Amazon unveiled plans for the new "Amazon One" machine yesterday, a contactless card reader that accesses your payment information through just a wave of your hand. Users will insert their credit card and then hover their palms over the device in order to link the payment mechanism with their palm signatures. Once the card is on file, you'll be able to enter the store in the future just by holding your palm over the device for 1-2 seconds.

Amazon stresses that the device is contactless, which might prove to be greatly beneficial during a pandemic. The new device uses computer vision technology in real time to create the unique palm signature, a choice made by the company because they believe it to be more private than some other means of biometric authentication. 

According to Amazon, the data is secure - images are encrypted and sent to a secure area in the cloud where the palm signatures are created. The Amazon One device also does not require a customer to have an Amazon.com account in order to enter the store: just a palm and a phone number. 

Currently, the device is being trialed at two Seattle-area Amazon stores. Amazon also said that the device isn't just for stores: they envision it being used by third-parties, including non-Amazon retailers, office buildings, stadiums, and more.

What do you think about this? Too futuristic and too invasive? Let us know your thoughts!
