Systems and methods for detecting potentially compromised payment cards

A token monitoring computing device for detecting potentially compromised payment cards, said computing device comprising one or more processors communicatively coupled to one or more memory devices, said computing device configured to:

• store a plurality of tokens, wherein each token includes merchant identification data corresponding to a first merchant;
• transmit the plurality of tokens to the first merchant;
• receive an authorization request message from a merchant, wherein the authorization request message includes a token and a merchant identifier corresponding to the merchant;
• determine that the received token is one of the plurality of tokens associated with the first merchant;
• determine that the merchant identifier does not correspond to the first merchant;
• transmit a message including instructions to decline the transaction based on the determination that the merchant identifier does not correspond to the first merchant;
• and
• attach a potentially compromised flag to the first merchant based on the determination that the merchant identifier does not correspond to the first merchant, wherein the potentially compromised flag indicates a heightened probability of fraudulent activity.

A computer-readable storage medium having computer-executable instructions embodied thereon, wherein when executed by a token monitoring computing device having at least one processor coupled to at least one memory device, the computer-executable instructions cause the at least one processor to:

• store a plurality of tokens, wherein each token includes merchant identification data corresponding to a first merchant;
• transmit the plurality of tokens to the first merchant;
• receive an authorization request message from a merchant, wherein the authorization request message includes a token and a merchant identifier corresponding to the merchant;
• and
• determine that the received token is one of the plurality of tokens associated with the first merchant;
• determine that the merchant identifier does not correspond to the first merchant;
• transmit a message including instructions to decline the transaction based on the determination that the merchant identifier does not correspond to the first merchant;
• and
• attach a potentially compromised flag to the first merchant based on the determination that the merchant identifier does not correspond to the first merchant, wherein the potentially compromised flag indicates a heightened probability of fraudulent activity.
