Question 1

What format does the vCard QR code use?

Accepted Answer

XO QR uses the standardized vCard 3.0 specification, which is natively recognized by Apple iOS Contacts, Google Android Contacts, Samsung Contacts, and Microsoft Outlook.

Question 2

Does the scanner need internet access to save the contact?

Accepted Answer

No! Static vCard QR codes store all contact fields directly inside the QR data matrix itself, meaning contacts can be added even completely offline with no cellular signal.
