Electronic payment device and electronic payment system

Abstract

The invention relates to the technical field of electronic payment, and particularly to an electronic payment device and an electronic payment system. The electronic payment device comprises an input end, a microprocessor and a display terminal. The microprocessor is used for monitoring a payment amount display instruction which is output from a cash register through the input end, acquiring data of a payment amount and displaying the payment amount on the display terminal. Simultaneously, a two-dimensional code which is used for cash collection is generated according to the data of the payment amount and a prestored cash receiving account number; and furthermore the two-dimensional code is displayed on the display terminal. According to the electronic payment device and the electronic payment system, software and hardware of the cash register are not changed; the electronic payment device can be mounted just through utilizing an original interface of the cash register, thereby preventing communication line increase and cost increase, and realizing no requirement for debugging. According to the electronic payment device and the electronic payment system, the payment amount is acquired through monitoring the payment amount display instruction which is output from the cash register; furthermore the two-dimensional code for cash collection is generated through the prestored cash receiving account number and is displayed on the display terminal; and payment can be realized through scanning the two-dimensional code by a customer, thereby realizing no requirement for change and obtaining high convenience and high speed.

Description

technical field [0001] The invention relates to the technical field of electronic payment, in particular to an electronic payment device and an electronic payment system. Background technique [0002] Existing electronic payment devices generally have two payment methods. First, it is necessary to transform the cash registers in shopping malls or supermarkets. That is, the card swiping POS machine needs to be connected to the serial port of the cash register, and the software of the cash register is modified to transmit the collected amount to the card swiping POS machine through the serial port. The cost is high and the workload is huge, and it is not easy to implement. Second, the card is swiped after manually inputting the amount for swiping the card at the POS machine, which is inefficient and error-prone. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electronic payment device and an electronic payment...

Problems solved by technology

First, it is necessary to modify the cash registers in shopping malls or supermarkets

That is, the card-swiping POS machine needs to be connected to the serial port of the cash register, and the software of the cash register is modified to transmit the collected amount to the card-swiping POS machine through the serial port. The cost is high and the workload is huge, and it is not easy to implement.

Second, the POS machine manually enters the amount of the card before swiping the card. This operation method is inefficient and error-prone
