Is there is a card "wallet" app that doesn't require the net?

[Andy Burnelli]

Does anyone know if there is a "wallet" app that doesn't require the net?

Based on another thread, I tested a "Cards" app that Andy Burns uses.
*Cards* - Mobile Wallet, by Cards
free, ad free, requires GSF, Rated 4.4, 5M+ Installs
<https://play.google.com/store/apps/details?id=com.cardsapp.android>

It's a nice app that allows all sorts of cards to be added to a wallet.

It even allows you to make a card without needing to sign into the net.

But if you accidentally "sign out" as "Guest", you lose everything.

Given the whole point is to save your cards in an encrypted wallet that is
_not_ on the Internet (what good is that?), do you know of an encrypted card
wallet app that keeps all your private data completely on your phone?
