A：昨天我经历了一件很有意思的事情。我在小区附近慢跑，然后想买瓶水，一家没有收银员也没有员工的便利店勾起了我的好奇心。便利店门上有一个二维码。扫描二维码后门自动打开，手机自动进入了一个网站。这个网站可以用于支付从店里拿走的所有商品。真的是非常神奇!你知道此

A: Yesterday I had a quite interesting experience. When I was jogging in my neighborhood, I wanted to buy a bottle of water, and I was intrigued by a convenience store with no cashier or staff. There was a QR code on the front door. Once I scanned the code with my phone, the door opened and my phone was hooked to a portal. This portal allowed me to pay just whatever goods I took off from the shelves. It was fantastic. Do you know that?
B：这几年大家都在讲线上线下一体化商超、无人零售商店这些概念化的零售产业也发展起来了。你说的这种便利店我听过，而且也去过。事实上，有家零售业巨头也推出了独具特色的无人零售商店品牌。它的门店入口看起来跟地铁站的闸机一样，只有在手机上下载了它的手机应用才能进。进去之后跟你在普通超市购物别无二致，而且还有现做现卖的熟食，没有结账柜台，需要什么直接拿走，手机应用自动结账。
A: This is amazing. But how does the app identify what products you’ve taken from the shelves? And if you decide to put something back, will it be removed from your cart?
B：这些问题问得很好，这当中肯定是用了高科技的。这家零售商店被问到类似问题的时候也说他们使用了最先进的计算机视觉系统和机器学习软件。简单来说，就是装在货架上的摄像头可以自动识别所有货架上的产品，“看”出来你到底买了什么东西，有没有把拿走的又放回去。
A: Awesome. I think I am never going back to the supermarket again. I hate being stuck in long lines, especially when people in front of me have loads of things to check out and I just have a few items. Therefore, I think those stores will definitely disrupt the current supermarket industry and hurt many cashiers’ jobs.
B：没错，无人商超的普及必然会或多或少地影响收银员的饭碗。但是，好在旧的岗位消失的同时，也有新的工作岗位会出现。这些店里仍然需要员工给顾客做技术指导，也需要做熟食的厨师。只要做好再就业培训，就是及时止损，毕竟这是自动化发展带来的必然结果。
