AFAIK, the difference between the OP's card platform and all others comes down to fees, freedom, and privacy.

..................	OP's eMunie debit card	All others AFAIK
fees	customer: 1 cent * merchant: zero	customer: varies ** merchant: ~1%
freedom	yes	3rd party or govt can block funds
privacy	yes	3rd party or govt can track your purchases.

*(eMunie) customer pays 1 cent per transaction but initial card cost can be ~$4 - $25 depending on if you create it or order it. Card never expires.  Transactions are in native crypto (EMU or one of many token assets) without involving fiat conversion. Speed  < 10 seconds.
**(others) customer has to provide 3rd party info to satisfy AML/KYC regs.  3rd Party conversion required to fiat for merchant along with those fees.
