I just ran across The Top Ten Stories You Missed in 2006 in Foreign Policy. The tenth topic is quite interesting to me. After the launch of US epassports, a German hacker quickly found a vulnerability that allowing him to be able to clone the passport information. The report also says that besides American passports, those of citizens in 27 countries (mostly in Europe) that participate in the U.S. Visa Waiver Program are also at risk.
What about Thai epassport? Is it safe? Anyway, mine is still the paper version.
