Online card payment is already a one-or-two-click action. Adding BNPL on top removes the last piece of friction — the upfront price — without removing the obligation. Approval is instant, interest is deferred, and one plan can quietly become several.

The danger is structural, not moral. The system is designed so that a portion of next month’s income is already committed before next month begins. Once several plans stack, the person is not buying; they are pre-spending. The provider’s revenue model depends on a fraction of users carrying balances or missing payments — that is not a side effect, it is the product.

The reported statistics make the trap visible. BNPL companies advertise delinquency rates under 1%, but 40% of BNPL users have been late on a payment, up from 34% only two years prior. Late is a softer category than delinquent, which is why the public number stays small while the private picture deteriorates.

The deeper change is to the relationship with money itself. Friction at the checkout was doing protective work that most people did not see — it created a pause where do I want this? could be asked. BNPL erases the pause. The same friction-threshold logic that lets vibe-coding produce charming experiments lets BNPL turn an evening of browsing into next month’s lockup. Friction is not virtue, but it is one of the few honest constraints on consumption — and the systems that remove it are not removing it for the buyer’s benefit.
