Languages, where the data sits, the address, the contact file, the price, the app: six checks for a digital business card in Switzerland, and where Vizy stands.

What a QR code on a business card actually does, the two ways to make one, and the mistakes that leave it unreadable, or dead after six months.

A limited trial, a tier with a logo, or actually free? The four models behind "free" digital business cards, and the questions to ask before handing out an address.

How an NFC card and a QR code work, what each asks of the phone across the table, what it costs, and why both should lead to the same page.

A coach sells a relationship, and it starts with "get back to me". What a digital business card must carry for a coach or a consultant, and where to put the QR code.

A viewing, a sign, a flyer in a letterbox. An agent is contacted by people in a hurry. What their digital card must hold, and where the QR code works for them.

Plumber, electrician, joiner, painter. People call you when something is broken, and look for you in a phone. What your card must hold, and where to stick the QR code.

Linktree gathers a creator's links for their audience; Vizy hands your details to a person you have just met. What each does well, and which fits your line of work.

The format behind the "Add to contacts" button. What a .vcf file holds, how iPhone and Android read it, and why a saved copy never updates itself.

The five things that matter, the ones you can drop, and the Swiss particulars: four languages, legal form, and an address that does not expire.
