How do I add a card?
Tap + at the bottom, pick the shop (or “Custom card”) and scan the code on your card. You can also use a photo or type in the number.
Why didn't my card open by itself in the shop?
Check that Cardo is allowed to use your location and that “Open card by location” is turned on in the app's Settings. When you are standing between several shops, Cardo offers their cards at the bottom of the main screen. In places where you use a card repeatedly, it learns.
The checkout can't read the code
When a card is shown, the screen brightness goes up to maximum automatically. If that doesn't help, read out the number printed under the code.
How do I move my cards to a new phone?
Just sign in to your account on the new phone — your cards download by themselves. Cardo also makes a daily backup on the phone, and you can export your cards to a file in Settings.
I forgot my password
On the sign-in screen choose “Sign in”, enter your e-mail and tap “Forgot password?”. You will get a link to set a new password.
How do I delete my account and data?
In the app: Settings → Delete account. This deletes the account and all cards. More options on the Account deletion page.
