Basic scheme of RFID management of cash box
Using RFID long-distance radio frequency identification technology to monitor and manage the cash box, the basic technical requirements are as follows:
A. Recognition management of outbound and inbound cash boxes.
B.Positioning management of the cash box in the vault area, so that it can quickly reflect its position when it is found and used
C.Counting the amount of the cash box
D. Tracking the cash box of ATM machine, know exactly which ATM machine a certain cash box is on.
The main requirements are A and B, and the extended requirements are C and D
Introduction to RFID technology:
In the application of RFID (electronic tag), the electronic tag is the most advanced identification code at present. It has the characteristics of not easy to break, reliable data, long service life, long effective communication distance, etc. It is an alternative to barcode and infrared identification. Install it on the controlled target to be the unique identification of the target for tracking and positioning. The working principle of RFID automatic identification The system composed of RFID and short-range communication equipment mainly includes smart RFID electrical tags, RFID reading and writing equipment, and wireless communication between the reading and writing equipment and RFID electronic tags to realize the communication between the information management system and the RFID Information exchange.
The read-write device is an RFID read-write controller, which is composed of a microprocessor, a security module, a microwave communication controller, and RS232/485 communication interface. It uses short-range communication protocols and microwave wireless transmission methods to achieve communication with RFID electronic tags. The purpose of safe and reliable information exchange is to connect with the upper computer through RS232/485/wireless/GPRS, and receive control commands and data from the upper computer and return data.
RFID is a mobile device with microwave communication function and information processing and storage functions. RFID built-in a small real-time task system to complete the internal memory, I/O, power supply, communication protocol, key, algorithm, command protocol processing and other functions of the RFID.
The core of the wireless communication protocol adopted by the short-range communication technology is the cell segmentation formed by the coverage of low-power microwave antennas, and the time division multiple access and synchronous communication mechanism based on the HDLC protocol are used to realize reading and writing by designing corresponding processing and control software Two-way data transmission and information exchange between devices.
Based on the above-mentioned introduction to RFID technology, the following basic schemes are specially designed to meet the needs of ATM cash box management.
A.Inbound and outbound management of the cash box
Solution: Install fixed directional readers in front of and behind the door of the vault to connect with the back-end system.Equipped with relevant cash boxes separatelyRFIDElectronic tags are used to determine the entry and exit of the library based on the smoothness of the first hand who has read the information. Automatically save to the background system.
B. For regional positioning requirements in the vault, we provide two solutions:
Plan 1. Equipped with each cash boxRFIDElectronic tags correspond to unique ID numbers respectively. Install the reader in front of a certain designated area in the vault, and install shielding materials around this positioning area. Prevent readers in other areas near it from reading the cash box ID number of this fixed-point unit. And to monitor the ID number of the cash box in this area from time to time. Relevant information is transmitted to the background through wired or wireless means. If you use wireless WIFI for transmission, you need to deploy a wireless domain network in the vault. When a cash box needs to be found or used, the location information is directly obtained through the background. Disadvantages: There are many equipment to be deployed, the cost is relatively high, and the impact of environmental factors on wireless transmission must be considered.
Solution 2. Each cash box is equipped with RFID electronic tags, which correspond to unique ID numbers. Use handheld RFID devices (CF reader cards and PDAs) to detect cash drawers equipped with RFID tags. The handheld devices are pre-loaded with the ID numbers (1 or more) of the cash drawers that need to be searched through the software. When the handheld device is close to the cash box that needs to be searched and reads its ID number, it will automatically sound a reminder. The staff can find the cash box that meets the demand in this area. This scheme is flexible and simple, and does not require complicated changes to the vault.
RFIDHandheld
C. Counting the amount of the cash drawer for expansion
RFID read-write electronic tags, storage space options (1K 4K 8K), each cash box is equipped with a unique ID number. Use the reader (handheld or fixed) to write the relevant amount (or destination, or time, etc.). When the ID number is re-identified by the reader (as reflected in Scheme A, the read-write device installed at the door of the vault can obtain the information in the relevant cash box, such as the amount, etc., while reading the in and out of the vault), Feedback to the background for a time. This electronic tag can be repeatedly erased and used for multiple times.
Expansion requirements D. Tracking ATM cash box, know exactly which ATM a cash box is on.
The cash box used in the ATM machine has been equipped with electronic tags
Solution: 1. ATM has a built-in reader, which is connected with the PC in the ATM. When the signal of the cash drawer is recognized, it is transmitted to the control center through the internal network.
The company’s main business is 2.4G long-distance readers and various active electronic tags in the field of radio frequency identification.The product adopts the most advanced 0.18uM microwave chip technology, which makes RFID Compared with the original microwave technology, its performance has been substantially improved, and it has completely solved the identification and data transmission problems of long-distance, large-flow, ultra-low-power, high-speed moving markers, and the cost is greatly reduced compared with the past. It solves the fatal weakness of low frequency electromagnetic wave technology with short induction distance and poor anti-collision ability. Its various technical indicators are superior among similar products, and are widely used in long-distance identification of various personnel, vehicles and assets, all-in-one card consumption, anti-counterfeiting and anti-theft, real-time monitoring, tracking and positioning, etc.
