You have chosen to sponsor your bid up to a maximum amount of .
Only if you have Created QR CODE Generation and Android App and with an option for in house QR CODE printing in the past then bid. I want to get this job completed in one week. I assume that any bidder who is interested in doing this job has already done this job and has a writeup of how this can be achieved in full details. If you don't describe how this can be achieved in full details I will think that you are doing this job for the first time and wont answer to your bid.
Hope that clears everything.
