如果我要在荧光灯灯和其中一个Supermegaultra Walmarts的哔哔声中购物，我感到压力很大，而且我不需要购物车告诉我。但是，当购物者特别紧张时，这家零售巨头可能有一天可以通过生物识别技术知道。
CB Insights报告沃尔玛提出了专利对于“生物识别反馈车手柄”，可以在触摸购物车手柄时测量购物者的脉搏，温度和力量水平。(It is worth clicking on the actual patent application to view Walmart’s “illustration” of the system, which appears to have been created by Microsoft Paint.) The application notes in its summary that the data could be collected and measured against a baseline to alert store employees when a customer “may need assistance.” According to CB Insights, the carts’ computer system could also potentially flag a situation as serious enough to warrant an automatic call for medical assistance.
沃尔玛有多少人紧急情况？您可能会问。截至七月，美国拥有3,565个沃尔玛超级中心；393沃尔玛折扣店；704沃尔玛邻里市场；还有597个山姆俱乐部（也由沃尔玛拥有）。在很多地方，客户可能会遇到紧急情况。我们只能希望这些购物车永远使用我们的生物识别数据，而不是向我们宣传血压药物。
