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.

A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.

Approaches herein provide a transaction card including an interchangeable ID chip. In some approaches, a transaction card may include a body having a first main side opposite a second main side, a first side opposite a second side, and a first end opposite a second end. The transaction card may further include an insert extending within a cutout section of the body, wherein the cutout section extends towards a center of the body from the first side or the second side, and wherein the insert includes an identification chip.

A collision activated RFID recorder for a vehicle having an RFID reader/recorder, the RFID reader/recorder has a transceiver. A transceiver has a receiver capable of receiving signals and a transmitter capable of sending signals. A collision activated RFID reader/recorder is in electrical communication with memory. Imported data may be stored in the memory of the activated RFID reader/recorder. The collision activated RFID reader/recorder has a collision sensor configured to be mounted on a vehicle. The collision sensor has an antenna configured to transmit an activation signal to the transceiver of the RFID reader/recorder, whereby, said collision sensor detects a collision, generates said activation signal, and then transmits the activation signal to the transceiver of said radio-frequency identification recorder. The RFID reader/recorder is configured to be activated when the transceiver of the RFID reader/recorder receives the activation signal from the collision sensor.

Metal transaction cards with removable indicia are provided. In some approaches, a transaction card may include a metal body having a first main side and a second main side, and an identification chip coupled to the first main side of the metal body. The transaction card may further include an exterior layer along the second main side, the exterior layer containing identifying indicia, wherein at least a portion of the exterior layer is removable from the second main side by at least one of: a set of perforations through the exterior layer, and a channel provided along an outer edge of the second main side.

A flexible card may include a dynamic magnetic stripe communications device having multiple layers, such as an electromagnetic generator, a magnet, and a shield. A shield may form a non-flexible layer within the stack and may bend, but the shield may not be able to stretch or compress. Flexible layers may surround and adhere to the shield such that when the card is flexed, the flexible layers may stretch and compress with the movement of the shield. The dynamic magnetic stripe communications device may include one or more coils. Each coil may contain a stepped material, such that a length of a lower layer of the stepped material is longer than a length of a middle layer of the stepped material which is longer than a length of a top layer of the stepped material.

The present invention describes a tag comprising a magnetic element in the form of a microwire of 80-250 microns with giant magnetoimpedance which, when joined to an object, allows for the wireless detection of same by modulating the reflectivity of the microwire. Detection is performed by using a system that emits an electromagnetic wave that has a frequency between 1 and 20 GHz and a low frequency magnetic field (0.01-50 Hz), and detects the modulation of the reflectivity of the microwire. Thus, objects at distances greater than 1 m can be detected.

A mobile card reader can be configured to connect to an input module of a mobile device. The mobile card reader can scan a magnetic stripe card from a structure exposed to lightning strikes in order to output a lightning-indicator signal to the input module. The lightning-indicator signal can be analyzed to determine a magnitude of a lightning strike to which the magnetic stripe card and the structure have been exposed.

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.
