A vCard QR code lets someone save your contact from a scan. FutureQR has a free one you can make with no account, and a Pro digital business card you can change after it is printed.
On the home page, choose Contact. Add your name and at least a phone, an email or a website. The contact is stored in the QR code. It works with no internet, and it is never sent to FutureQR. Download PNG or SVG. If the phone number changes, make a new code and replace the printed one.
A Pro contact card is a short link, not the contact itself. People scan it, open a page, and tap Save contact. You can change the phone, email or title later. The printed code stays the same, and scans are counted. It uses one active code.
That is the card for a realtor, a sales team, a conference, or anyone who will hand the same card out for months. A contact card you can update is part of Pro. A free account still includes 2 dynamic codes with basic designs.
The Pro page also offers the same contact as a .vcf file, so a phone can add it from the short link.
