To be honest it would be really 'the bank of the free' if bunq would support such wearables from different brands.
Apple Pay is sweet and (when I look at the tutorials on the Rabobank-site) way better then the alternatives, but bunqers should be free to choose a Garmini or Fitbit too.
From my knowledge it's not too hard to implement Garmini and/or Fitbit, not harder then implementing Apple Pay. There is a huge demand and competitors are ahead of bunq on this.
So you girls and guys at bunq: make it so and let us bunqers go, where no one has gone before!
