Populate information to another form

Is there a way to transfer information from one form to another? We are
working on a huge forms(with many variables). We are concerned about the
performance and feel more comfortable to divide it into two. We are
thinking about using an id to link them but feel there would be no control
for the user to enter the ids consistently. I would appreciate any
suggestion to link two forms. w

Barcodes are useful for relating two different forms. Your data collectors
would carry a set of barcode stickers and blank interview (index) cards,
and transfer one to a blank interview card at the start of the interview
sequence, and scan that card at the start of each interview.

The barcodes for the different forms would then be correlated during your
data analysis.

The interview cards may also be useful for motivating data collectors, as
they can see an ever-growing stack of their own completed interviews as
they head out and return from your offices each day.

Thank you Mitch for the barcode suggestion. I just got chance to try and
it works very well. May I ask the battery usage for the scanner on tablet?
We experience battery shortage during the survey and wondering if the
scanner would take more power.
Thanks,
Wen

The main battery draws are:

(1) display screen
(2) wifi / cellular radio
(3) GPS

If you are working outside of cell / wi-fi range, place the device in
Airport Mode. This ensures that the radios are off. When the tower signals
are weak, the device will expend more and more energy trying to communicate
with them. The very first Amazon tablets drained their batteries very
quickly when backpackers took them into the wilderness because they didn't
have an "Airport Mode" option.

If you need GPS, you may need to exit Airport Mode to capture GPS (not sure
this is necessary).
