President Xu clasped his hands with each other, probably not used to Hu Zongren's approach of me and going straight to the point from the beginning, maybe in the past she had to be polite to the visiting guests before talking about business. President Xu was silent for a while and said, "Here's what happened."

About two or three days ago, they received a complaint from a customer at the front desk that the ATM seemed to have a problem and often made its own noise for no apparent reason. At first, when we received the complaint, we thought that the money counting system in the machine would regularly count the banknotes in the machine, so we explained to the customer, but the customer said that this was not the case, but made the sound as if he was entering a password. And the reason why he wanted to complain was because he was withdrawing money at the ATM at the time, and he obviously didn't touch the machine, but when he entered the withdrawal amount, he popped up a strange withdrawal amount, 260 yuan, and pressed OK, and the reason why he didn't spit out the money was entirely because the ATM did not support a denomination like 60 yuan. The customer who complained said that he felt very strange at the time, and he repeated the operation several times, and he saw that the situation was wrong, and he was afraid that the card would be locked, so he pressed the button to return the card, and then changed to an ATM. That's when the money was taken out.

Despite this, this guest still thinks that this is unreasonable, if he happens to have a lot of money on his card, then he will not withdraw money arbitrarily because of the failure of the machine? And it's hard to say whether it's caused by the virus or not, what if your bank card information is stolen like this, and it's not like nothing like this hasn't happened. But at that time, after the customer complained, we also went to check the machine on the spot, there was no fault at all, we proposed that if the customer has a difference of opinion on our handling, we can help him apply for access to the bank's monitoring route, but he may feel troublesome, so he just gave up, anyway, his money has not decreased, so it is better to have more than one thing. This matter is over, and no one cares about it, because we receive complaints from customers every day for different reasons, and this kind of complaint seems to us to be completely unreasonable, so no one cares.

President Xu continued, but in the afternoon of the same day, another guest suddenly scolded a few words when withdrawing money, saying that what is going on with your machine, you can't afford to press it, and you still have to remind you if there is a fault! President Xu said that the security guard in the hall on the first floor of our first floor heard the sound of the past, but our security guard was not a technical technician after all, so he simply explained, and asked the guest to change a machine to withdraw money, but this time the security master reported the situation directly to the people in our office, and there were two such situations in the same day, and there was no way to find out the reason, so we immediately notified the technical technician to suspend the use of this machine.

President Xu told us that ATMs have greatly alleviated the workload of counter staff in some aspects, so even after we reported the malfunction, we would quickly send someone to deal with it, but through inspection, we found that there was no problem, and we even considered whether it would be due to poor key contact, but it was not. The maintenance staff said that the machine was in good condition and did not need to be repaired at all, so it could be used again. Since he said so, we laymen can only follow the faith. However, when the machine was restored, we specifically told the security guard on the first floor to report any problems immediately.

President Xu said that everything was normal that day, and the people who came later to withdraw money and save money on this machine did not encounter any problems. But the next day, the machine had a problem again, but this time the problem was different from the previous day, and it was not possible to insert the card. President Xu paused and said, to be precise, it was not that it could not be inserted, but that after inserting it, it was spit out for no reason before it could be operated. Some of the guests who are not so concerned about it after seeing, most of them can change a machine to withdraw money, as if there is no such thing, but there are always a few more serious guests will tell our security guards, the machine is broken, and now it is still spitting cards, maybe if you don't repair it, you will start to swallow the card. Because I had greeted him in advance, our security comrade was also very responsible, he immediately reported this matter to us, and I personally went down to see it, I not only watched but also went up to operate it myself, and I really just inserted the card in, and before I had time to enter the password, I automatically spit out my card, and the strangest time, at this time, the ATM machine screen also displayed please enter the password. Hu Zongren asked President Xu in wonder, what does that mean? President Xu said that it means that the card is not spit out by the system, just like you take a wire and insert the card into it, and then pull it out again. Hu Zongren sighed and said to President Xu that this is okay, and I will try to do it in the future. President Xu shook his head and said, that is basically impossible, because the size of the card slot is completely suitable for the design, and if someone really uses iron wire or steel wire to pull the card out, we will have an alarm device. President Xu went on to say that the blame was that the card came out, but the alarm was not triggered, and even the machine itself did not reflect the fact that the card had been spit out.

President Xu went on to say, so when I saw this situation that day, I immediately felt that the maintenance worker who came to repair the machine the first day was too unconscionable, so I immediately stopped using the machine, and immediately called the other party to send someone to repair it, and not to send the maintenance personnel from yesterday. After more than half an hour, the other party came, but the results after the boot check turned out to be consistent with what the maintenance worker said before, the machine did not have any faults, if you insist on saying that there is a problem, at most it is a matter of speed. Even if the worker explained so, but President Xu they always thought it was unacceptable, when the two sides argued, President Xu took out his card again, and demonstrated it on the spot, and this time, the card was used very smoothly, and there was no random numbering, or spit out the card.

President Xu told us that it was his turn to be embarrassed at that time, but the other party still told us that if we were really not at ease, we would suspend the use of it, and we would update the computer host again in a few days, perhaps caused by the long boot time. Before the maintenance worker left, he turned off the main power supply of the machine and put a piece of paper on the screen with the words "Under maintenance, suspended, very sorry".

President Xu said, it just so happens that the security guard is on duty that night, usually we will leave the security guard in the office area at night, you go upstairs to see it, the ATM machine belongs to the open area, it is 24 hours can enter, but after 10 o'clock at night, you need to swipe the card to be able to enter, there is an isolation door between the office area and the ATM, and the security master is in the office area at night. After the bank closes, the power will be cut off, so if the security guard is on duty at night, he can only play with his mobile phone at most. But when it was about 12 o'clock at night, the electronic door of the ATM suddenly opened, and the security guard thought that someone was coming to withdraw money. But after a while, I didn't hear anyone withdrawing money, but heard a long "————" sound.

President Xu told us that the sound was very familiar to our security guard, which was the sound made when the ATM machine was just turned on, and the money counting system needed to be activated due to some principle. But the security guard thought to himself, the few machines over there, except for the faulty one, are all on, and the lights are still on, and there is no power outage. So how did that sound appear, when he thought of this, the security master got up and planned to take a look, but through the grid on the isolation door, he saw that there was no one over there, so he changed the angle to see if the broken machine started on its own, and it was like this, not only started, but also seemed to be operating in general, making a "Di Di Di" button sound.

Xu Xingchang went on to say that since he couldn't see the main part of the screen, he didn't know how the sound came from, but soon the sound stopped, but the machine was still on. Then the electronic sensor door suddenly opened at this time, but there was no one inside or outside. While the security guard was wondering what was going on, the lights in the ATM area suddenly began to flicker, and after a few flashes, the whole thing went out.

President Xu looked a little nervous and said, Originally, the bank was not a big place, and the power outage was normal, but after the power was cut off, the ATM machine was not powered off, and in the originally dark environment, the blue light on the screen of the ATM machine closest to the security guard was reflected, and he saw a very short figure, some like children, but because there was no light, he couldn't see clearly.

That scared our security guard miserably, he took a few steps back, and took out his flashlight to shine, but at this time he found that there was nothing, and when he didn't understand what to do, the electronic sensor door suddenly opened again, and when it was closed, the light turned on again. Hu Zongren asked President Xu, didn't he say that the power was cut off? Why do ATMs and electronic gates still work? President Xu said that the ATM machine line is different from that in our bank, and there is an emergency power supply system, and the electronic door does not know what the road is.

President Xu said that maybe it was because there was no power outage at all, but the lights were affected by something and were temporarily cut off.
