Forget the titanium Apple Card &mdash Amazon's latest payment method uses flesh and blood.
The e-tailing giant's engineers are quietly testing scanners that can identify an individualhuman hand as a way to ring up a store purchase, with the goal of rolling them out at itsWhole Foods supermarket chain in the coming months, The Post has learned.
Employees at Amazon's New York offices are serving as guinea pigs for the biometrictechnology, using it at a handful of vending machines to buy such items as sodas, chips, granola bars and phone chargers, according to sources briefed on the plans.
The high-tech sensors are different from fingerprint scanners found on devices like the iPhoneand don't require users to physically touch their hands to the scanning surface.
Instead, they use computer vision and depth geometry to process and identify the shape andsize of each hand they scan before charging a credit card on file.
The system, code-named "Orville," will allow customers with Amazon Prime accounts to scantheir hands at the store and link them to their credit or debit card.
It's accurate to within one ten-thousandth of 1%, but Amazon engineers are scrambling toimprove it to a millionth of 1% ahead of its launch, the source said.
Amazon hopes to introduce the tech to a handful of its Whole Foods stores by the beginning ofnext year and to eventually expand the super-fast checkout tech to all US locations. The paceof the rollout will depend on how quickly Whole Foods is able to install it and train employees onhow to use it, sources said.
"We don't comment on rumors or speculation," an Amazon spokesperson said.
While a regular card transaction typically takes between three and four seconds, Amazon'snew technology can process the charge in less than 300 milliseconds, a person familiar with theproject said.
"Retailers have always been interested in faster checkout," Majd Maksad, founder and CEO ofStatus Money, a personal finance site, told The Post. "You only have to walk into Whole Foods tosee the massive lines of people waiting to check out. It's a massive friction point."
If successful, the technology also could help encourage consumers to spend more when theyvisit Whole Foods, he said.
"People tend to spend more when they don't have the experience of touching somethingtangible like money," Maksad said. "The utility of money becomes more ephemeral."
At Amazon's budding chain of "Go" convenience stores that launched last year, customers usea phone app to check in at a turnstile. They can then fill their bags and carry them out withoutever passing a register thanks to computer vision and an array of sensors all over the store.
