I don't want to be a downer on this because it sounds like a cool system, but it might be worth checking whats in the receipt paper as a lot of it is pretty bad for you:

Yes, the main problem is the paper with bisphenol, which has been banned in Europe.

Even though bisphenol-A is banned in EU, I believe bisphenol-B is still allowed. I suspect - though I don't know how to research whether it's true or false - that everyone just switched to bisphenol-B, which is said to be either similarly, or more toxic than BPA... :(

Even assuming that "BPA-free" paper I'd buy is really so, and not just BPA-covered one imported from China and said/labeled to be "BPA-free" by someone somewhere in the pipeline...

Yes. A short video I watched mentioned that even touching these thermal papers with normal gloves is unsafe.

The receipts that a large majority of humanity has been handling on a daily basis for decades? Unsafe? In what way?
