Too many reward cards?

Just discovered a free app called Stocard which scans and saves your member cards for many different stores, hotels and airlines. Found it very easy to use and it even lets you save custom cards.

iOS - https://itunes.apple.com/ca/app/stocard-rewards-cards/id444578884

I think there's also a feature where it can detect your location and remind you to use your card if you're in an eligible retailer but I've turned that off.

I haven't used the app while shopping yet so no clue if stores accept Stocard.

Superstore should be okay since they have new scanners for their PC Plus program.
Shopper's Drug Mart is reportedly anal about not scanning smartphones and not manually entering in card numbers.

 

There is also Coin - be great if all banks issue their cards through Coin instead of physical cards and also Translink would use Coin for their Compass card.

I have been using an app called Cardstar for years.

 

@Night Of GuardianS do you find that retailers are able to scan the cards no problem?
