Offline data transfer between devices using gestures
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.
1. A method for operating a first data card, comprising:
receiving a first signal from at least one sensor of a first set of sensors provided at the first data card;
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;
interpreting the relative movement of the first data card in the first direction as a card pairing gesture;
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 between the first data card and the second data card over the peer-to-peer connection.
2. The method of claim 1 , further comprising:
detecting a geographical location of the first data card using a geo-location device provided at the first data card;
transmitting the geographical location of the first data card to a first server;
receiving a portion of a data file from the first server; and
locally storing the received portion of the data file at the first data card,
wherein exchanging the data with the second data card comprises transmitting the portion of the data file to the second data card.
3. The method of claim 1 , further comprising:
detecting that the first data card is connected to a data network via a first Subscriber Identity Module (SIM) provided at the first data card; and
synchronize data locally stored at the first data card with an offline data file stored at a first server over the data network.
4. The method of claim 1 , further comprising:
triggering a first haptic response using a haptic device provided at the first data card, in response to successfully establishing the peer-to-peer connection with the second data card; and
triggering a second haptic response using the haptic device in response to successfully exchanging the data with the second data card.
5. The method of claim 1 , wherein the peer-to-peer connection comprises a Near-Field Communication (NFC) protocol.
