Hi there,
Yes I know it doesn’t have wifi, 
my point is they use NFC often to provision a WIFI connection without giving Creds in plain text. Was one application they touted, as well as just a TAG, as it does NOT read using the NFC, You do know that I’m sure.
Should be doable, but you’ll need the NRF_SDK to do anything like that. The Arduino’s BSP’s almost give you NO choice but too.
