Tips to prevent duplicate payments and false payments in PHP mall development

With the popularity of online shopping and the rapid development of e-commerce transactions, more and more merchants are beginning to shift their business to the Internet. In response to this situation, major e-commerce platforms have slowly begun to grow and provide merchants with a variety of services. Among them, PHP mall development has become the first choice for many merchants. However, there are also some technical difficulties in developing a PHP mall, among which preventing duplicate payments and false payments are important and difficult to solve. This article will discuss the techniques for preventing duplicate payments and false payments in mall development.

1. Prevent duplicate payments

Preventing duplicate payments is a very important part of e-commerce platform development. If there are no effective measures, users may accidentally pay twice due to negligence or other reasons, wasting users' funds, and also affecting the reputation of the merchant.

1. Add a delay time

A simple method is to set a delay time for the payment order after the user completes the payment, such as 10 minutes. During this period, if the user enters the payment page again, they will find that the payment has been made. This method requires adding a certain duplication detection mechanism to the program design to ensure that there will be no misjudgments.

2. Add order status attribute

Merchant can add a status attribute to the order to record the processing status of the order, such as "unprocessed", "paid", etc. When the user pays successfully, the merchant needs to change the status of the order and set it to "paid". If the user pays repeatedly, the order has been modified to the "paid" status, and the user will be prompted "the order has been paid" during the operation to avoid repeated payments.

3. Add a verification mechanism on the front end

Adding a verification mechanism on the payment page is also a feasible solution. For example, set a verification code so that after the user successfully pays, the verification code will take effect. When entering the payment page again, the verification code needs to be entered to make payment, thereby avoiding repeated payments.

2. Preventing false payments

False payments are a common problem in e-commerce platform development, and it is also very serious. Fake payments are divided into two situations, one is operated by malicious users, and the other is when the payment channel is cracked. Here are a few tips to prevent fake payments.

1. Join basic verification

When users submit a payment request, basic verification is required. For example, verifying the authenticity of information submitted by users, such as phone number, ID number, bank card number, etc., all need to be verified. Only if the verification is passed can you proceed to the next step.

2. Combined use of multiple payment methods

Merchant can add multiple payment methods on the payment page, such as Alipay, WeChat, UnionPay, etc. By combining multiple payment methods, the difficulty of false payments can be increased.

3.Backend reconciliation

After the payment is successful, the merchant needs to reconcile. Prevent false payments by comparing payment orders with bank statements to ensure the amount corresponds to the order.

4. Add a risk control mechanism

Merchant can also add a risk control mechanism, such as setting a daily cumulative payment limit for each user, intelligently identifying abnormal operations, etc. When an abnormal operation occurs, it can be automatically intercepted and the user can be prompted to verify the information.

Conclusion:

Preventing duplicate payments and false payments are two issues that need to be paid attention to in the development of e-commerce platforms. The above tips are just one of the solutions that merchants need to consider. Merchants need to decide which techniques to adopt based on their own business conditions. No matter which method is used, merchants need to formulate detailed plans and complete technical architecture to support and guarantee it. To ensure that merchants can conduct business smoothly.
