Moving collected data from one device to another

We are looking for a way to move collected data from one android device to
another

The specific scenario we want to implement is a s follows..

(1) We want our data collectors to collect data throughout the day in the
form on their device and at the end of the day be able to move all the
collected data from their device to their Supervisor's device and then
delete it from theirs (the data collectors device).

(2) Then the supervisor would review the collected data on his / her device
and after completion of the review, he/she would then submit it to the
aggregator server

If anyone has ideas for doing this we would be very appreciative.

Thanks,

Abie
