RE: carbon fibre protector Mark Langford, et al, posted to not have carbon fiber in the tail of the KR if you're going to run your antenna there, due to the interference with the radio transmition and receiving.
"the things you learn on the KRnet!" Would it work, if a small container was made from carbon fiber that enclosed your credit cards which have the card's information available to receptors at bank machines that will automatically read your card? My passport has this action as well and I would like to protect the info on my cards and passport using a small envelope of carbon fiber; perhaps with a thin layer of epoxy to keep the ends from fraying.
