Abstract: A method for operating a first data card includes receiving a first signal from at least one sensor of a first set of sensors provided at the first data card. The method continues by detecting, based on the first signal, a movement of the first data card relative to a second data card in a first direction within a pre-selected distance from the second data card, and interpreting the relative movement of the first data card in the first direction as a card pairing gesture. The method continues by establishing a peer-to-peer connection between the first data card and the second data card, in response to the card pairing gesture, and exchanging the data with the second data card over the peer-to-peer connection.

Abstract: A system is provided including a first server storing a first data file for a first user, a second server storing a second data file for a second user, a first data card of the first user registered with the first server and locally storing a portion of the first data file, and a second data card of the second user registered with the second server and associated with the second data file. The first data card detects a pairing gesture between the first and second data cards, and in response, establishes a peer-to-peer connection between the data cards.

The first data card detects a pairing gesture between the first and second data cards, and in response, establishes a peer-to-peer connection between the data cards. The first data card subsequently detects a transfer gesture between the first and second data cards, and in response, transmits the portion of the first data file from the first data card to the second data card over the peer-to-peer connection.
