method in which users use mobile terminal devices to pay for the goods or services they consume. The mobile terminal device usually refers to a mobile phone. At present, the mobile phone near-field payment method is mainly based on the short-range wireless communication technology (ie, NFC, Near Field Communication) to complete the account payment. The method for realizing mobile phone payment based on short-distance wireless communication technology can support various functions such as electronic payment and data downloading. There are two technical solutions for mobile payment based on short-range wireless communication technology. The first is to directly use a mobile phone with an NFC chip; the second is to install an identification device on a smartphone without an NFC chip. Wherein, the identification device is an ...
