We pride ourselves on the extensive "research" we always do before purchasing a product on Amazon even if it is just a toothbrush or a dog toy, we still want to know what people are saying about the product before we spend our hard-earned cash on it. Personally, we can't even imagine purchasing a product without understanding how other people who have spent their own money on the product themselves feel about it.
The Amazon One device is designed to read the palm of your hand's distinct features that are completely unique to you in seconds. You are probably familiar with facial recognition technology if you are an iPhone user and this device reads your palm just as quickly but uses a more advanced technology that actually encrypts your palm image to protect it from theft.
