Someone scans the code, and the phone offers to save the contact. Make one contact card (vCard) or a list of them in one run. Free, no sign-up.
Typing a number from a paper card into a phone takes time, and a wrong digit means the number does not work. Put the code on the back of a business card, on a badge, on the last slide of a talk or on a stand at the counter.
An event team prints a badge for every attendee, and a sales department orders new cards when the phone numbers change. The page QR codes from Excel walks through the import.
For the guest network at the same event, use the page Wi-Fi QR codes to print a sign with the password.
The phone saves everything you entered for that person. The generator packs the data as vCard 3.0, a standard format that iPhone and Android read with the built-in camera.
No, the contact sits in the code itself and not behind a link to an outside service, so the phone reads it offline.
No. The code keeps what you entered when you made it. If the phone number changes, make a new code and print it again.
Prepare a CSV or Excel (XLSX) file with the name in the first column and the phone in the second. Import it on this page. One run takes up to 1,500 contacts, and rows with errors go into a report with row numbers. For a caption under the code, add a column and assign it to "Caption" after the file loads.
People scan a business card from 10–15 cm (3.9–5.9 in). A contact card with an email and an organization holds more data than a plain link, so its code is denser than a link code. Print it at 2 cm (0.8 in) or more. The form has a 3 cm (1.2 in) preset for business cards and badges.
Every contact in the list has a × field. Enter how many times to print that contact. With 40 in the field, one contact fills a whole A4 sheet of 2 cm codes.
