2. The cardholder's single consumption exceeds 5000 yuan or 10000 yuan.
Because the magnetic stripe card is easy to use, in order to ensure the safety of consumption, the single consumption exceeds 5000 yuan or 10000 yuan, and the bank needs to authenticate the magnetic stripe card. Generally, the authentication of magnetic stripe cards requires magnetic stripe cards and mobile phone numbers reserved by banks. After the verification is successful, you can continue to use it.
1. Why do pos machines need to be certified to brush magnetic stripe cards?
For the safety of personal funds, the magnetic stripe card is easy to be broken, which leads to the insecurity of the information in the card, while the chip card is not available at present, and the security is relatively high. The magnetic stripe card was stolen, and there were many incidents of bill adjustment. So generally speaking, when a magnetic stripe card has a large transaction, there will be a hint of transaction failure, such as the POS machine displaying code 94. This is a means for payment companies to protect the interests of merchants, but chip cards do not have this problem.
Second, how does the pos machine authenticate the magnetic stripe card?
The steps to authenticate the magnetic stripe card by pos machine are as follows (take the pos machine of the shopkeeper as an example):
1, log in to the shopkeeper APP, enter the home page and select "magnetic stripe card authentication";
2. Fill in personal name, ID number, reserved mobile phone number and credit, and finally submit the certification. After the certification is submitted, you can check the certification record in the upper right corner to see if the certification is successful;
3. If the authentication record shows that the authentication has been successful, but the transaction amount is more than 5,000 yuan, it still shows that the magnetic stripe card needs authentication, so you can call customer service directly.
