Kardhaus

Make a digital business card on iPhone

Digital business cards come in two kinds. One is an NFC card or a link that opens a page about you; the other is a contact that lands in the other person’s address book. Kardhaus makes the second kind, starting from the paper card you already have.

The Kardhaus Home Screen widget showing your own business card, with a finger tapping the Hand it over button. Two iPhones held together. The card leaves the upper phone by AirDrop and arrives on the lower one, which shows a delivered tick.

Making one

  1. Photograph your own card

    In My Card, choose Photograph the card in your hand. Name, title, company, phone and email are read into their fields, and the photo is what you hand over. No paper card? Pick one from Photos, choose yourself in Contacts, say it, or type it.

  2. Put it on the Home Screen

    Add the My Card widget and your card is on the Home Screen, so handing it over does not start with finding the app.

  3. Tap Hand it over, or Show QR

    If they have an iPhone, Hand it over opens the share sheet with AirDrop in the first row. If not, tap Show QR and their phone’s camera saves it as a contact.

What they receive

A contact file (.vcf) that opens in their own Contacts: nothing to install, no sign-up, no link to open later. AirDrop is a direct transfer between the two devices and the QR code is drawn on your iPhone, so neither passes through us.

The right-hand column describes how this kind of service usually works; each one differs.

When the other kind fits better

  • You want cards already handed out to update themselves. A link-based card changes for everyone who has the link.
  • You want to know who looked at your card. Some link-based services count views; Kardhaus does not.
  • You like tapping a card on someone’s phone. That is what NFC cards do.

More than one card

One for the day job, one for the side project, one with your personal number. You name them, and the widget shows the one you set as default.

Is My Card free?
Yes, for everyone; it is not a paid feature. Kardhaus itself is a free download.
Do they need an iPhone?
No. AirDrop works between Apple devices; on other phones, the camera scans the code behind Show QR and saves the same contact.
I already have a digital card in another app. Do I start again?
No. In My Card, choose Import from another card and scan its QR code, or pick a vCard or CSV file. A QR code that holds a vCard or MECARD is read directly; if it only holds a web address, export a vCard from that service first.
Can I print it?
Export it as a vector PDF, which stays sharp in print, or as a PNG image.
