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.

Example embodiments of biodegradable cards and systems and methods making the same are provided. A biodegradable card can comprise a biodegradable substrate, a magnetic particle slot within the biodegradable substrate configured to receive magnetic particles, a high coercivity magnetic stripe comprising magnetic particles printed on the biodegradable substrate and encoded with payment account data, and a biodegradable water resistant coating, wherein the coating covers at least the magnetic stripe.

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 method for configuring a Near Field Communication (NFC) smart card, includes: receiving a card selected by a user, the card being included in a card set corresponding to the user; determining at least one card which has no conflict with the selected card in the card set; adding the at least one card and the selected card in the NFC smart card, wherein each card in the NFC smart card is in an activated state.

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.

Embodiments of the present disclosure provide a device, system, methods and components related to a modular card. Example components of the modular card include a thin rectangular rear plate, a thin rectangular front plate overlying the rear plate, a first plurality of fasteners fixed to the thin rectangular front plate, a second plurality of fasteners fixed to the thin rectangular rear plate, the second plurality of fasteners being configured to be removably engaged with the first plurality of fasteners; a magnetic strip, and/or an integrated circuit. In operation a user may remove and/or replace various components to customize the modular card. Some customizations include altering the accounts to which the modular card relates. In some example, the modular card may include components which relate to different accounts.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light input of the light guide.

A process for making a transaction card defined by a plurality of layers is described. The process includes providing a first portion of the card, the first portion comprising a non-plastic layer having first and second faces and a thickness therebetween; forming an opening in the non-plastic layer, the opening defined through the first face; disposing embedded electronics in the opening; providing a second portion of the card; and providing a fill disposed in portions of the opening not occupied by the embedded electronics and attaching the first portion of the card to the second portion of the card.

A physical card may include a substantially planar body that may include a front surface, a back surface, and one or more side surfaces. The front surface may include a background formed primarily in a first color, and a plurality of embossed characters each having one or more front surfaces aligned substantially in parallel relative to the background. The plurality of embossed characters may include one or more side surfaces extending from the background at a lower edge to the front surface at an upper edge, wherein the one or more front surfaces of at least a first embossed character of the plurality of embossed characters are formed primarily in a second color different from the first color and the one or more side surfaces of at least the first embossed character are formed primarily in the first color to limit a viewing angle of the plurality of embossed characters.

Provided herein are systems and methods comprising two or more localization agents that are linked together by a linker. For example, provided herein are systems and methods for the placement of two or more linked localization devices within biological systems and the detection of such localization devices for targeted surgeries or other medical procedures. For example, provided herein are systems comprising one or more miniature detectable devices that are linked together, that are placed into a target location and activated by remote introduction of a magnetic field.
