This little gem never left my wallet since last time; it’s my very own e-Amusement pass.
The card keeps track of your progress of various (Konami) games in the arcade halls.

Recently I’ve found out that after 100 days of non usage the card resets itself, unless you register it on the all Japanese Konami website….
Luckily I Google-translated the hell out of that website during my last holiday in Japan, unaware of the fact that it would lift the expiry thing 😉
