A quick search didn't reveal this has been posted so I thought I would do it.
I have the Pen Fed Visa Platinum cash Rewards card often talked about on this site. Pen Fed are now offering to convert their Visa cards to the style containing a 'chip' which will facilitate easier use internationally. This credit card has no foreign transaction fees which are now common with other US credit cards. This change will make using this card a breeze overseas.
See the Pen Fed site for details.
