I have continued to test patterns for making wallets. The construction also improves with each revision. You can see from left to right versions one to four. I switched from vertical to horizontal pockets, because it was pointed out to me that cards may fall out.
I continue to work on my pattern making skills by laser cutting pattern pieces. The TitanRF shielding also is being tested as I continue to see walk by exploits on tap to pay in the wild.
plywood patterns for testing.
