Summary

This covers the basic components of the wallet, which helps understanding how it operates. The core electronics are located under a soldered RF shield and not yet visible, opening this up may follow at a later time. Notably, the wallet is still operational after the steps shown here, so it appears that there are no tamper detection sensors in this part of the hardware.
