Download the Ballet app to use the card. Open the app ecan the QR code on the front to add the wallet. You can deposit coins directly to the QR code on the front.
When you are ready to send the BTC, peel off the top QR code to reveal a send QR code. It will then request a passphrase. Scratch off and enter the passphrase. Now you can send.
Some people feel the wallet is not safe. I watched the manufacturing process and the two pieces needed to send BTC are manufactured at seperate locations according to the company. This is a good starter wallet for self custody, but it is questionable for holding large amounts of BTC due to the possibility of the company keeping record of the seed phrase.
