The honest comparison between cards and A2A is not the one on the rate card. This episode runs the total cost of ownership on both, then argues against itself about where cards still belong.

Start at transaction level. A €50 debit card payment in Europe: €0.10 interchange, €0.04 scheme fee, €0.20 acquirer markup, €0.10 authorization, €0.05 gateway. €0.39, or 0.78%. The same €50 on credit: €0.55, or 1.1%. Blended at a 60/40 split: €0.45, or 0.9%. For a €10 million merchant that is €90,000 in direct fees.

The same €50 on A2A: €0.25. One fee, 0.5%, no interchange because there is no issuing bank to compensate, no scheme fee because there is no network, no authorization fee, no gateway. €50,000 a year.

A €40,000 difference. Then the interesting part.

Chargebacks: €15-25 per dispute plus 30-60 minutes of staff time, at a 0.25% rate that is €8,750 a year. A2A: €420, because bank authentication makes a post-payment dispute nearly impossible to sustain.

Fraud: €18,000 in detection tooling, €2,000 in 3D Secure, €15,000 in manual review of flagged orders. €35,000 before a single fraudulent transaction lands. A2A: €2,000, and no manual review queue, because there is nothing to review.

PCI: €7,400 a year in assessment, scanning and consulting. A2A: zero. Card data never enters the merchant's systems, so the scope does not apply.

Reconciliation: seven hours a week matching card batches across networks and settlement windows. €13,200. A2A: €3,960, because real-time settlement arrives with complete transaction data.

Float: 2.5 days of receivables at 5% cost of capital. €3,425. A2A: zero. Money is there in seconds.

Then the largest line in the whole model, and the one that appears in no ledger. Fraud filters reject 1.5% of legitimate transactions. On €10 million that is €150,000 in revenue from customers who were real, were declined, and did not retry. A2A false positives run at zero, because the bank either approves or declines its own customer with no intermediary guessing.

Card total: €307,775, or 3.08% of revenue. A2A total: €56,380, or 0.56%.

The counter-argument, made properly. Cards win international, because A2A is regional and SEPA-bound. Cards win credit, because A2A is debit-only and will not extend float. Cards win under €10, where a tap is marginally faster. And cards win wherever a customer is over 60 and simply prefers them. This is why the realistic model is hybrid: 20-30% A2A adoption over two to three years, 70-80% staying on cards, and a 15-25% reduction in total payment cost from the blend.

Also covered: why the North American gap is larger and the infrastructure less mature, what happens to the comparison as interchange regulation compresses card fees, and the honest read that the strategic question is not whether A2A is cheaper - it is - but whether your customers adopt it at a scale that matters.
