E-Passport security feature??

I recently read an interesting article on RFID US passports and that the US will require the 27 non-visa requiring countries to start issuing e-passports to it's citizens.

Here's the article:

There seem to be a security issue with the passport being read by someone other then customs officer. Even if the entire contents are encrypted (not currently planned), how long before the encryption method is broken.

Some RFID encryption systems have already been broken.. see http://rfidanalysis.org/

Anyone know how much data can fit on a RFID card?
