An example method may include transmitting a noise signal through a reader connection of a magnetic reader element. The control component and the magnetic reader element may be associated with a card reader device of a transaction device, and the magnetic reader element may be configured to read a magnetic strip of a transaction card. The method may include receiving, from the magnetic reader element, a reader connection signal from the reader connection. The reader connection signal may include the noise signal. The method may include extracting, from the reader connection signal, a card information signal associated with the transaction card from the magnetic strip. The card information signal may be extracted based on the noise signal. The method may include performing an action associated with the card information signal.

A system and a method for transmitting payment card information are provided. The system includes at least one memory including computer program code configured to, with at least one processor, cause the system at least to (i) receive, from a capacitive touch sensor, input signals generated in response to conductive elements of a payment card that is placed on the capacitive touch sensor, the conductive elements disposed on the payment card information present on the payment card, (ii) determine, using th e input signals, an orientation of the payment card that is placed on the capacitive touch sensor, (iii) compare the determined orientation with a reference orientation associated with the payment card, (iv) generate computer-readable payment card information based on the input signals on a condition that the determined orientation corresponds to the reference orientation, and (v) transmit the computer-readable payment card information to a payment processor module.

The present disclosure presents a method for a card based transaction between a mobile terminal and a service provider system having one or several computer servers. The mobile terminal obtains (310) a CSC from credit card/debit card. The mobile terminal obtains (320) a data seed. The mobile terminal applies (330) a minimal perfect hash function to the CSC as well as the data seed to generate a temporary CSC. The mobile terminal initiates (340) a card based transaction with the service provider system utilizing the generated temporary CSC. The service provider system obtains (610) the temporary CSC and applies (620) a same minimal perfect hash function to the temporary CSC until a match is found between the obtained temporary CSC and one CSC stored at the service provider system. In response to a match the service provider system continues (630) the initiated card based transaction with the mobile terminal.

A system and computer-implemented method for analyzing chip card transactions to identify defective chip cards and/or defective chip readers in need of replacement. Constraints are established to define a subset of card transactions. From a full set of card transactions the subset is identified consisting of each card transaction falling within the constraints and occurring at a merchant having a chip reader. From this subset the unique chip readers are identified, and for each unique chip reader a percentage of fallback transactions is calculated. The percentage of fallback transactions is compared to a maximum value, and if the percentage of fallback transactions exceeds the maximum value, the chip reader is identified as defective. Each defective chip reader is reported to the merchant, along with at least a recommendation to replace the defective chip reader. A similar process may be used to identify defective chip cards.

A data attack detection system that includes a record host and an orchestration host. The record host stores account information for card holders. The orchestration host includes a switch interface configured to receive transaction information for a card from a network. The orchestration host further includes a velocity trap engine that stores received transaction information for the card in a cardholder file. The velocity trap engine creates entries in a velocity transaction timestamp record for the card when the number of transactions for the card in the cardholder record within a first predetermined time interval exceeds a first activity level threshold. The velocity trap engine discontinues a transaction flow between the orchestration host and the record host for the card when the number of transactions for the card in the velocity transaction timestamp record within a second predetermined time interval exceeds a second activity level threshold.

In some examples, a system and method for activating a payment instrument. The method includes leveraging an activation feature associated with a payment instrument. The representation, obtained by a sensor, of the activation feature is received by the payment processing system. The payment processing system compares the representation of the activation feature with stored activation features corresponding to a user associated with the payment instrument. If the representation matches a user-associated activation feature, the payment processing system activates the payment instrument, wherein activating further includes granting the recipient access to a predetermined amount of funds through the activated payment instrument.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing a plurality of stored fingerprints, wherein each of the stored fingerprints is associated with a respective software environment and a respective mobile device; receiving from a first mobile device a first fingerprint of a first software environment in the first mobile device; determining whether the stored fingerprints include less than a threshold amount of fingerprints identical to the first fingerprint; based on a determination that the stored fingerprints include less than the threshold amount of fingerprints identical to the first fingerprint, determining that the first software environment is a compromised software environment; and performing a corrective measure.

An example method may include transmitting a noise signal through a reader connection of a magnetic reader element. The control component and the magnetic reader element may be associated with a card reader device of a transaction device, and the magnetic reader element may be configured to read a magnetic strip of a transaction card.
