[0002] At present, ATM machines are widely used in the financial world. People use bank cards on ATM machines that are not "one person, one cabin". Insert another card of the same color as the user's bank card at the entrance of the card reader (magnetic card reader) while the user's sight is away from the ATM, and it is easy to trick the user into taking away the swap card at the entrance of the card reader (magnetic card reader) After paying the user, the criminal uses the user's bank card in the card reader (magnetic card reader) to take away the cash, especially when the elderly and women use the bank card on the ATM machine, the bank card is changed by someone with ulterior motives. Incidents happen from time to time; at the same time, existing ATM machines still exist: when the user forgets to operate the bank card exit button and leaves after using the bank card (leaves without performing the card ejection operation), and the ATM machine is generally set when there is no operation within 30 seconds Therefore, if the bank card that the user stays in the ATM machine card reader (magnetic card reader) is in the transaction interface (the interface entered after entering the correct bank card password) within 30 seconds, the It is easy for others to use this ATM within 30 seconds to take away the money in the bank card that the user stays in the card reader (magnetic card reader) of the ATM
Although looking for a needle in a haystack after the event by checking the video surveillance to find the switcher or latecomer who took away the banknotes and bank cards can only recover property losses for a very small number of users, but it is still nothing for most users. laborious and troublesome

Embodiment Construction
[0031] Such as figure 1 Shown, a kind of ATM machine reduces the method that bank card is switched package, steals, comprises the following steps:
[0032] S100. Set the first timer, the second timer, and the third timer in the central processing unit of the ATM machine, and add a card number temporary storage area, and clear the added card number temporary storage area;
[0033] S200. When there is no card in the card reader, start timing the first timer: within the timing time of the first timer, when a bank card enters the card reader, stop the timing of the first timer, and temporarily store the card number The data in the area is rewritten, and the remaining time of the first timer is set as the timing time of the second timer, otherwise, when the timing time of the first timer is up, the card number temporary storage area is cleared;
[0034] S300. When the central processing unit of the ATM machine reads the bank card number in the card reader, if the card number tempo...

The invention discloses a method for reducing the probability that bank cards are stealthily substituted or stolen for an ATM. The method is characterized in that when a bank card is in a card reader and another bank card is inserted into a card slot, a safety alarm voice prompt is given on site, card retaining operation is conducted on the bank card in the card reader, another bank card inserted into the card slot is controlled to enter the card reader, and accordingly the bank cards are effectively prevented from being stealthily substituted or stolen; after the bank card in the card reader is discharged out or retained, the band card is inserted into the card reader within a limited time, and it is determined that the inserted bank card is a card for stealthy substitution if the card number of the inserted band card is not consistent to the card number of the band card temporarily stored in a temporary storage area: time-limited shielding is conducted on an exit function key of the bank card which is not switched to a transaction interface, remaining balance query function is added for the exit function key of the bank card switched to the transaction interface in a time-limited mode, the sum of limited times of the exit function key is set to be quantitative, and accordingly it is achieved that a user initiatively and independently verify bank card information, the bank cards are prevented from being stealthily substituted, and normal usage of the ATM is also not affected.
