Systems and methods for temporarily activating a payment account for fraud prevention

A computer-implemented method for temporarily enabling an otherwise disabled payment account for use in a transaction, the method comprising:

• receiving, from a point of sale device, a transaction request associated with an account of a user, the transaction request comprising a transaction value representing a currency amount;
• determining that the user account has a disabled status;
• determining that the transaction value matches a stored authorization code associated with the user account;
• based on the determination that the transaction value matches the stored authorization code associated with the user account, modifying the disabled status to permit successful processing of at least one subsequent transaction request associated with the user account;
• receiving, from the point of sale device, the at least one subsequent transaction request, the at least one subsequent transaction request comprising a subsequent transaction value representing a currency amount;
• converting the at least one subsequent transaction request into a service request code based at least in part on the subsequent transaction value;
• determining an associated service request based on the service request code and a predetermined look-up table, the look-up table being specific to a geographic region determined by geographical data in the at least one subsequent transaction request;
• and
• authorizing the associated service request.

A non-transitory computer-readable medium storing instructions executable by a processor to cause the processor to perform operations for temporarily enabling an otherwise disabled payment account for use in a transaction, the operations comprising:

• receiving, from a point of sale device, a transaction request associated with an account of a user, the transaction request comprising a transaction value representing a currency amount;
• determining that the user account has a disabled status;
• converting the transaction request into a personal identification code based at least in part on the transaction value;
• determining that the personal identification code matches a stored authorization code associated with the user account;
• based on the determination that the personal identification code matches the stored authorization code associated with the user account, modifying the disabled status to permit successful processing of at least one subsequent transaction request associated with the user account;
• receiving, from the point of sale device, the at least one subsequent transaction request, the at least one subsequent transaction request comprising a subsequent transaction value representing a currency amount;
• converting the at least one subsequent transaction request into a service request code based at least in part on the subsequent transaction value;
• determining an associated service request based on the service request code and a predetermined look-up table, the look-up table being specific to a geographic region determined by geographical data in the at least one subsequent transaction request;
• and
• authorizing the associated service request.
