credit card
Let an agent explain credit cards, relay how credit, interest, fees, protections and networks work from consumer finance and regulator sources in general terms, describe the named card products and markets, advise on security and fraud reporting, point people struggling with debt to free debt advice, and distinguish credit cards from debit, charge and prepaid cards, without personal financial advice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.
