A prepaid card, not a real-time debit card?
Wasn't this project's entire thing about it being a debit card?
Isn't the whole premise surrounding the supposedly innovative 'CCE module' that it converts cryptocurrency to cash in real time as the transaction is being made in-store?
Otherwise, if all you're offering is a pre-paid card which has to be credited with cash prior to use, then you're really only offering a back-end exchange service with withdrawal of fiat to the card balance account which isn't at all the ground-breaking 'real time' conversion/spending claimed.
Their will be standard PIN to use just like a typical debit card. Your assets are always stored as cryptocurrency. The way CCE works is through its patent-pending technology which when the user swipes it'll convert it into real time fiat to approve the charge and deduct your cryptocurrency as the result of the purchase.
