The Hidden Risks for Fintech Builders 

No-KYC and low-KYC crypto cards are trending again. I’m seeing them framed as “privacy-first” payments – often with the implication that the industry has found a new, durable way to issue cards globally without meaningful onboarding. 

The short version: nothing fundamental has changed. What’s changed is the packaging. 

I’ve been building crypto card infrastructure since 2014, when Wirex issued the first crypto-linked cards. Over the last decade, I’ve watched dozens of no-KYC/low-KYC programmes launch, scale quickly, and then disappear, usually after the same pressure points surface: scheme scrutiny, supervisory attention, and weak compliance plumbing. 

Most of what you’re seeing today falls into two repeatable structures. 

Trick #1: Single-Load Gift Cards 

Think: single-load prepaid gift cards. Load once, spend, done. Visa and Mastercard both offer products like this, most commonly US-issued. 

They often look like regular cards and may support: 

But operationally, they’re a poor substitute for a real consumer card programme: 

• Single-load only (no ongoing account relationship) 

• High decline rates at many merchants and payment flows 

• Balance breakage: you rarely spend the full amount, and the remainder is often stranded 

Because distributors began accepting crypto and stablecoins as the funding method, then marketed the same underlying product as: 

The card didn’t become more sophisticated. The on-ramp did. 

• Distributor margin: typically 3–7% layered on top of top-ups 

• Issuer economics: monetisation of unspent balances (often via inactivity/maintenance mechanics), commonly another 3–5% 

That “leftover balance” isn’t accidental. It’s engineered economics – breakage is the business model. 

Trick #2: Corporate Cards Disguised as Consumer Cards 

This is the more sophisticated, and higher-risk, model. It’s typically marketed as: 

In practice, these are corporate card programmes (or corporate-like BIN programmes) repackaged and resold to retail users. 

Corporate card programmes are structurally different from consumer programmes: 

• Built for business expenses, not personal spending 

• Designed for cross-border distribution (travelling employees and contractors) 

• Typically carry higher interchange potential than standard consumer debit 

• Limits are designed for organisations, not individuals 

• An issuer sets up a corporate card programme, often in offshore or loosely framed jurisdictions (e.g., Puerto Rico, Hong Kong, etc.) 

• Intermediaries repackage the product as a consumer “no/low-KYC stablecoin card” 

• Retail users receive cards with minimal friction and minimal controls: 

  • No travel rule-style friction 

  • No FinProm-style disclaimers 

  • No proof of address 

  • No enhanced due diligence 

  • No behavioural questionnaires 

  • Corporate-grade limits 

I’m based in London. I saw a crypto card ad targeting UK consumers and went through the flow: 

• Onboarding: proof of identity only 

• Deposits: stablecoin top-up with no travel rule checks, no FinProm disclosures, no cooldown 

• The card: HK-issued with a $1M monthly limit 

That’s a corporate limit. Visa does not approve $1M limits for retail cardholders. Full stop. The limit itself is a signal that the programme is not structured like a typical consumer issuance setup. 

• Card fees: users pay for low-friction onboarding and high limits 

• Interchange: materially stronger economics on corporate programmes, especially cross-border 

• FX margin: single-currency USD programmes can generate 2–4% on every non-USD transaction 

When you combine corporate interchange + FX margin + subscription/issuance fees, you get a powerful revenue stack, but one that tends to attract scrutiny quickly when distributed to consumers. 

These programmes all have one thing in common: they don’t last. 

Card schemes and regulators eventually catch up. When they do, shutdowns are rarely graceful. They tend to be: 

If you’re a builder shipping cards through one of these structures, you’re building on infrastructure with an expiration date. 

The question isn’t: “Can I get cards issued quickly?” 

It’s: “Will this programme still be running in 18 months?” 

Compliance infrastructure isn’t a feature. It’s the foundation.
