The COVID-19 pandemic accelerated the advent of a new era of contactless payment. In 2022, welcome contactless cardless payment with the palm of your hand! Just provide your mobile phone number and Amazon Prime QR Code, when you first enroll with the Amazon One service to activate both palms on the sensor. A fast procedure, somewhat reminiscent of activating the biometrics of your face on a new Iphone. Thereafter, all you need to do to pay, is to hover and let the Amazon One sensor recognize and identify one of your palms, for example, at a cash register, equipped with the biometric device. No more credit cards. No more searching for your Prime QR code with your phone app, or via Amazon.com. Checking out is as easy as a hover, effortless, and incredibly streamlined, not to mention safe, and truly contactless. You can even check out and pay, if you forget your purse (or wallet) in the car.
Needless to say that this invention is patented. The Amazon One, palm-powered contactless payment service is recited in the US utility patent application US20200302147A1, titled Biometric input device. The patent discloses the means for acquiring images of the user’s palms, while determining surface and subcutaneous features relevant to contactless identification of the user. The patent also discloses the means of processing recognition of the user's palm, for each new use of the service, whether for payment, entry, or other biometric identification purposes.
The patent Figure 1 below, together with an image of the Amazon One biometric device, both show a user hovering within the device's Field Of View (FOV) for identification of their palm. Hovering for Identification at the cash registers of Amazon-owned Whole Foods supermarkets, for example, or at other points of sale, or entry portals, such as libraries, hospitals, apartments, and offices, according to the extended scope of the invention.

The patent Figure 1 specifically depicts the biometric input device 102, according to the invention. A user’s hand 104 is hovering over the device 102 sensor window 106. A sensor assembly beneath the sensor window 106, comprises a camera with a field of view (FOV) 108. The sensor assembly (not depicted in Figure 1) might further comprise illuminators and polarizers used to obtain biometric data, in cooperation with the camera. Likewise, a mainboard assembly (not depicted in Figure 1) might additionally comprise a card reader, one or more processors, memory, output devices, controllers, and additional input devices. The patent Figure 1 additionally depicts an optional liquid crystal display device 110, able to display text, images and other information. The display device 110 might further comprise a touchscreen together with a haptics sensor. The device 102 also depicts a card reader 112, able to cooperate with a magnetic card 114. Finally, the device 102 also includes a stand 116, supporting the device, and possibly attached to a countertop.
Below, the abstract of the Amazon One biometric input device invention.
A biometric input device includes a sensor assembly that generates images of a user's palm that is within a field of view (FOV) using an image sensor behind a polarizer with a first polarization. The palm within the FOV is illuminated at different times with light having the first polarization and the second polarization. The images are acquired using polarized light and provide images of surface and subcutaneous features. The images may then be processed to identify the user. The device may include a touchscreen to provide information to the user or receive input from the user. The device may include a stand to mount the device at a convenient location, such as at an entry portal, point of sale, and so forth. [US20200302147A1]
