Systems for contactless authentication and event processing are provided. In some examples, functionality of a self-service kiosk may be requested. In response, a user may be authenticated and a first interactive user interface may be generated and displayed by the self-service kiosk. A second, different interactive user interface may be generated and transmitted for display by an event processing device. A user may select an option displayed by the event processing device. The user selection may be made via the second interactive user interface. The user selection may then cause the self-service kiosk to execute the selected function.

A credit card with an obscurable account identifier. The credit card further comprises a substrate defining a first surface with a chromogenic feature wherein the chromogenic feature is capable of changing from a first state and a second state based on an activating trigger. In the first state, the chromogenic feature appears with a first optical property that obscures the account identifier, and in the second state, the chromogenic feature appears with a second optical property that reveals the account identifier.

A method implemented in an electronic entity capable of implementing a plurality of applications includes the following steps: detecting an electrical signal (D; D′); reading, in a memory of the electronic entity, information relating, among the plurality of applications, to a previously selected application; and transmitting a command (CMD) to deliver an indication associated with the application to which the read information relates. An associated electronic entity is also described.

A communication device for sensing one or more biometric characteristics of a user. The device includes a cover structure, a layer of output pixel elements, a layer of biometric input pixel elements, and a processor. The cover structure includes an exterior surface. The layer of output pixel elements is positioned below the exterior surface and configured to provide an output through the exterior surface toward the user. The output pixel elements being at least one of light emitting pixel elements and piezoelectric-out pixel elements. The layer of biometric input pixel elements is positioned below the exterior surface to receive a reflected biometric input passing from the user through the exterior surface. The biometric input pixel elements being at least one of light detecting and piezoelectric-in pixel elements. The processor is connected to the biometric input pixel elements to process the reflected biometric input.

Implementations of a smart card comprising a single smart card for multiple uses which has a number of separate areas that are accessed by one code are provided.

Provided are compact transaction cards. In some approaches, a body of the card includes first and second sections rotatably coupled together, wherein the first and second sections define a first main side opposite a second main side, an insertion end perimeter opposite a second end perimeter, and a first side perimeter opposite a second side perimeter. The body may include a chip along the first main side, the chip being located on the first section of the body. A magnetic stripe may be provided along the second main side of the body, wherein the magnetic stripe is located on the second section, wherein the magnetic stripe extends parallel to the insertion end perimeter when the first and second sections are in a first configuration, and wherein the magnetic stripe extends perpendicular to the insertion end perimeter when the first and second sections are in a second configuration.

Provided are compact transaction cards. In some approaches, a transaction card may include a body having first and second main sides, a first and second end perimeter perimeters, and first and second side perimeters, wherein a first axis extending between the first and second side perimeters defines a first section of the body and a second section of the body. The card may further include an identification chip along the first main side and a magnetic stripe along the second main side, wherein the magnetic stripe extends between the first and second side perimeters, and wherein the magnetic stripe and the identification chip are located on the first section of the body. The card may further include a textured grip along at least one of the first main side and the second main side, wherein the textured grip is positioned only on the second section of the body.

A transaction card includes an anodized card body having a front and rear face. Various information and security features may be provided on the front face and on the rear face. A magnetic stripe may be provided on the rear face of the anodized card body. The magnetic stripe may be adhered within a slot formed within the rear face of the anodized body. Alternatively, the magnetic stripe may be provided via an overlay that is adhered to the rear face of the anodized body, and the magnetic stripe may be integral with the overlay or adhered to the overlay after the overlay is applied to the anodized card body. The transaction card may also include a hologram. The hologram may be integral with the overlay or may be applied to the overlay that has been arranged on the anodized card body.

An circuit includes a first inductive coil and a second inductive coil each including a plurality of metal traces. The first and second inductive coils are each configured to receive a first signal from an electromagnetic field and generate respective first and second output voltages. Each of the first inductive coil and the second inductive coil are configured to inductively couple to the electromagnetic field. A first circuit element is configured to receive the first output voltage and generate a first response at a first power level of the first output voltage. A second circuit element is configured to receive the second output voltage and transition to an active state to perform one or more functions when the second output voltage exceeds a second power level. The first and second power levels are related to movement of the first and second inductive coils through the electromagnetic field.

Aspects described herein may allow for a payment card assembly including a payment card having a first surface and an opposed second surface, and being formed of a biodegradable plastic. A Europay, Mastercard, and Visa (EMV) chip may be removably secured to the payment card. One or more plant seeds may be embedded in the payment card.
