Disclosed herein are system, method, and apparatus for detecting a skimmer via a vibration sensor on a transaction card. The method includes receiving, at a server, from a user equipment, vibration information recorded by a transaction card in response to an execution of a transaction at a point-of-service (POS) terminal of a plurality of POS terminals using the transaction card. The vibration information may be recorded by a microphone or an accelerometer on the transaction card while the transaction card is swiped through the POS terminal or inserted into or removed from the POS terminal. The method includes determining, at the server, a state of the POS terminal based on the received vibration information and in response to a determination of the state of the POS being compromised, sending to one or more stakeholders of the transaction a warning message containing the POS terminal information including the POS terminal’s state.

Example embodiments of systems and methods for contactless card verification include a contactless card including a substrate, a processor, and a memory, wherein the memory contains a first applet and a second applet, and a recipient device in data communication with the contactless card, wherein the second applet is configured to retrieve one or more parameters from the first applet via an interface; and wherein the second applet is configured to transmit the one or more parameters to the recipient device for verification.

A user having an account with a payment provider receives an unregistered payment card that is associated with the payment provider, and that includes a magnetic strip encoded with a number unique to the card and a machine readable code such as a QR/barcode embossed thereon. The user may then open an application on the user's mobile device to capture the number associated with the card by, for example, scanning the QR/barcode, capturing an image of the number, speaking the number into the device, or manually entering the number into the user's device. The user may also authenticate with the payment provider by entering login credentials. The user may then confirm a request to link the number of the card with the user's payment provider account, which activates and links the card to the user account so that the user can immediately use the card for purchases.

Various embodiments are generally directed to continuous authentication of a user to a digital service based on activity of a contactless card positioned proximate to a computing device on which the digital service operates. For example, a series of periodic status messages may be provided between a client device and the contactless card to verify whether the contactless card remains active, wherein authorization to access the digital service continues while the contactless card is active, and terminates when the contactless card is inactive.

A system for reprogramming a transaction card may include a reprogrammable microchip transaction card, an account provider system, and a mobile device. A reprogrammable transaction card may include an embedded microprocessor chip, or integrated circuit (IC), housing various modules to provide card capabilities, such as transaction capabilities, security capabilities, and reprogramming capabilities. An account provider system may include a number of servers and computers, each equipped with storage and modules programmed with various capabilities, such as, storing cardholder data, transaction processing, and/or transaction card reprogramming. A user device may include various hardware and software components, such as a Near Field Communication (NFC) hardware and software components, one or more processors, various input/output interfaces, and/or modules, such as transaction processing modules and transaction card resetting modules. Each component of the system may communicate with each other in order to reprogram the transaction card.

A method for registering and activating accounts includes: transmitting a first input from a user regarding opening an account at a financial institution; establishing a communication session based on exchanging encryption keys between the user device and the financial computing system; displaying a graphical user interface (GUI) comprising a request for a user verification; transmitting a received user verification to the financial computing system; updating the GUI to display a request to establish a personal identification number (PIN) for a physical payment card associated with the account; receiving the PIN from the user; transmitting a second input comprising the PIN and a request to provision the account to the user device; receiving a payment token associated with the account before the physical payment card associated with the account of the financial computing system is received by the user; and, storing the payment token for transactions via the user device.

Methods and systems are described for verifying an identity of a user through contextual knowledge-based authentication. The system described uses contextual knowledge-based authentication. By verifying an identity of a user through contextual knowledge-based authentication, the verification is both more secure and more intuitive to the user. For example, by relying on confidential and/or proprietary information, the system may generate verification questions, the answers to which are known only by the user.

A method and system for conducting an online payment transaction through a point of sale device. The method includes receiving input from a user selecting an item for purchase through the point of sale device; calculating a total purchase amount for the item in response to a request from the user to purchase the item; and sending payment authorization for the total purchase amount from the point of sale device to a payment entity, in which the payment authorization is sent to the payment entity via a mobile communication device of the user. The method further includes receiving a result of the payment authorization from the payment entity through the mobile communication device; and completing the payment transaction based on the result of the payment authorization.

An electronic payment card includes a payment card substrate having opposed top and bottom faces. An EMV chip is disposed at a location on one of the top and bottom faces of the payment card substrate. The EMV chip is a donor EMV chip removed from a donor electronic payment card on which the donor EMV chip was previously disposed.
