Dynamic triggering of simulated errors in automated teller machines

A computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:

• receive input from a user, the input defining a true personal identification number (PIN) associated with the user and plural different false PINs associated with the user, wherein respective ones of the plural different false PINs associated with the user are associated with respective ones of plural different simulated errors;
• in response to the user initiating a transaction at an automated teller machine (ATM), determine that a PIN associated with the transaction matches a particular one of the plural different false PINs associated with the user;
• and
• cause the ATM to exhibit a particular one of the plural different simulated errors based on the PIN associated with the transaction matching the particular one of the plural different false PINs associated with the user.

A system comprising:

• a processor, one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:
• receive input from a user, the input defining a true personal identification number (PIN) associated with the user and at least one false PIN associated with the user;
• in response to the user initiating a transaction at an automated teller machine (ATM), determine a PIN associated with the transaction matches the at least one false PIN associated with the user;
• and
• based on the determining, cause the ATM to exhibit a simulated error that prevents the transaction and perform one or more security actions in addition to causing the ATM to exhibit the simulated error, wherein the performing one or more security actions comprises one or more of:
• wherein the transaction is a first type of transaction involving an account associated with the user, temporarily disabling a second type of transaction involving the account associated with the user, the second type of transaction being different than the first type of transaction;
• or
• determining a location of the user from a mobile computing device associated with the user, and reporting the location of the user to a predefined contact.
