    I've used the foil blocking sleeves for ages, partially to avoid someone trying to hax0r but mainly to stop cards interfering. So far they’ve done the job and they can get a bit tatty after a year or 2 of constant in/out use but, at about a buck each who cares :)

    Did much thinner layer of foil and just slipped it in behind my credit card. Both the credit card and foil fit in the same pocket without any problems so I'll just leave it like that.

    I did think of melting the Go Card down like someone suggested and putting the chip into my phone case but didn't want to loose my Go Card deposit.

    Since when was there a deposit for a go card? :S Mine was $30 with $30 credit. And at what point would you ever return it?

    As to my typical solution to this thread. My leather wallet folds open (obv), but then folds out again for the clear section with license. Just have Go Card behind the license so I can flick it open. I have found those that even closed provided I tap the correct side it works fine.

    I know you found a solution with the foil - but just as a matter of interest, maybe for others - you can get "blocking sleeves" for cards. Something like this might work:

    http://www.minitravelmates.com.au/rfid-blocking-passport-sleeve/
    http://idcardworld.com.au/RFID_Blocking.html
    http://www.identitech.com.au/our-pr...lastic-card-accessoriesrfid-shielded-sleeves/

    You can get all sorts from eBay as well.

    Not sure how well they work, but might be useful.

    Cheers
    Mike

    There's a solvent you can use, metho or something like that. Acetone?
