One uses proximity. The other uses a camera. Both can carry the same kind of introduction—if they hold the data rather than a link.
Tap: contact information on the chip.
NFC enables a compatible reader to access information at close range. Reading a direct contact record depends on the phone and software, so test the complete experience before choosing it for your audience.
Scan: contact information in the pattern.
A direct-data QR encodes the actual contact fields in its pattern. A compatible scanner can decode those fields without visiting a website. A QR containing only a URL is different: the linked page still needs connectivity.
Give your QR some breathing room.
More data can mean a denser code. Keep contact fields focused, preserve a clear quiet zone and use strong contrast. Test the final printed size on real phones rather than relying only on a large on-screen preview.
Two routes, one considered card.
Add an optional contact QR alongside NFC when you want a camera-based alternative. Neither route is a blanket guarantee for every device. The best choice is the one tested against the way your audience actually shares contacts.
