考了一下古，Pay by touch 2006年开始试点，但是那个科技公司2008年就破产了。不是技术问题，而是没有市场。当年看到这项技术的时候，真是对美国的技术进步佩服得不得了。这才十几年的功夫，美国就变得不忍直视。唉，真是三十年河东，三十年河西啊。 https://www.chicagobusiness.com/node/471936/printable/print Pay By Touch ends at JewelMoneé Fields-white (Crain's) -- Pay by Touch, a technology system that allowed shoppers to pay through fingerprint verification, has been shut down at retailers -- including Jewel-Osco. California-based Solidus Networks Inc. says on its Web site in an announcement dated Wednesday that it was ceasing processing biometric transactions as of 1159 p.m. Wednesday. The move comes three months after Solidus filed for Chapter 11 bankruptcy protection. "As part of the company's restructuring, it was determined that the enterprise could no longer support the biometric authentication and payment system as it currently exists, based on lack of funding and current market conditions," Solidus says on its site. "Other non-biometric Solidus Networks business units will continue on their current business paths," the announcement says. Jewel, a division of Supervalu Inc. that has about 184 stores, has disabled all Pay by Touch machines at its stores and is working on removing them, a spokesman said. Signs have been posted through the Jewel chain apologizing to customers for the inconvenience, he said. Jewel rolled out the program to its stores in January 2006 after piloting the program the year before. The Chicago Tribune reported the news earlier Thursday.

千万别引入美国，否则某族裔直接砍人手指。。。
+1 我第一反应也是这个。以后暴力犯罪真以剁手为主了
估计是怕楼上说的剁手指。
美国多数人已经接受了信用卡，debit card，觉得很安全。后来有一些接受了apple pay之类，据（苹果）说更安全，不过接受度依然不足10%，如果改用指纹或者其它生物识别技术，估计需要很长的时间才能普及。除非在一个完全新兴市场，或者有大力的行业支持。

那和支付宝刷脸支付是同类型的，都是需要采集个人Biometrics的。这类技术要在美国推广基本上都没戏，Privacy Law太严了。当年Jewel-Osco要员工刷指纹还惹了一个Class Lawsuit。
美国领先的技术多了去了。也不能什么都是美国来实现吧？其他国家有点事情干是对的。何况这种技术如果不能排除1,被切指头的风险，2,被采集生物指征的风险，那么连我都不屑一顾。当年终结者二里不就有剁指头去开门的情节吗？不稀罕。
很多所谓的刚出锅的技术其实美国早就有了，各种现实条件不太支持应用而已，所以就被强国拿去发展，比如那种基因改造技术。反正科学要是没有了道德基础，弄出怪物也不是个事。
刷脸好多了。至少还可以加一步眨眼睛来验证。
终结者二 有这情节？
你以前没听说过日立？
不一定是指纹，只要有生物纹理独特性（如肘关节皮肤纹），在技术上是一样的。
那个黑人博士的实验室需要指纹还是眼球认门通关的。
