Actually this illustrates how powerful is the concept of money.
_ In the UK we do not use the phrase "checking account".
_ UK usage is "chequebook account" - but this is uncommon, "current account" is customary.
_ And in the context
may do direct payment from their checking accounts
the phrase that would be used is almost always "bank accounts".
_ Another UK paradox is that many so-called bank accounts are not bank accounts, but are "building society accounts".
Please excuse my pedanticism.
