Description

A seal card counting device suitable for batch loading and counting and its counting method

technical field

The present application relates to the field of signature cards, and in particular, to a signature card inventory device suitable for batch loading and an inventory method thereof.

Background technique

The signature card is an important means of controlling payment risks in the management method of RMB settlement accounts, and plays a pivotal role in the account transactions between banks and enterprises.

Taking a check as an example, the general process for an entity to conduct a cheque business through a bank is as follows: an account opening entity first needs to apply for an account opening at the bank, and the bank makes and keeps a signature card affixed with the company's seal, which is usually called a reserved signature card. ; When the account-opening unit goes to the bank for check business, the account-opening unit issues a check with its own unit seal, and the bank compares the similarity between the unit seal affixed on the check and the unit seal affixed on the reserved seal card. Thereby, the authenticity of the unit seal stamped on the check is judged, and only when the judgment result is true, the bank will carry out the relevant check business for the unit.

In the prior art, since the number of units applying for opening an account in the bank is huge, the number of reserved signature cards kept by the bank is very large. How to realize the effective management of a huge number of signature cards has always been a difficult problem in the banking business at this stage.

In patent CN108477865A, the applicant disclosed a signature card cabinet and an automatic counting method for signature cards. As shown in FIG. 1 , the signature card cabinet includes nine layers of rotating components, and each layer of the rotating components includes a disc-shaped carrier plate 52 that rotates around a fixed axis 51 in the center. On the carrying tray 52 of each layer, a circle of guide rails 53 arranged in the radial direction are evenly arranged in the circumferential direction, and a drawer box 54 (or called a signature card box) is slidably fitted on each of the guide rails 53 (eg Fig. 2), a drawer box 54 usually stores several signature cards 55 (as shown in Fig. 3), and each signature card 55 is affixed with an RFID electronic label 506. As shown in FIG. 4 and FIG. 5 , nine RFID radio frequency antennas 56 are alternately distributed on the side of each layer of the carrier plate 52 , and two four-channel UHF readers 57 are installed at the same time. When the nine-layer rotary assembly rotates, the drawer box 54 and the signature card 55 also rotate, and the RFID radio frequency antenna 56 on each layer can receive the information on the signature card 55 in the corresponding drawer box 54 on each layer at any time, and feed it back to the four-channel The UHF reader/writer 57 and the four-channel UHF reader/writer 57 identify the label information of the RFID electronic tag 56 on the signature card 55, and read and write the label information on the signature card 55, so that the entire signature can be monitored. The flow of all signature cards in the card cabinet can determine the access status of signature cards and realize automatic inventory function.

However, the automatic inventory in the above application and the automatic inventory in the prior art are to scan all the signature cards in the entire signature card cabinet by starting the RFID radio frequency antenna after the signature cards are all loaded and cast, to obtain the RFID electronic signature of the signature card. The storage information recorded in the label is an after-the-fact check, which needs to be counted within a set time period. It cannot be done at the same time when the signature card is loaded and the signature card is checked, and the counting is time-consuming and has low accuracy. Once any leakage is found The inspection situation requires subsequent manual search and processing, and the work intensity is high. With the doubling of the number of signature cards stored by banks at this stage, the previous management and inventory methods have low timeliness, reliability and controllability, which can no longer meet the actual needs of the bank's daily management process, especially the batch installation and investment. When the signature card is used, real-time inventory cannot be realized, which brings a lot of inconvenience to the centralized management of the signature card.

Therefore, the existing technology still needs to be improved and developed.
