First Claim
1. An electronic transaction card comprising:
- a Near-Field Communication (NFC) antenna;
an energy storage component; and
a processor configured to;
send and receive data packets to and from a terminal system to conduct a transaction using contactless payment technology, wherein the data packets include user authentication information to authenticate payment;
transmit, via the NFC antenna, an advertising packet from the electronic transaction card to a mobile power receiving device;
receive, via the NFC antenna, a response to the advertising packet from the mobile power receiving device, wherein the response indicates a first frequency of energy transmission via the NFC antenna;
alter the first frequency of energy transmission via the NFC antenna to a second frequency of energy transmission via the NFC antenna based on a distance between the electronic transaction card and the mobile power receiving device; and
broadcast, via the NFC antenna, a signal to the mobile power receiving device using the second frequency and configured to charge the mobile power receiving device via inductive charging.

Abstract
Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wirelessly charged by the first device via inductive charging.
