Whose memory is the business card?

In much of the world, the person enters the database through scraping, inference, or professional visibility. In Japan, the person may enter through the business card.

世界の多くでは、人間はスクレイピング、推論、職業上の可視性を通じてデータベースに入る。日本では、名刺を通じて入ることがある。

The card is small. It is polite. It is exchanged in a moment that still resembles encounter. That is why the Japanese case matters: the starting object is not anonymous data, but a socially accepted token of professional presence.

Then the card is scanned. Normalized. Linked to a company. Placed inside a relationship graph. Shared across a team. The exchange was between two people. The memory becomes organizational.

交換は二人のあいだで起きた。記憶は組織のものになる。

Sansan and Eight Team do not only store contact information. They convert a social object into shared infrastructure. The friction appears when personal exchange becomes team knowledge, and when relationship history becomes something the organization can activate.

The question is not whether business card management is useful. It often is. The question is who owns the relationship once the card has been absorbed into the system — and whether the person who exchanged it understood that absorption as part of the exchange.

問いは、名刺管理が有用かどうかではない。問いは、名刺がシステムに吸収されたあと、関係性は誰のものになるのか。そして、交換した本人は、その吸収を交換の一部として理解していたのか、ということである。
