APPARATUS, SYSTEM AND METHOD FOR COMMUNICATING DATA

An apparatus () configured to be connectable to a first electronic device () and a second electronic device (). The apparatus comprises: a memory (); a rechargeable battery (); a real time clock (); and engagement means. The engagement means is configured to releasably hold the apparatus in engagement with the first electronic device () to establish a first physical communication link between the apparatus () and the first electronic device (). The engagement means is configured to releasably hold the apparatus in engagement with the second electronic device () to establish a second physical communication link between the apparatus () and the second electronic device (). When held in engagement with the second electronic device () the apparatus () is configured to receive current time data from the second electronic device via the second physical communication link for storage in the real time clock (), and recharge the rechargeable battery by the second electronic device (). When subsequently held in engagement with the first electronic device () the apparatus () is configured to transmit current time data to the first electronic device () via the first physical communication link, receive data collected by the first electronic device () via the first physical communication link for storage in the memory (), and power the first electronic device with the rechargeable battery ().
