Mastercard plans to cancel credit card numbers and switch to tokenization technology to reduce the risk of information leakage

According to Singapore's Lianhe Zaobao, Mastercard is planning to do away with traditional credit card numbers and adopt "tokenization technology" (tokenization) to combat online fraud. The technology replaces sensitive data such as credit card numbers with randomly generated sequences of numbers (tokens) to reduce the risk of data breaches. Mastercard CEO Mibach said the company will expand its use of the technology and replace traditional passwords with biometrics such as fingerprints or facial scans. The measure is in response to the growing problem of online payment fraud, which is expected to exceed $91 billion by 2028.
Miebach pointed out that the conventional thinking in the past was to protect data and transactions through passwords to ensure security, but this practice has gradually become a security bugs. But "authentication technology" replaces sensitive information with "tokens", which cannot be resolved even if the data is illegally accessed by hackers. In addition, "authentication technology" also helps companies comply with data protection regulations, such as the European Union General Data Protection Law (GDPR) and the Payment Card Industry Data Security Standard (PCI DSS). Mastercard said that by the end of the century, all e-commerce transactions in Europe are expected to be replaced by "tokens".
