Description

Technical Field

[0001] The present invention relates to the technical field of card issuing devices, and in particular to a traceable encryption card issuing device based on true random numbers. Background Art

[0002] With the improvement of the degree of digitization, electronic cards with built-in electronic chips have become an indispensable item for people. In various industries such as banking, industry, logistics, and personnel management, in order to facilitate people to handle business, self-service card issuing machines are set up for people to handle card business by themselves. Currently, a card storage box is provided in the card issuing machine to store the cards of users. When a user conducts the business of extracting a card, the card issuing machine needs to take out the card from the card storage box and read the information of the card through an internal card reader to determine whether it is the card of the current user. If the taken-out card is not the card of the current user, the card issuing machine needs to take out the card from the card storage box again and have the card reader read the information of the card until the card matches the current user. The card issuing machine outputs the matching card from the output port of the card reader.

[0003] The existing driving method inside the card issuing machine is generally not direct drive by a motor. During long-term use, the driving structure is prone to jamming. The lifting device inside the existing card issuing machine is driven up and down by one motor, causing the motor to work continuously for a long time, reducing the power and service life of the entire system; due to the repeated reciprocating movement of the card grid box in the existing card issuing machine, sequential high-speed card insertion cannot be achieved; the existing card issuing machine usually has problems of low efficiency, high wear, low reliability, and instability caused by random reciprocating movement. Summary of the Invention

[0064] Working principle of the present invention:

[0065] Place the card deck in the input chamber. The bottommost card is conveyed to the card reading mechanism through the conveying gap formed by the card feeding friction wheel 42 between the lower card feeding friction wheel 40 and the upper card feeding friction wheel 39. Then, the card information is read by the card reader and saved into an array. Subsequently, the card is conveyed into the corresponding card access slot through the upper card reading friction wheel 33 and the lower card reading friction wheel 34. Then, the access component is moved one grid by the first linear driving component and the second linear driving component. A 1-N true random number array is generated by the corresponding program in its controller. Then, the true random number array is bound to the card ID array in sequence. Then, the electromagnetic iron 49 unlocks according to the random numbers in the array from small to large, and then the card drops into the card box 3.

[0066] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
