Yes. The software must have built in QR code functionality to present a QR code on the front of the plastic card. Although, a gift style card with just a wallet address is possible ofc.

These are effectively much more durable versions of 'paper wallets'. Production is actually quite time consuming, as the keys must be securely generated and printed in an always 'offline' environment on an individual basis. We are working to provide additional authenticity and certification measures for added security and transparency in this regard.

We would look to create a new crowdfunding pitch for this in the future perhaps.
