Description

Technical Field

[0001] The present invention belongs to the technical field of automatic card issuers, and more specifically, relates to an automatic card issuer for supermarkets. Background Art

[0002] In the new retail industry, the trend of convenience in shopping malls and supermarkets has become increasingly prominent. Self-service operations have become more prominent, and convenience, efficiency, and safety are also relatively important. The automatic card issuer technology combines hardware, software, and the network to improve the operational efficiency of supermarkets and the customer experience. Customers can operate through the touch screen, input personal information such as name, mobile phone number, and email, etc., and the machine will immediately generate a membership card and also support sending the electronic card to the mobile phone. For customers who want to cancel their memberships, the card issuer can also be used to recycle the membership card and cancel personal membership information in the shopping mall. The supermarket automatic card issuer technology has broad application prospects by improving efficiency, reducing costs, enhancing the user experience, and data analysis capabilities. With technological progress, the automatic card issuer technology will develop towards the direction of intelligence, integration, and mobility in the future.

[0065] Specifically, the principle of the present invention is as follows: When in use, open the mechanical lock 41, disconnect the magnet 42, and pull open the sliding door 10. The sliding door is opened and closed in a rail-guided manner, and is assisted by a fixed pulley, effectively avoiding the risk of the door body sagging. Place the card in the card slot. There are limits on all four sides, effectively ensuring the orderly arrangement of the cards. After placing the card, press the upper card pressing plate to ensure that the card remains flat in the card slot during the card consumption process, completing the card storage work. If it is not the thickness of a conventional card during the first use, the concave cavity type card adjustment mechanism can be adjusted up and down to ensure that the distance from the bottom is between the thickness of one card and two cards to control the card output of one card each time. After the card storage is completed, close it. There is a magnet 42 at the cabinet door that directly attracts, and the key closes the locking hook of the cabinet door to complete the overall teller card storage operation.

[0066] Put the cards into the card stack. The sensors at the lower and side parts can give early warnings of low cards and missing cards, and feedback to the self-service machine to prompt the clerk to replenish. The scanning component can scan the one-dimensional code or two-dimensional code of the card and transmit it to the self-service machine to complete the card recognition function. The card stack issues cards. The self-service machine conveys instructions. When the card recycling door is in the closed state, the motor drives the pulley to send the card out by friction. After passing through the sensor, it reaches the card nozzle to complete the card issuing.

[0067] At the same time, cards can be recycled and memberships can be cancelled. When recycling a card, the card enters the card nozzle. After being recognized by the sensor, it passes through the scanning component to complete the card code scanning and recognition. The card recycling door opens, and the card enters the recycling box through the restriction of the card door to complete the card recycling.

[0068] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
