I am a little surprised that I am not (yet?) a member in any frequent flyer program, even more so as my wallet presently contains

• a video store membership card,
• a prepaid metro pass,
• a Chinese international telephone card,
• several Japanese and Korean telephone cards,
• an electronics store point card,
• a hospital patient identification card,
• a chain drug store point card,
• a public library membership card,
• two Japanese bank's cash cards,
• a credit card,
• a commuter pass,
• stamp-collecting albums from two bakeries, Starbucks Korea, Virgin megastore, Seattle's Best and a hotel
• two Internet cafe membership cards,
• membership cards from a gym and a swimming pool,
• a Youth Hostel membership card,
• and a supermarket point card.

I am also planning to participate in the Astro Boy Stamp Rally.
