I've found that the auto-transit feature doesn't seem to work at readers that are looking for a 交通 FeLiCa chip -- this probably affects very few people here, but some KONAMI arcade machines don't seem to respond.
How long are you waiting before it responds? Is it instantaneous?
e-AMUSEMENT? (Which game(s)?) If auto-transit doesn't work, do you get a consistent ID if you fingerprint in for Suica? Thought I saw twitter videos showing this.
