I would like to know if a token given by the VTS (Visa Token Services) is enough to make a contactless payment with a device without battery as a key fob ?
if so is it necessary to use a type NFC tag in particular?
Thanks for the question - I'm working on getting you an answer. In the meantime, take a look at the documentation on the Token Life Cycle Management:
Visa does not support NFC proximity payments.
