Amazon is one step closer to implementing its creepy, futuristic flesh-and-blood payment system.

The e-tailing giant’s engineers on Thursday filed a patent application for a device that can scan a human hand — without ever touching it — as a way to ring up a store purchase.

As The Post exclusively reported in September, the device is being developed by Amazon engineers under the code name “Orville” for a future rollout at the Amazon-owned Whole Foods supermarket chain.
