How buyers usually interpret “credit cards”

People landing here usually already shortlisted C6 Bank and Nubank. The open question is renewal, exit, and whether Inter should stay as a control. Nearby interest we track editorially includes credit cards — use it as a prompt, not as proof.

Two traps that still waste money on credit cards

Trap A — silent renewal. Ask for written proof on C6 Bank before any annual. If the answer is a slide deck, stop.

Trap B — incomplete export. Reproduce the failure on Nubank with the same workload. If Inter is cleaner on that single test, keep it on the sheet.

Field note (Denver)

A freelancer in Denver almost prepaid C6 Bank after a polished demo. They reran the same job on Nubank, captured renew price and cancel URL the same day, and kept Inter as a quiet third column. The annual wait saved a quarter of wasted seats.
