How to say "the password is on the room key card" in Chinese

The sentence structure is: 密码 (mìmǎ) "password" + 在 (zài) "is at" + 房卡 (fángkǎ) "room key card" + 上 (shàng) "on." It follows the pattern: subject + 在 + location + 上.

Say this to a guest or colleague when they need the Wi-Fi password or a door code. It's a practical, neutral statement. In a hotel context, it's common to point to the card as you say it. Avoid using it outside of situations where a physical card is involved.
