Nintendo invited members of the Japanese press, Japanese game industry and Japanese financial industry to its Nintendo Conference. Approximately 1200 business cards were collected. They have gone missing.
Nintendo has confirmed that the business cards have gone AWOL and says the company is investigating the matter. Nintendo is hoping that by making this known publicly, it will be able to rectify the situation and track down the missing business cards.
The company is taking steps so this does not happen again the future.
