Near field communication payment method authenticated by both sides of deal

Abstract

The invention discloses a near field communication payment method authenticated by both sides of the deal. The method includes steps that 1, a binding relationship of one-to-one and one-to-many of a cell phone number and a bank account is established; 2, identity authentication on both sides of the deal through a cell phone is performed when a near field communication deal is needed; 3, after authenticating, the payee inputs amount collected to the cell phone, submits a collection request to a deal server, and the deal server generates a trade order and sends the order number to the payee; 4, the payee chooses a payer to trade, and sends the order number to the payer by means of near field communication; 5, the payer downloads the order information from the deal server, identifies the order information, inputs a payment code to the cell phone, and submitting a payment request; 6, information verification is performed, the trade is carried on when the verification is successful, otherwise, the trade is not carried on. The method of identity authentication is high in safety and reliability and easy to achieve based on the uniqueness of the cell phone number and background server.

Description

technical field [0001] The invention relates to a transaction method for realizing near-field payment by using mobile phone communication, in particular to a near-field payment method for mutual authentication of transaction parties. Background technique [0002] The existing near-field payment (face-to-face transaction) generally realizes the near-field payment by swiping magnetic stripe cards, smart cards, NFC tags, RFID cards and other identification cards at the POS machine, and the payment is made by the payee to the payer. After identity verification, send a transaction request to UnionPay or the bank to realize the transaction. In this way, there are many loopholes in the existing near-field payment authentication method, which may allow criminals to take advantage of it, such as: the payer cannot verify the legitimacy of the payee. As POS machines become more and more common, there is a risk of being forged by criminals; when customers provide bank cards to swipe th...

In this way, there are many loopholes in the existing near-field payment authentication method, which may allow criminals to take advantage of it, such as: the payer cannot verify the legitimacy of the payee

As POS machines become more and more common, there is a risk of being forged by criminals; when customers provide bank cards to swipe their cards, there is a risk that the customer's card will be copied, and the password entered may also be recorded, so that criminals can easily pretend to be Legitimate merchants take customers' bank card information and passwords; because customers do not have the ability to identify the legitimacy of POS machines, as the technical threshold for POS counterfeiting is getting lower and lower, the risk of this transaction mode is increasing at present

Therefore, people began to study and use more reliable payment methods, and now the use of mobile phones has become popular, and mobile phone numbers are unique, and mobile payment methods have also become a hot topic for people to study. For example, Chinese patent application No. 201110190955.4 discloses a The new mobile payment method realizes real-time mobile payment and does not require a dedicated POS machine, and solves the problems of limitations and high costs of traditional mobile payment methods. The main points of the technical solution are: a. Install barcode scanning software and mobile payment software in the mobile phone; b. When the user needs to make mobile payment, use the mobile phone scanning window to scan the barcode of the payee; c. The main chip of the mobile phone recognizes the barcode of the payee and parses out the relevant information of the payee; d. The user selects the payment account input Transaction amount and payment password; e. The main chip of the mobile phone sends the payment request information including the relevant information of the payee to the corresponding bank platform; f. The bank platform processes the payment request information and returns the processing result

The technical solution of this patent provides a mobile phone payment method that can authenticate the identity, but this authentication is based on the barcode provided by the payee, which still has risks, and it is difficult to ensure that all the information in the barcode is consistent. For authenticity, the account digital card number and account name in it may not be associated; therefore, we still need to improve it to ensure the authenticity of account information to the greatest extent and reduce transaction risks
