Very good. I made some tests, back when I was at the university. We had a Hardware Lab with Radio-Test Equipment and RFID Readers/Writers.
I have this one:

It just works. The Signal/Noise-Ratio and amplitude of the RFID-Signal (in the casing) is just too small, to trigger a rfid response.
- pbhjpbhj 11y agoWhat material is actually used in your linked shield for "Schnüffel-Chips" [fantastic word!] ? Is it just foil lined or is there a mesh, what material is the mesh and what pitch? I'd imagine you could have an active mask too [eg just a RFID with false data] that would return some signal just not the one being sought.
- maze-le 11y agoI don't know what material it is exactly but it is a mesh, and suprisingly thin and flexible. Your idea of an active fake-chip is really nice, it could actually work (on non-encrypted content).
