Too many steps Most merchants will sit down with batches of items to scan. This app takes you to a history screen every time you scan something, which is an extra step to get back to scanning. Then when you scan, you have to tap the redeem button, then tap ANOTHER redeem button. This is making what should be a simple scan-redeem-scan-redeem action much more of a hassle than necessary.
You should be able to scan without having to login, but NO! you have to login again....and again...and... OMG
app is usefull
