What's the typical use case for a Xumm Tangem card?
Your Xumm Tangem card has its own r-address. It's a separate XRP Ledger account. Xumm, in combination with your Xumm Tangem card, enables all XRPL features.The most common use case would be to use two XRP Ledger accounts: one for receiving funds & daily spending and one for your savings. Your daily spending account in Xumm (as read/write account), and your savings account using a Xumm Tangem card.When you want to top up your spending account, you use your Xumm Tangem card to sign a transaction from your savings account to your spending account.When your spending account has a higher balance than you're comfortable with, you simply use Xumm to send some of your funds to your Xumm Tangem card account.
No, you cannot. While all Tangem cards feature a bank grade secure chip, the chip is programmed to work only for crypto-currencies with Apps supporting the cards. ATM's and retail payment terminals will not recognize a Xumm Tangem card.

Can I extract or backup the secret / private key from my Xumm Tangem card?
No, you cannot. The secret / private key of a Xumm Tangem card is stored safely inside the chip in the card. The card can only sign for you, it will never expose the secret / private key.While you cannot extract & backup the secret / private key of the card, Xumm can setup a recovery account, and attach the recovery account to your Xumm Tangem card account. Using this recovery account, you will be able to regain access to your funds in case of a lost, stolen or damaged card.
How is the Xumm Tangem card protected? Can someone else use my card if they have physical access?
Xumm will allow you to setup a PIN / Password on your card. If you do so, signing transactions with your card also requires that you to enter the PIN / Password. This will protect you against physical access attacks, as one not only needs your card, but your PIN / Password as well.
If you did not configure a PIN / Password on your card, anyone with physical access to the card can move all your funds.
If you use your Xumm Tangem card to keep significant amounts of XRP (or other currencies), it is advisable to both enable PIN / Password protection on your card and not to keep your card with you during your daily commute.
Where will Xumm Tangem Cards be shipped?
To most countries around the world.
