You can send the user to a URL on the web with the contact information you would have otherwise put in the vCard, or provide a link to a vCard on the page (which then relies on the user's mobile operating system to decode it, rather than the QR Code).

A good rule of thumb is that everything can handle URLs and text, but you can't count on the implementations for other types of content, like vCards.īecause of this unreliability in QR Code reader implementations, we recommend using a URL or text instead of a vCard. Some apps are great and support many different formats - others do not.įor example, QuickMark for iPhone handles all formats nicely Scan, also for iPhone, has a cleaner interface, but can't handle vCards. But while Barcode Producer creates valid barcodes for all different content types, not all mobile QR Code readers can read all kinds of content.

Why don't my vCard QR Codes work on some phones?īarcode Producer creates QR Codes by encoding content into a barcode - this can be a URL, text, or a vCard. To do this, set the error correction level, which can be found in the QR Code advanced options window, to a high or very level, then add your logo and try it with a variety of QR Code readers to see if it still works. The intent is to help with physically damaged codes, but you can also "damage" the QR Code with a logo and it'll still work. QR Codes have a built-in error correction capability, which allows codes to remain scannable even after a portion of the code has been disfigured (or replaced with a logo). You can modify a QR Code to insert a logo that said, you’d need to make the image modifications outside of Barcode Producer with a third-party app (like Photoshop, Illustrator, etc.).
