The IIN Is the Moat: Why Most Crypto Payment Projects Are Wrappers

#startup #crypto #fintech #payments

Every month, a new "crypto debit card" launches. They all have one thing in common: they're Visa cards.

They settle through Visa's network. They pay interchange. The merchant pays the same 0.3-0.8%. The only difference is what happens before the Visa transaction: your crypto gets converted to fiat.

That's not disruption. That's a wrapper.

What Actually Disrupts Card Networks

To replace Visa, you need three things:

Your own IIN from ISO — Without it, you can't issue cards that terminals recognize
EMV compliance — Without it, your cards don't work at existing terminals
An alternative settlement layer — Without it, you're still using Visa's rails

OpenPasskey has all three.

The IIN

An Issuer Identification Number is the first 6-8 digits of every card number. It's how terminals know where to route a transaction. Visa's IINs start with 4. Mastercard's start with 5.

We applied directly to ISO (International Organization for Standardization) and received our own IIN range. Capacity: 99 billion unique card numbers.

With an IIN, any acquirer can add us to their routing table in approximately one day. The merchant doesn't install anything. They don't sign a new contract. Their terminal just starts recognizing our cards.

Why This Is Hard

Most crypto payment projects skip the IIN because:

They don't know it exists
They don't understand EMV
It's easier to partner with Visa and slap a logo on a card
Building a custom Java Card applet requires firmware expertise most teams don't have

The result: hundreds of "crypto cards" that are really Visa cards with a crypto on-ramp.
