A rollable payment card is shiftable between a flat configuration and a rolled configuration via a manual rolling process. The payment card comprises a verification element, a processor, an electronic display unit in communication with the processor, and a power element providing electrical power to the display unit. The electronic display unit includes an electronic display region configured to display an image. The electronic display region is manually rollable. The payment card in the flat configuration presents horizontally spaced apart first and second ends and vertically spaced apart top and bottom edges. The first end overlaps the second end during the course of the rolling process, with the first end being disposed arcuately past the second end when the payment card is in the rolled configuration.

In some implementations, a physical medium may include a radio frequency (RF) component and an integrated circuit (IC) chip component. The physical medium may be configured to detect, via the RF component, that the physical medium is within a communicative proximity of a first user device or a first medium associated with a first account. The physical medium may communicate, via the RF component, with the first user device or the first medium based on detecting that the physical medium is within the communicative proximity of the first user device or the first medium. The physical medium may configure the IC chip component to indicate that the physical medium is paired with the first account. The physical medium may transmit, via the RF component or the IC chip component and to a terminal, an indication that the physical medium is paired with the first account.

Embodiments of the present application provide a method for binding card, a terminal device, an authentication server and a storage medium. The method is applicable to terminal device including security element, and includes: obtaining a user identifier for logging in target application by a user and a secure element identifier of the secure element; sending the user identifier to an authentication server, wherein the user identifier is for the authentication server to search at least one first card bound to the user identifier; receiving card information of at least one first card sent by the authentication server; and sending a binding request to a card issuing server corresponding to card information, wherein the binding request comprises the card information, the user identifier and the secure element identifier, and the binding request is for the card issuing server to bind card information to the user identifier and the secure element identifier.

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.

The disclosed embodiments provide a payment card. The payment card may have a first face and a second face opposite the first. Additionally, the payment card may comprise a first smart chip, the first smart chip having contacts that are electronically accessible from the first face of the card. The payment card may further comprise a first antenna coupled to the first smart chip, the first antenna providing near-field contactless access to the first smart chip and a second smart chip, the second smart chip having contacts that are electronically accessible from the second face of the card. Additionally, the payment card may comprise a second antenna coupled to the second smart chip, the second antenna providing near-field contactless access to the second smart chip and an RF block that electronically isolates the first antenna and the second antenna from each other.

An embodiment server comprises a communicator; and a controller configured to control the communicator, wherein the controller is configured to: in response to receiving connected car service (CCS) subscription information and card information from a vehicle through the communicator, determine whether a card issued to a card integrated circuit (IC) chip of an electronic toll collection system (ETCS) terminal of the vehicle is valid, based on the CCS subscription information and the card information; in response to the card being valid, control the communicator to transmit a normal card confirmation message comprising a security key to the vehicle; and in response to the card being invalid, control the communicator to transmit a card deletion command comprising an authorization key to the vehicle.

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.

In some implementations, a transaction card may receive transaction data from a transaction terminal based on initiation of a transaction with the transaction terminal; generate a tokenized primary account number, for use with the transaction, based on the transaction data and an actual primary account number of the transaction card; and transmit the tokenized primary account number to the transaction terminal for processing the transaction.

There are provided systems and methods for a physical stand for multiple device orientations and peripheral card reader. A device stand may include a dock that allows for placement and securing of a computing device within the device case, such as through a locking or connecting mechanism. The device dock further includes a peripheral component, such as a physical card reader, that allows for reading and entry of card data into the computing device for use with an electronic transaction processing application on the computing device. This allows the computing device to process transactions electronic with an online service provider. Further, the device stand includes a hinge or joint that allows for rotating and inverting of the computing device over a curved extension from a base of the device stand, which allows the computing device to be viewed in multiple directions and orientations.

A method for use with a smart card is provided. The smart card may include a communication interface, a housing, a microprocessor embedded in the housing, a battery for powering the communication interface and the microprocessor, and a nano GPS chip, located within the housing and in electronic communication with the communication interface and the microprocessor. The thickness of the smart card is preferably no greater than 0.8 millimeters (“mm”) and has surface area not greater than 86 mm×54 mm. The method may include determining the location of the smart card in response to a request for a smart card transaction authorization and determining the location of a mobile device associated with a specified user of the smart card. Based on the location of the smart card and the location of the mobile device, the smart card may calculate a location delta between the smart card and the mobile device. If the location delta is greater than or equal to a threshold distance, the smart card may deny the request for smart card transaction authorization.
