Comments on Coin for Android

★★★★★ NFC saves the day I have been able to skip the chip with NFC. It works beautifully when it works.

★★★★★ Great product Would be 5 stars but the not working on all readers .have not been able to try to see if nfc works due to lack of cards compatible.

★★★★★ Great card and companion app The coin card and app work great. I have found coin is accepted most places I go so there are no issues. It's great to only have to carry one card around. The app is fairly easy to use but it is easier to input the card manually than have it read with the included dongle. Highly recommend!

★★☆☆☆ Samsung myKNOX container support missing The app doesn't sync with my coin card when in the Samsung myKNOX container making the card useless to me.

★★☆☆☆ Doesn't work on Nougat Force closes when you try to sync. I know the company isn't around anymore, but come on. Yeesh.

★★☆☆☆ The app and card are both lousy. The app erased my cards after several days of use. When the app was working during those several days, the card only worked on about half of the transactions I tried to make. Loading and syncing the cards into the app was a frustrating enough endeavor to take on once - the swiping mechanism reads when it feels like it - why should I want to try reloading the cards if they are going disappear? Overall this card and app prove more hassle and inconvenience than just not having them. I feel ripped off.

Trust & Safety: The app requests location, camera, microphone, NFC, storage, and network permissions, plus Bluetooth access to enable card syncing. This is typical for hardware wallet integrations but warrants user awareness of data handling. Development notes show Crashlytics/Fabric usage and not_proguarded status, which has implications for stability and code exposure.
