Why can’t you spend the money for consecutive numbers (why kidnappers and robbers don’t want the money for consecutive numbers)

Careful friends will often notice such a detail: in film and television works, kidnappers and robbers will refuse to accept new banknotes with consecutive numbers. What is going on?

In fact, although most of the plots in film and television works are fabricated, it is easy to get caught using new banknotes with serial numbers. This plot is reliable.

Why is this?

New banknotes with serial numbers

Banknotes are issued from the banknote printing factory, and the serial numbers of the batches are registered in detail. Which batch of numbers is sent to which bank and where it is used. All circulation is registered. In the future, if these banknotes appear in places they should not appear, or if the serial numbered cash involved in the case suddenly appears, the police can use the serial number records to find out the approximate circulation channel, and then follow the clues to capture the suspect.

The only source of large sums of money with serial numbers is from banks. Now is the high-tech era, the circulation of funds is very convenient, and there is no need to withdraw large sums of cash in daily life. Even if there are special circumstances and a huge amount of cash needs to be withdrawn, the bank will inquire about the purpose and keep very detailed records of the withdrawal and flow of the money. In addition, all cash circulating in the bank will automatically record its serial number, so huge amounts of serial cash have been locked since they left the bank's hands.

Of course, the circulation of a banknote generally does not attract attention. If a new banknote with a serial number appears in a place where it should not appear, it is an important clue for the police to solve the case. The reason is very simple. When new banknotes leave the factory, they are all serially numbered. Once they enter circulation, the connected numbers will soon be dispersed. In other words, the appearance of new banknotes with serial numbers in a certain place means that these banknotes have just been taken out from the bank and have not been circulated. It is very easy to find out its circulation channels.
