The card itself is just a piece of plastic, it is the microchip that is the important part and I am not aware of any 3D printing system that could print something that complex just yet.
- derefr 13y agoHow many gates does a chip need if it's basically a single-purpose crypto ASIC? Presuming you can expand the traces out to cover the entire back of the card (no die, just raw PCB), what process size would you need? I guess, if that doesn't work, we could always just work on an Open Smartcard Microcontroller For FPGA-based Cards. Then the one thing you need to trust is that FPGAs don't have a special backdoor mode for when they somehow detect that the chip they're running is doing crypto ;)
