Android App for Store Cards?

Picked up a few extra store cards that I don’t need to have hanging around my wallet, but are useful once a month or so.

Anyone have a recommendation for an Android App for storing that kind of card information and then using it for when it needs to be scanned at a checkout off the phone?

I use the Beep’nGo app which works at the Woolies and Coles scanners. Think it automatically downloaded onto my phone one day (Samsung bloatware) but I decided to try it and it’s going ok.

My wife has a different app which knows the Aussie cards and can show you their current discounts and catalogs. Can’t remember which one though.
