Made a new wallet for myself, out of duct tape and copper mesh.

It's not paranoia if you've just watched Citizenfour.

You wrapped the copper mesh with the duct tape? (if so, I've got what I want for my birthday from my $relative who makes duct tape wallets). And I'm assuming that a closed wallet then becomes a Faraday cage?

Yes, copper mesh wrapped in duct tape so that it forms a Faraday cage, more or less. Obviously  it's not perfect, but it stops my phone's NFC reader from reading my travel card, at least.

@liw@identi.ca no such thing as too paranoid anymore. We know various 'they's are indeed out to get us (or at least all our data). Good for you I say. More people should be so awake.
