@all,
Correct, the "3 bows" are the general sign for NFC.
Items with NFC on the Booomtag platform however, have the logo shown here.
Its a variation, the circle is actually the place under which the tag is located.
I realize the bar picture is not the best example, on the kite/boards and other larger items the logo has text as well but that is not readable on the bar grip hence we left out text there and anticipate on growing recognission.
