DETAILED DESCRIPTION
• The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
• Individuals often carry transaction cards to enable the individuals to conduct transactions using the transaction cards, e.g., by using the transaction cards to purchase goods or services at retail stores, from online shopping websites, from other individuals, or the like. While transaction cards may be useful when being used to conduct transactions, transaction cards may not have any other use outside of the transaction context. Accordingly, individuals often carry transaction cards for extended periods of time while only making use of the transaction cards when conducting a transaction.
• Some implementations, described herein, provide a transaction card for transferring solar power to one or more other devices. For example, a transaction card may include a solar layer for generating electricity from sunlight using solar cells. The transaction card may also include a power transfer layer for obtaining the electricity from the solar layer and allowing the electricity to be transferred to an electronic device (e.g., wirelessly via inductive charging and/or using physical contacts). The transaction card may also include a transaction card layer that is capable of providing support for the other layers and/or providing transaction data to a transaction terminal (e.g., to enable the transaction card to be used for making purchases of goods or services).
• By including a solar layer and power transfer layer in a transaction card, the transaction card may be capable of charging electronic devices, e.g., when not in use for conducting a transaction. The ability to use a transaction card to charge an electronic device may obviate the need for an individual to carry other devices for charging the electronic device. The use of solar power creates a readily accessible and renewable source of power. In some implementations, the power transfer layer may include components to enable wireless charging of devices capable of wireless charging, such as cellular phones. In some implementations, the power transfer layer may include a battery to enable storage of electricity to be used for charging at a later time. The transaction card may also be used as a transaction card (e.g., capable of being used for purchasing goods and services), providing an individual with a useful multi-purpose device in a form factor that is easily portable.
• FIGS. 1A-1B are diagrams ofoverviews100 and150 of an example implementation of a transaction card described herein. As shown inFIG. 1A, theoverview100 of the example implementation may include asolar layer110, atransaction card layer120, and apower transfer layer130. The three example layers are also depicted as combined into anexample transaction card140.
• As shown inFIG. 1A, theexample transaction card140 includes asolar layer110. Thesolar layer110 includes one or more components designed to generate and supply solar electricity. For example, the solar layer may include one or more solar panels. A solar panel may include a variety of components, such as a cover (e.g., constructed from transparent or semi-transparent glass, plexiglass, polycarbonate, or the like), one or more encapsulant layers (e.g., constructed from ethylene vinyl acetate (EVA), clear silicone, or the like), one or more solar cells (e.g., a photovoltaic cell that may be constructed from a variety of materials, including crystalline silicon, amorphous silicon (a-Si), cadmium telluride (CdTe), or the like), and a backsheet (e.g., constructed from polyvinyl fluoride (PVF), polyethylene terephthalate (PET), or the like). In some implementations, thesolar layer110 may include other components, whether the other components relate to the generation of electricity from light or whether the components relate to other functionality, such as transferring or storing electricity.
• As further shown inFIG. 1A, theexample transaction card140 includes atransaction card layer120. Thetransaction card layer120 includes one or more components designed to enable the transaction card to be used to conduct a transaction (e.g., to purchase goods and services). For example, thetransaction card layer120 may include a magnetic strip, integrated circuit chip, RF antenna, and/or RFID tag to provide information associated with the transaction card140 (e.g., an account identifier, account information, a payment token, or the like). In some implementations, thetransaction card layer120 may include other components, such as components designed to physically support components of one or more other layers, such assolar layer110 andpower transfer layer130.
• As further shown inFIG. 1A, theexample transaction card140 includes apower transfer layer130. Thepower transfer layer130 includes one or more components designed to receive electricity from thesolar layer110 and provide electricity as output. For example, thepower transfer layer130 may include a battery (e.g., a thin or ultra-thin lithium polymer rechargeable battery, a thin-film lithium-ion battery, or the like), one or more electrical contacts (e.g., electrically conductive material capable of transferring electricity through contact, such as copper, gold, silver, or the like), a wireless power transfer component (e.g., an inductive coil or antenna, such as a near-field communications (NFC) antenna, capable of generating an alternating electromagnetic field for creating inductive coupling with an electronic device to form an air transformer), and/or circuitry on a printed circuit board (PCB) including various components for managing the transfer of electricity from thesolar layer110 to an electronic device (e.g., via the one or more electrical contacts or the wireless power transfer component). In some implementations, thepower transfer layer130 may include other components, whether the other components relate to the transfer of electricity or whether the components relate to other functionality.
• As further shown inFIG. 1A,transaction card140 may include other components, such as a logo identifying an organization associated with thetransaction card140, lettering identifying a user associated with thetransaction card140, numbers indicating an account number and expiration date, a signature strip for a signature of the user associated with thetransaction card140, or the like.
• While example components inoverview100 ofFIG. 1A are depicted and described as being included in three separate layers (e.g.,solar layer110,transaction card layer120, and power transfer layer130), the distinction between layers may, in some implementations, be logical, rather than actual dedicated layers for each of the functions described above. For example, various components described with respect to thesolar layer110 may be included in, or include, components described as being included in thetransaction card layer120 and/orpower transfer layer130. Similarly, various components described with respect to thetransaction card layer120 may be included in, or include, components described as being included in thesolar layer110 and/orpower transfer layer130. Likewise, various components described with respect to thepower transfer layer130 may be included in, or include, components described as being included in thesolar layer110 and/ortransaction card layer120. In addition, the sizes of the layers, while depicted as each being the same size, may vary. By way of example, theexample transaction card140 includes a smallersolar layer110 embedded in atransaction card layer120 that is larger than thesolar layer110. Other configurations and layouts are also possible.
• As shown inFIG. 1B, theoverview150 of the example implementation depicts thetransaction card140 and an electronic device155 (e.g., the device to receive power fromtransaction card140, such as a cell phone, tablet computer, laptop computer, video game device, battery pack, wearable device, or any other type of device capable of receiving an electrical charge). As shown inFIG. 1B, and byreference number160, thetransaction card140 receives sunlight by having the solar panels included in thetransaction card140 exposed to the sun. The solar panels included in thesolar layer110 of thetransaction card140 convert the sunlight into electricity, which can be stored by components included in thesolar layer110 and/or thepower transfer layer130 of thetransaction card140. While the example depicted inFIG. 1B includes the sun as the source of light, in some situations, other light sources may also enable solar panels to convert light into electricity (e.g., incandescent light bulbs, fluorescent light bulbs, or the like).
• As further shown inFIG. 1B, and byreference number170, thetransaction card140 is placed on or near theelectronic device155. By placing thetransaction card140 on or near theelectronic device155, power may be transferred from thepower transfer layer130 of thetransaction card140 to theelectronic device155. For example, in a situation where thepower transfer layer130 and theelectronic device155 include inductive charging components, placing thetransaction card140 on or near theelectronic device155 may create an inductive coupling, causing power to be transferred from the inductive components included in thetransaction card140 to the inductive components included in theelectronic device155. As another example,transaction card140 may include electrical contacts (e.g., metal contacts included in thepower transfer layer130 of the transaction card140) that make contact with corresponding electrical contacts of theelectronic device155 to enable the transfer of power from thetransaction card140 to theelectronic device155. While the example depicted inFIG. 1B shows theelectronic device155 in contact or proximity to thetransaction card140 to receive power, in some implementations, an intermediate component may be used to transfer power from thetransaction card140 to theelectronic device155, such as a cable connected to theelectronic device155, a case with contacts and/or inductive components connected to theelectronic device155, or the like.
• Accordingly, by including asolar layer110 andpower transfer layer130 in atransaction card140, thetransaction card140 may be capable of charging electronic devices, e.g., when not in use for conducting a transaction. As noted above, the ability to use atransaction card140 to charge an electronic device may obviate the need for an individual to carry another device for charging the electronic device. The use of solar power creates a readily accessible and renewable source of power. Thetransaction card140 may also be used to conduct transactions (e.g., capable of being used for purchasing goods and services), providing an individual with a useful multi-purpose device in a form factor that is easily portable.
• As indicated above,FIGS. 1A-1B are provided merely as examples. Other examples are possible and may differ from what was described with regard toFIGS. 1A-1B.

Example input devices oftransaction terminal220 may include a number keypad, a touchscreen, a magnetic strip reader, a chip reader, and/or an RF signal reader. A magnetic strip reader oftransaction terminal220 may receive transaction card data as a magnetic strip oftransaction card210 is swiped along the magnetic strip reader. A chip reader oftransaction terminal220 may receive transaction card data from an IC chip (e.g., an EMV chip) oftransaction card210 when the chip is placed in contact with the chip reader. An RF signal reader oftransaction terminal220 may enable contactless transactions fromtransaction card210 by obtaining transaction card data wirelessly fromtransaction card210 astransaction card210 comes within a range oftransaction terminal220 that the RF signal reader may detect an RF signal from an RF antenna oftransaction card210.

• Transaction backend240 includes one or more devices capable of authorizing and/or facilitating a transaction. For example,transaction backend240 may include one or more servers and/or computers to store and/or provide information (e.g., authorizations, balances, payment tokens, security information, account information, or the like) associated with processing a transaction viatransaction terminal220.
• Transaction backend240 may include one or more devices associated with banks and/or transaction card associations that authorize the transaction and/or facilitate a transfer of funds or payments between an account of a cardholder oftransaction card210 and an account of an individual or business oftransaction terminal220.
