Re: AMEX and small transaction values
Different merchants have different ways of "connecting" to their bank to process the transaction. Large establishments have a permanent dedicated link to their bank. But smaller merchants connect via a regular telephone line which often uses an 1300 type phone number to dial the bank. That call costs the merchant a fixed flag-fall rate each time a call is made. This is one key reason some smaller merchants do not like to use EFT (not just Amex, but any EFT processing) for small transactions.The whole minimum spend thing always seems like a bit of a wank really, given that the merchant fees are just pro rata and there seems to be no real reason for not taking say $5 on a card. Sure it's maybe 30 seconds of staff time to handle the swiping, but not really so much different to say issuing change from a $20 note or some such. (And, in combination with the first point, if no signature was needed on a very low value transaction it would save everyone some time too).
