Pass is the same word in English and German. It can mean the document that lets a traveller cross borders, the card or ticket that opens doors, as in a museum pass or rail pass, and, in Swiss geography, the high road over a mountain range. Each reading points to movement and access. With bitcoin in front, the name describes a way to travel, enter or belong. The .ch ending ties it to Switzerland, a country known for tourism, rail travel and its alpine crossings.
The name sits in the travel category without a bundle. The same name is held on .de and .org, and the set can be acquired together for a cross-border programme. Typical projects include a membership pass that grants benefits at Bitcoin-accepting hotels and restaurants, a travel agency for Bitcoin holders, a digital guest card for a Swiss region, or a self-guided route through alpine destinations.
