These debit cards core ideals are valid, and want to bridge between virtual and real world usage. They have each their selling point. But finally it might not be enough because even traditional normal "co-branded / shared" debit/credit cards are facing an identity crisis; giving points, airmiles, shopping points, branding with football teams - its minor differences that don't add big value or create a wave of paradigm shift.
Without that, the cards can survive, the ICO, the tokens yes. But they won't have the capacity to take-off to a higher level. So do be careful and research further - is it reasonable to invest too much or not into these tokens.
To top it all, DASH came up with a debit card that has no commission taken from the fees.
Still - debit card / credit card - their wings are clipped due to the fact they have compliance with the regulatory board(s) and with the debit card underlying system.
All the best!
