Change method, change request device and change system of values of stored data

Abstract

The invention provides a change method, a change request device and a change system of values of a plurality of stored data. The method comprises the following steps of: selecting the stored data of first priority, and sending a query request which comprises a target value to a storage terminal; after a response message which represents that the values of the stored data are smaller than the target value is received, acquiring the values of the stored data; according to a priority sequence of all stored data from high to low, continuously selecting other stored data until the sum of the values of all selected stored data is greater than or equal to the target value; after each stored datum is continuously selected, sending the query request which comprises current remaining amount to the storage terminal; and sending a change request to the storage terminal, and updating the values of all selected stored data. By the invention, the values of the plurality of stored data can be updated at one time, and the efficiency of updating operation is improved.

Description

technical field [0001] The invention relates to the field of electronic payment, in particular to a method for changing multi-stored data values, a request terminal and a system. Background technique [0002] At present, there are many kinds of e-wallet consumption cards in the group customer groups such as enterprises and campuses, such as special consumption cards such as meal cards, beauty cards, subsidy cards, etc., and general consumption cards such as general shopping cards and recharge cards in the park. In many consumption scenarios, multiple electronic wallets can be used for combined consumption. For example, when getting a haircut, if the balance of the beauty card is not enough to pay for this consumption, the balance in the beauty card is usually consumed first, and the insufficient part is consumed with a general recharge card. In the scenario of combined consumption of multiple electronic wallets, the existing solutions include two types: one is the scheme of...

Problems solved by technology

As a result, the balance of multiple electronic wallets, that is, the update operation of multiple stored data values ​​requires multiple interactive processes to complete, which takes a long time and is inefficient, reducing the number of terminals used to store stored data values ​​and requests to change stored data values The terminal (such as card) service life increases the cost
