I've been using currenc ever since it came out, over a year now, with very few problems. I find it much easier than dragging my wallet out for 3 pieces of info, and I can buy my lunch without needing to go to my locker.
It is a shame to see currenc having such set backs, I see people whining that samsung and apple pay are sooo much better.
News flash, samsung pay sucks, and so does apple pay. Why? Because they only work on samsung and apple phones! I guess at some point when samsung gets its head out of its ass and wants its app to be a standard it will open it up to all phones but until then, there is only one mobile wallet that works on my phone and with target. I know CurrenC support is effectively canceled in lieu of target pay, but I will be quite sad the day the app stops working.
Side note, as of the last version of the app, it has a small chance of shutting down the register when scanned. Did this twice, felt bad. 🙁
