QR codes on business cards
A business card gives a code about four square centimeters to work with. That is enough. Print it at 2cm or larger, leave four modules of white space around it, and it scans at arm's length on the first try. Make the code dynamic and a job change no longer wastes the box: you edit the destination once and every card you handed out points to your current details.

Sharp at 2cm
A 2 x 2cm code at 300dpi scans from a hand's length away. A dynamic code helps here: it encodes a short link, so the pattern stays coarse and easy to read at small sizes.
Quiet zone included
Scanners need clear space around the code to find its edges. Keep a margin of about four modules and keep your card's background pattern out of it.
Outlives your job title
New role, new number, same cards. Update the destination behind the code and the cards already in circulation stay correct.
Common questions
How small can a QR code be on a business card?+
Print at 2 x 2cm or larger. Below that, module density and printer resolution start to fight each other. A dynamic code keeps the pattern coarse because it encodes a short link instead of your full details.
Will the code on my printed cards stop working?+
No. QR Tool never deactivates codes, free plan included. Public reviews of other platforms describe boxes of cards going dead when a trial ended. Our codes stay live whether you pay or not.
What should the code open?+
A vCard that saves your details straight to their contacts, or a hosted contact page with tap-to-call and email. Both stay editable when the code is dynamic.
