Hi,
I'm Mirko, a Senior Android developer from Serbia,
I can developer this kind of application quickly. App will be developed, tested, and returned to you in 3 days (you will get complete source code, properly documented).
I also have one question, regarding exporting scan history to a server: can you provide me more details about this. (export as a one time action(example: user clicked on a button), or maybe when app is started, closed etc, or the service variant (with a timer and background sync)... It would be great if you can provide me more info about this.
Thanks in advance,
all the best.
