It is not different than with any other chip card.  If you immerse the
card into water only the contacts my corrode.  Use an eraser to clean
them.  If you bend the card to strong the chip may get an microfissure
and stop working.

I have several chip cards in my purse for may years now without any
problems.  Granted most money cards still use the magstripe but at least
my OpenPGP card and my RFID based season ticket are chip-only cards.

As an alternative you may use an ID-000 (GSM card size) card along with
an USB reader and put it on your key ring.  I had one on mine for at
least 4 years and it surived summer, winter, snow and sun without any
problems.


Salam-Shalom,

Re: Smartcard durability?

2011-07-28 Thread David Tomaschik
It's a small sample to be sure, but I've been carrying my smartcard in
my wallet for several months and it's held up just fine.  It has a
tiny bit of curvature to it now, but that's only noticeable if you lay
it on something flat, and has no impact on its usage.  (If it matters
any, I carry my wallet in a front pocket -- I know some people sit on
theirs which might be a bit worse for it.)
