Netizens have mixed reactions to palm payment. Some netizens thought, "It's a very good function. The error rate of palmprint recognition is low, and it's really convenient."

Under the condition of ensuring safety, "palm swiping" can indeed become one of the auxiliary means for payment verification. While "swipe palm" technology improves the convenience of financial services, it also has some application risks, such as information leakage risk and algorithm vulnerability risk.

It is recommended that consumers enhance their awareness and ability to identify and prevent fraud, and properly protect their sensitive personal information to reduce the risk of information leakage.
