How do you recharge it? Do you have to swap the battery?

love this. would be cool if we can see and perform all kinds of banking txns on this. Think ledger but all in one card. Super cool. Even cooler would be card to card money transfer without use of swipe machines

I want this, but only for one thing: email.
I already use an pwnagotchi, and it works great for this - but its a bit bulky.
If I can get this set up and working, it'll be my main interface to email.

This post - the title made me remember ... ( as a credit card is about the same size as a business card )
A Linux Business Card CD is a miniature, credit-card-sized optical disc containing a stripped-down, bootable Linux operating system. They hold around 50MB to 100MB of data and were highly popular in the early-to-mid 2000s
I would love if the screen could take up more space, even at the expense of a little extra thickness.

I think that there could be a wider screen if such formats are available. Once we have betavoltaic batteries, the entire card can be screen.

I'm not sure beta voltaics will ever reach LiPo densities. All materials I know would be unwise to place in your wallet, or anywhere near your body.
If we are OK with a battery and a beta voltaic source, a tritium one is reasonably safe and can trickle charge the battery when the device is in deep low power mode. The battery can still be charged by the induction coil.

Can it run DOOM?

It seems like it might be a little expensive for a business card...
