Infrared cameras analyze both a user's palm print and a unique pattern of veins under their skin.

红外热像仪既能分析用户的掌纹图案，也能分析其皮肤下独特的静脉纹路。

Guo Rizen oversees the lab that began developing this technology in 2019. He says the double verification of palm prints and veins helps prevent identity theft.

郭润增负责监督开发这项技术的实验室，该实验室于2019年起开发这项技术。他说，掌纹图案和静脉图像的双重验证有助于防止身份盗窃事件。

With face scanning technology, people can look a lot like each other like twins, but with palm payments, even brothers and sisters who look alike have unique palm prints and veins.

使用面部扫描技术的话，有时会出现两个人长相酷似双胞胎的情况，但即使是长得很像的兄弟姐妹之间使用掌纹支付时也不会出现这种情况，因为每个人都的掌纹和脉络都是独一无二的。
