A transaction card is provided for communicating data relating to a transaction. The transaction card includes a solar layer, a transaction card layer, and a power transfer layer. The solar layer includes at least one solar panel capable of converting light into electricity, the transaction card layer supports the solar layer and includes a magnetic strip, and the power transfer layer includes circuitry capable of receiving electricity from the solar layer.

Systems and methods are provided for use in provisioning digital identities for users. One exemplary method includes receiving, at a card device, an authentication request and a captured first biometric of a user, from a communication device associated with the user, and comparing the first biometric and a first biometric reference at the card device, in response to the first biometric reference being stored at the card device. The method also includes capturing, at the card device, a second biometric of the user and comparing the second biometric to a second biometric reference stored at the card device. The method further includes compiling a response to the authentication request including a first indicator of the comparison of the first biometric to the first biometric reference and a second indicator of the comparison of the second biometric to the second biometric reference, and transmitting the response to the communication device.

A method and system for communicating estimated blood loss parameters of a patient to a user, the method comprising: receiving data representative of an image, of a fluid receiver; automatically detecting a region within the image associated with a volume of fluid received at the fluid receiver, the volume of fluid including a blood component; calculating an estimated amount of the blood component present in the volume of fluid based upon a color parameter represented in the region, and determining a bias error associated with the estimated amount of the blood component; updating an analysis of an aggregate amount of the blood component and an aggregate bias error associated with blood loss of the patient, based upon the estimated amount of the blood component and the bias error; and providing information from the analysis of the aggregate amount of the blood component and the aggregate bias error, to the user.

A method for removing an EMV chip from a plastic credit card or debit card and placing the removed EMV chip onto a metal card, includes heating the plastic credit or debit card containing the EMV chip to loosen the EMV chip, the EMV chip being substantially square and planar, the EMV chip having an upward top face, a downward bottom face, and four sides; removing the loosened EMV chip from the plastic credit or debit card; bending the four sides of the EMV chip towards the downward bottom face of the EMV chip; applying an adhesive coating to the bottom face and the bended four sides of the EMV chip; and placing the adhesive coated bottom face and bended four sides of the EMV chip into a holding cavity of the metal card.

Aspects described herein may allow for prompting a user to access an on-line tool to create an identification element to be added to an exterior surface of a personal card. A server device may prompt the user to select a location for the identification element from a plurality of pre-selected locations on the personal card, each of the plurality of pre-selected locations being proximate edges of the personal card and outward of any of magnetic strips, chips, text, photos, and images on the personal card. The server device may modify an exterior surface of the personal card to include the identification element at the selected location, and deliver the personal card to the user.

There is provided a card or token for use in financial transactions. The financial transaction token or card has an onboard energy storage device that enables onboard electronics to operate when the card is not in the proximity of a merchant Point-Of-Service (POS) terminal. In one implementation, the onboard energy storage device includes a capacitor such as a thin-film capacitor that stores sufficient energy to power onboard electronics without the need for an onboard battery. The card may be incorporated within various conventional apparatus such as a see-through and/or protective substrate, an item of clothing, an item of jewelry, a cell phone, a Personal Digital Assistant (PDA), a credit card, an identification card, a money holder, a wallet, a personal organizer, a keychain payment tag, and like personality.

A two part dual layer transaction device comprising a computerized master unit powered by rechargeable battery, the master unit capable of connecting wirelessly to a data network and accessing at least one network server, the master unit having a length, a width, and an internal volume, and a transaction card element having a form factor acceptable for use as a debit or credit card, wherein the transaction card element may be docked or otherwise coupled to the master unit in an idle state and may be uncoupled by the user for the purpose using or cleaning the card element.

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.

Aspects described herein may allow for a payment card assembly including a payment card having a first slot formed in a first surface therein, with the first slot having a bottom surface and pair of opposed side walls. A first cartridge houses electronic components and is removably received in the first slot. One or more first projections are formed on one of the first slot and the first cartridge. One or more first recesses are formed in the other of the first slot and the cartridge, with each first recess receiving a corresponding first projection to releasably retain the first cartridge in the first slot.
