I think the key is proximity, I believe. Like with a QR code, you could hypothetically take a picture of it and have that QR code be used anywhere. With this, you have to actually be in proximity to use it, I believe, which adds value in some contexts.
There's likely a secure element in these NFC devices, more sophisticated than the common NFC tags. My guess is something similar to the chips in bank cards.

Is it not possible to clone NFC tags?
