Payment method and system based on 3D holographic projection for identity authentication

The invention discloses a payment method based on 3D holographic projection for identity authentication. The payment method includes that a POS (point of sales) terminal with a 3D holographic projection module is utilized to read an identification code of a payment card of a consumer, a payment order in an electronic form is generated by combining with consuming content and sent to a payment server, the payment server sends the payment order to a cellphone of the consumer for verification, order confirmation information is sent to the payment server after the consumer verifies successfully, the payment server further needs to verify fingerprints of the consumer after receiving the order confirmation information, the payment server returns a consumer 3D holographic image bound with the payment card identification code of the consumer after fingerprint verification succeeds, and the POS terminal projects the 3D holographic image for a merchant to examine and verify identity of the consumer, and the payment server deducts money of an account bound with the payment card of the consumer only after examination and verification succeed. In the payment method, through multistage examination and verification, payment safety is improved greatly.
