Words that mean something else here

TermWhat you'd assumeWhat it means here
IssuerThe brand on the cardThe bank that holds the BIN, named in the cardholder agreement
BINYour own card rangeThe first 6-8 digits, licensed to one bank; a program usually gets an account range inside the bank's BIN
BIN sponsor, sponsor bankTwo different thingsUsually the same bank. In Visa's rules a "Sponsor" is a member responsible for other members, a different idea
Program managerA job titleThe company running the program: a Third Party Agent to Visa, sometimes a provider of prepaid access to FinCEN, and never a licence
FBO, omnibus, custodial, pooledDifferent accountsOne bank account holding many people's money. The FDIC says "custodial deposit accounts with transactional features"; Chime says "omnibus"
FDIC-insuredThe fintech is insuredThe bank is. Pass-through insurance covers the bank failing, and only if the records meet the FDIC's conditions
LedgerOne recordThe bank's general ledger, the processor's balance or the program's sub-ledger; the system of record is the one that wins a dispute
DebitLinked to a checking accountCash App's card is legally "prepaid debit"; Chime's is linked to a deposit account
ExemptThe card is exemptThe bank is, by asset size. The same card is exempt at one bank and capped at another
InterchangeIncomeOn purchases, yes. On ATM withdrawals and prepaid loads, the issuer pays
MigrationMoving dataA BIN migration (same numbers, new bank), a reissue (new numbers) or a processor conversion (same bank)
Prepaid (Canada)A gift cardOften what a US reader would call a fintech checking account

What surprised me

Placeholders in your voice, drafted from the research and the earlier guides. Rewrite each with your own moment.

"A card program is an API." That was my picture after the sandbox demo: cards in an afternoon. The bank's due diligence, the network's approvals and the plastic set the date, and the code waited on them.

"The bank runs the money." The bank holds it and answers for it, but the books that say who owns which dollar are often ours. Synapse made that concrete for me: the money was at solvent banks, and people still couldn't reach it for months.

"Interchange is a market price." It's a table the network publishes twice a year, and for debit a law caps it for big banks. Whether our bank was under $10 billion mattered more to the business case than anything in the product.

"Leaving a partner is like switching vendors." Here the old BIN keeps receiving disputes for six months after the move, and the network won't release it until it has sat idle for 120 days.

"Canada is the US with different banks." In Canada debit earns almost nothing in stores, so fintech accounts are prepaid cards, which is a different product with a different set of rules.
