Digital business card vs QR code.
A QR code is a way in: a printed or on-screen pattern a camera turns into text, usually a web address. A digital business card is what opens: a page with your details, links and a Save button. Most digital cards are shared by QR code, and a QR code can also hold a contact directly.

Three things “QR business card” can mean.
People ask “QR code or digital card?” when they mean one of these. Only the first is a QR code standing alone.
| Kind | What scanning does | After your details change |
|---|---|---|
| A vCard QR code on paper | Offers to save the contact, even offline | Wrong until reprinted |
| A link QR code on paper | Opens your digital card | Right: you edit the card |
| A QR code on your phone or Wallet pass | Opens your digital card | Right, and the pass can update too |

The QR is part of the card.
On a Wallet pass the two stop being alternatives: the code is how the card is shared, and the pass is how you carry it.

A QR code alone is enough when.
Pick by where the code lives and how long it lives there.
- A badge or a one-day event, with poor signal A vCard QR code It saves the contact with no connection, and a one-day badge will not outlive your details.
- Cards you will hand out for a year or more A QR code to a digital card The printed code never changes while the card behind it does.
- Meeting people with your phone in your hand A digital card on a Wallet pass The code is in Wallet, a double-click of the side button away when that Wallet setting is on, opens with no signal on your side, and updates when you edit the card.

Common questions.
Is a QR code a digital business card?
A QR code that holds a vCard works as a very simple one: scanning it saves the contact. Most digital business cards are web pages, and the QR code is how they are opened.
Do I need a digital business card if I have a QR code?
Not if a fixed contact is enough. A card earns its place when your details change, when you want links and a photo, or when you want the other person to be able to send their details back.
Can a QR code business card work offline?
A vCard QR code saves the contact offline. A code that opens a page needs a connection on the scanner’s phone; a Wallet pass shows its code with no signal on yours.
Which QR code is best for a business card?
A short link to a card you can edit: it makes a coarse code that scans in dim light and stays right after you print it.
A QR code with a card behind it.
Your Cardr card comes with a permanent QR code to your own address, on your phone and ready to print. Free forever.
