NFC tags are super low-cost and you can get a tag for just a few cents. The Tags are available in various forms and wearables. You can check the Tag that suits your purpose and order them on sites like Amazon.

Definitely! If you have used NFC Tag for a campaign and you no longer want to run that campaign, you can erase the writing using the free NFC writing App and Rewrite it with your New Campaign URL

QR Codes still need you to open your phone and scan for it to work. While NFC’s just need a tap making it operationally more efficient and faster.

Once you print out a QR Code, the same QR code cannot be reused. Whereas in NFC you can use the same NFC tag multiple times and keep rewriting.
