I'd like to ask, what is the role of mobile operators (like AT&T,T-Mobile ..) in NFC mobile payment ?

  • They provide secure element(secure SIM card)? NFC enabled mobiles have their own.
  • They enable secure connection? We know cryptography and anyway, basic smart cards don't have internet access and they work great

Why do I need mobile operator for emulation my Visa card on my NFC phone?

thank you!
