Korean company MobiBlu has launched a new version of its DAH-1800T mp3 player with the RFID smart card on board, used on the Korean public transportation system.

Usually, you’d have to take your card out and swipe it across the appropriate reader before boarding the train, but if everything goes according to plan with MobiBlu’s new unit, you can still blast the tunes while just rubbing your pocket against the reader and continue on your way.

This is certainly an interesting innovation on the Korean manufacturer’s part, now they just need to integrate a mobile phone, and some games on the thing and maybe it’ll fly state-side.
