IC cards can be read from a distance as well. I can use my building security card when it is in my wallet and the wallet is inside my briefcase. Reading the data off of cards on a crowded train would not be difficult.
Breaking the encryption is another matter though, hence my comment above. With current technology the strongest encryption systems are not breakable (as long as the key is good enough). However a sudden jump in computing power or a newly found weakness in the encryption system would quickly change the rules.
