Second, strengthen the risk prevention and control of bank card magnetic strip trading

(1) Fully close the magnetic stripe transaction of the chip magnetic strip composite card. All commercial banks shall strictly implement the Notice of the People's Bank of China on Further Strengthening the Risk Management of Bank Cards (Yinfa [2016] No. 170), and completely close the magnetic stripe transaction of the chip magnetic strip composite card from the card issuing end.

(2) Using transaction security locks to enhance the fineness of risk prevention and control. Since October 15, 2017, commercial banks should provide bank card transaction security lock services through outlet counters, online banking, mobile banking, telephone banking, etc., and guide cardholders to independently set transaction types, channels, regions, time slots, and quotas. Such parameters, limit the magnetic strip trading scenario as needed, and improve the degree of risk prevention and control.

(3) Establish a risk prevention and control mechanism based on big data technology. Before the end of August 2017, other commercial banks will complete the construction of bank card risk prevention and control system based on big data technology before the end of December 2017 to improve the risk management level of magnetic stripe transactions. First, based on the characteristics of high-risk transactions and the characteristics of cardholders' behavior, a risk assessment model was established. The second is to implement differentiated risk prevention and control based on the risk level. For magnetic stripe transactions with high risk and high degree of suspiciousness, measures such as accurate identification and real-time interception are adopted. The third is to continuously optimize the risk assessment model through transaction behavior analysis and machine learning to improve the success rate of fraudulent transaction interception and effectively improve the security protection of bank card transactions.

(4) Establish and improve the classification and classification management mechanism for bank card magnetic stripe transactions. From August 1, 2017, each commercial bank shall implement transaction classification and classification management according to the transaction amount and transaction frequency. For a single transaction with a value of more than 10,000 yuan, the cardholder should be guided to use the transaction security lock. For a single transaction with a value of more than 20,000 yuan, the magnetic stripe transaction risk reminder and transaction reminder should be carried out through voice, SMS, data (such as mobile banking, instant messaging). For high-risk transactions identified by big data analysis, additional transaction verification should be performed to further verify the true identity of the transaction initiator. For abnormal transactions with too high a single day frequency, measures such as refusal of transaction authorization should be taken.

Third, the job requirements

(1) The branches of the People's Bank of China shall, under the leadership of the Bank's Bank Risk Management Leading Group, take measures such as statement statistics, on-site inspections, and briefings, and supervise the commercial banks and payment institutions within their jurisdiction to effectively implement the requirements of this Notice.

(2) Commercial banks and payment institutions shall establish an organization and coordination mechanism for implementing the requirements of this Notice, formulate detailed work plans, implement the responsibility of the lead department, grasp the key time nodes, and accelerate the construction and transformation of systems such as card issuance, receipt, and big data. Effectively improve the risk prevention and control level of bank cards.

(3) The bank card clearing institution shall fully support the relevant units to do the work of marking, upgrading, and systematically transforming the non-standard bank card acceptance terminals, and ensuring the effective implementation of various measures. In conjunction with member institutions, we will further improve the relevant rules for the transfer of false card fraud risk liability and error handling, and clarify the risk liability and error handling procedures for fraudulent card fraud, such as card issuance and receipt.
