Note: ATM and CDM used by commercial banks in China are mainly produced in Germany and Japan. ATM self-help cash machines are also upgraded from old-fashioned machines to new machines and CDM self-help cash machines to CDT, replace it with the CRS self-help deposit and withdrawal machine!
Currently, the most advanced machines in the market are crs4000 self-help deposit and withdrawal machine and ATM self-help machine ~~~
This post uses the crs4000 self-help deposit and withdrawal machine as an example to describe how it works. ATM and CDM are basically the same!
The crs4000 self-help deposit and withdrawal machine is divided into two layers. The upper layer is the card plug-in port, the exit port, the banknote port, the bank's flow account and the customer's receipt, and the deposit and money check are also on the upper layer. The lower layer is the safe, there are five cash boxes in the safe!
Before using the crs4000 self-help deposit and withdrawal machine, first check whether the screen is normal. If the screen is black and there is no sound on the buttons, the machine is stopped (Disabled). If the screen is black and the buttons have sound, if the screen is broken, you can also do business at this time, but the screen is black and cannot follow the on-screen prompts, the veteran can operate, and others will not operate! If the screen shows <the service is suspended on the local machine>, the first is that the machine network is disconnected, the second is that the printing paper of the bank account is used up, and the third is that the banknotes in the machine are out of order, resulting in money congestion, in either of the three cases, <the service is suspended on the local machine> and no business can be performed. The administrator must repair the service! If the screen shows normal, after a debit card or credit card is inserted, there is no functional film block for deposit and withdrawal. One is that the banknotes in the machine are disordered, and the other is that there is no money in the machine, in either case, there will be no functional film block for deposit and withdrawal, and the administrator needs to repair or add money!
Understanding withdrawal and deposit limit: According to the People's Bank of China, the Daily withdrawal limit of each card in the ATM is 20 thousand yuan, and the maximum amount of a single withdrawal is determined by each bank, which is generally 3 thousand or 5 thousand yuan; the deposit limit is less than 200 (100 yuan or 50 yuan or 100 yuan!
Understand the denominations of banknotes that crs4000 self-help deposit machines can provide and the denominations of banknotes accepted: the self-help withdrawals of crs4000 are the same as normal ATM cash machines, and only 100 yuan of denomination banknotes are provided, however, ordinary ATM machines can not only provide 100 yuan denomination banknotes, but some also provide 50 yuan denomination banknotes or even 10 yuan denomination banknotes! Therefore, before using an ATM, you must know what kinds of bills your ATM can provide! The crs4000 self-help deposit is the same as that of a General CDM cash machine. The crs4000 and 50 RMB bills are accepted, however, the crs4000 self-help cash machine can accept 200 or less 100 yuan or 50 yuan of two kinds of denomination banknotes at a time (the two types of denomination banknotes can also be mixed together and automatically recognized by the machine, but no more than 200 images), and the recognition speed is very fast, reaching 8 images/second, which is not suitable for general CDM cash machines! Ordinary CDM deposit machines accept 100 yuan and 50 yuan of cash, but only one deposit can be made, one for every 15 or less. After the deposit is successful, the next deposit will be made, multiple storage is not limited! CDT deposit machines can accept up to 30 yuan or 50 yuan worth of cash at a time, much faster than CDM deposit machines, however, crs4000 self-help cash registers still seem inferior!

Crs4000 self-help deposit machines, the self-help withdrawals do not have the money-checking function, and ordinary ATM machines do not have the money-checking function. That is to say, what is the money that a bank puts in, and what is the customer taking out, this requires the bank staff to have a high degree of responsibility to the customer, to close the well-installed currency, and put an end to ** loading the machine, so as to avoid losses to the customer and adversely affect the bank's reputation!

Crs4000 self-help deposit machine, the self-help deposit part has the banknote checking function, the general CDM cash machine and the CDT cash machine also has the money checking function, but the crs4000 self-help deposit machine self-help deposit part of the money checking function is more advanced! The crs4000 self-help deposit teller machine money detector consists of two parts: one is fixed memory, and the other is money detector!
The money detector is composed of a touch glass with a length equal to that of a banknote and a width of 3CM. When a banknote passes through the money detector, the concave and convex pixels on the banknote are sensed when it passes through the money detector, and arranged by a matrix circuit, A sensor pixel is formed, and then compared with the pre-stored pixel in the fixed storage to reach more than 95 percent, it is considered as a real banknote, and then a RMB renewal or 50 RMB renewal channel is started, enter the computers separately!

Note: Because self-help deposits have the banknote checking function and the pixel points must be more than 95 percent, this requires that the banknotes be kept clean and tidy and free of dirt and folding! If the corner of a banknote's thumb is folded, 20 thousand pixels will be lost. Thousands of pixels will be lost for the dirt of a grain of rice, and the pixels will be lost for other reasons, your money may not be recognized and returned by the self-help cash machine!

Sometimes, a normal banknote is not recognized and returned by a self-help cash machine. This is a large area of dirt. Although it is not noticed by the human eye, the banknote inspection function can recognize it, at this time, you can change a plane or call a header to try again. Generally, the operation can be successful. If it fails three times, don't try again!
