Why can t Olympic banknotes pass the money detector?

We tried a few of them today with the bank's money detector, and we really didn't recognize them. The relevant staff of Minsheng Bank admitted that the situation of "the money detector does not recognize the Olympic commemorative banknote" is true. "The main reason is that the anti-counterfeiting points are different. It is reported that the central bank will explain this accordingly in the near future.

Mr. Gu, a citizen, hopes to check the authenticity of the Olympic commemorative banknotes he has obtained. "I deliberately took the Olympic commemorative banknote I had just exchanged to the bank, put it under the money detector and looked, and sure enough, there was an alarm! Mr. Xu, who works in the bank, queued for more than ten hours and finally got the commemorative banknote, but it was really unpleasant to encounter such a thing.

Mr. Gu took the commemorative banknote and carefully studied it with his colleagues, and also took out the 10 yuan banknote in 2005 to compare, and finally discovered the mystery. Compared to the 05 version of the $10 banknote, the commemorative note is longer and wider, and the position of the braille is also different, with the braille of the commemorative note in the lower left corner and the regular banknote in the lower right corner. "The most important thing is that the security points of the two banknotes are different.

According to Mr. Gu and his colleagues, this is the reason why the money detector does not know the Olympic coins.

Ms. Huang, a citizen who changed to the commemorative banknote, didn't care about this, "I won't spend it anyway, and how can the exchange from the People's Bank of China be fake." However, there are also many "lucky" citizens who have received commemorative banknotes, saying that with the circulation of Olympic commemorative banknotes in the coin market, how to identify the authenticity has become a difficult problem. "Anyway, the money detector is unreliable! ”

It's a commemorative coin, and I can't spend it.

The reasons are as follows: First: there is no response when putting money in, which is basically related to the banknote system, either the wire of the sensor is not plugged in well, or the sensor is damaged.

Second: if you don't count the banknotes after counting, either there is a problem with the code disc system or there is a problem with the counting part.

Third: If you can disassemble it yourself, take down the shell, and the plastic parts with money must have burrs and polish them, and it will not be a big problem.

Fourth: It may be that the motor or belt is broken.

Fifth: Maybe the plastic on the shaft is aging, and the dust inside the machine is also related, but don't wipe the oil.

It could be that the motor or belt is broken.

The method I tried has been successfully repaired: first the power was cut off, and I wiped the infrared sensor lamp beads on the bottom plate of the banknote mouth with a cotton swab dipped in alcohol, which is very easy to use now, and there is too much dust! Wipe it clean with alcohol, dry it with a hair dryer and then turn it on, the effect is the same as new, I hope it can help you!
