1. A method comprising:
receiving a first signal by a transaction card;
responsive to receiving the first signal, transmitting a data packet from the transaction card to a mobile device;
responsive to transmitting the data packet, receiving, via a Near-Field Communications (NFC) antenna of the transaction card, a response from the mobile device, the response including a first frequency for energy transmission and distance data indicating a distance between the transaction card and the mobile device;
determining, via a microprocessor of the transaction card, a second frequency for energy transmission based on the first frequency and the distance; and
broadcasting, via the NFC antenna, a second signal to the mobile device at the second frequency to charge the mobile device via inductive charging.
