Systems and methods for data desensitization

Abstract:

Systems and methods are provided to identify payment data and desensitize the payment data by a secure card reader. Desensitization of the payment data may include replacing sensitive information such as discretionary data with zeroes or other predetermined values. Desensitization may also include replacing sensitive information with fraud detection data such as merchant identifying information. Desensitization of the payment data may leave certain payment data intact for customer tracking or other non-payment related purposes.
