Self-service vending machine based on NFC convenient payment

Abstract

The invention relates to the technical field of NFC payment, and discloses a self-service vending machine based on NFC convenient payment. The vending machine comprises a rack, a support plate is fixedly connected to the interior of the rack, a swing plate is movably connected to the outer side of the support plate, a worm is fixedly connected to the top of the support plate, a sliding rod is slidably connected to the interior of a top plate, a driving rod is movably connected to the right side of the sliding rod, a suction block is slidably connected to the interior of the rack, a friction block is slidably connected to the right side of the suction block, an air cavity is formed in the inner wall of the rack, a piston rod is slidably connected to the interior of the air cavity, and a piston plate is movably connected to the outer side of the piston rod. According to the self-service vending machine based on NFC convenient payment, a driving wheel rotates to drive a magnetic block torotate, the magnetic block drives a suction block to move, the suction block rubs with a friction block, the friction block increases the air pressure in an air cavity, the air pressure drives a piston rod to rise, and then the piston rod and a bottom plate are matched for use, so that the effect of convenient card taking is achieved.

Description

technical field [0001] The invention relates to the technical field of NFC payment, in particular to a self-service vending machine based on NFC convenient payment. Background technique [0002] NFC is near-field communication, which is a short-distance high-frequency wireless communication technology. Devices using NFC technology can exchange data when they are close to each other. NFC payment means that consumers use NFC immediately when purchasing goods or services. It is an emerging mobile payment method that completes payment through handheld devices such as mobile phones. Most self-service vending machines on the market support NFC payment. [0003] The existing self-service vending machines with NFC payment cannot prevent electromagnetic interference when using NFC payment. When the surrounding electromagnetic field is strong, it will cause payment failure and affect the use of the equipment. At the same time, when using a card for NFC payment, the card is not easy to...
