A contactless card with power harvesting unit is described. The power harvesting unit is configured to harvest power from near field communication radio wave fields and supply power to a memory, processor, and communication circuit of the contactless card. In some embodiments, the contactless card may also include a capacitor for smoothing out power deliver or a rechargeable battery. The contactless card is configured to establish two-way communication with a secondary device and to store and execute applets. In some embodiments, the contactless card is a payment card which contains information associated with a primary profile and a secondary profile. The secondary profile may be activated using two-way communication if the primary profile is deactivated due to fraudulent activity.

A charging locker includes a charging locker frame defining a locker stack compartment and an adjacent wiring and access compartment. A plurality of lockers are located within the locker stack compartment. A plurality of locker doors are provided which correspond to the plurality of lockers, and selectively individually provide access to interiors of respective lockers from a front of the charging locker. The charging locker also includes a wiring and access compartment door selectively providing access to an interior of the wiring and access compartment from the front of the charging locker. The wiring and access compartment is configured to extend in a vertical direction and is horizontally adjacent to each of the lockers located within the locker stack compartment.

A device charging station apparatus for offering convenient a charging solution and new revenue for businesses includes a housing and a plurality of cubby doors to selectively cover or expose a plurality of cubby apertures of the housing. A plurality of charging ports is coupled to the housing within the cubby apertures. A payment interface is coupled to the housing and includes a pay display, a keypad, and a card reader in operational communication with a CPU. A power source is coupled to the housing and is in operational communication with the electronic lock of each of the plurality of cubby doors, the plurality of charging ports, the CPU, and the payment interface.

A controller of a transaction card may cause the transaction card to be in a first state. The transaction card may include a battery and at least one other component. In the first state, the battery does not provide power to the at least one other component of the transaction card. The transaction card may receive a signal from a near-field communication (NFC) device and may cause the transaction card to be in a second state based on receiving the signal. In the second state, the battery provides power to the at least one other component of the transaction card. The transaction card may perform a transaction based on the transaction card being in the second state.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices. To charge, the machines employ electrical current from an external source. As demand at individual collection, charging and distribution machines increases or decreases relative to other collection, charging and distribution machines, a distribution management system initiates redistribution of portable electrical energy storage devices from one collection, charging and distribution machine to another collection, charging and distribution machine in an expeditious manner. Also, redeemable incentives are offered to users to return or exchange their portable electrical energy storage devices at selected collection, charging and distribution machines within the network to effect the redistribution.

Provided is a device for transmitting wireless power. The wireless power transmitting device includes a communication unit, a power receiving unit, and a processor. The processor is configured to obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device, establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information, and control to transmit the location information to the wireless power transmitting device. The power receiving unit wirelessly receives the power from the wireless power transmitting device after the communication unit transmits the location information.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. By default, each portable electrical energy storage device is disabled from accepting a charge unless it receives authentication information from an authorized collection, charging and distribution machine, other authorized charging device, or other authorized device that transmits the authentication credentials. Also, by default, each portable electrical energy storage device is disabled from releasing energy unless it receives authentication information from an external device to which it will provide power, such as a vehicle or other authorization device.
