How to add a Tangem card to XUMM & use a Tangem card to sign a transaction

To add a Tangem card to XUMM, open the account switcher ("Switch account") (upper right corner) and tap the Add account button.

Use the button Add Tangem card and hold your Tangem card against your phone if asked. The NFC reader is usually located on the top front / back of your phone. If your phone doesn't recognize your card:

1. Check (website of your phone vendor) where your NFC reader is located
2. Check if your phone features NFC support
3. Check if your OS (eg. iOS 13+) supports NFC cards

After adding your card, assuming your account is activated, sending and signing a transaction is easy: just follow the usual steps, and when asked, hold your Tangem card against your phone to sign.
