-
- They also make money by holding a merchant's deposit until asked to during
- shift-change. Let me illustrate:
-
- 1. A convenience store chain installs card swipers which are connected to a
- given bank.
-
- 2. Purchases are authorized within 30 seconds, as that's how often the
- bank's modem polls the device.
-
- Assume that a management shift change occurs daily at 05:30 hours. When the
- manager logs in to the card-swiper/terminal, it spits out the daily sales
- reports from the previous management shift change, i.e. 8 to 16 hours in the
- past. During that 16-hr period, it's concevable that gas, cigarette, and
- munchie sales will generate $1000 or more in credit card purchases.
-
- Assume that the bank debits the card-holder's account immediately, and
- therefore has use of the funds for up to 16 hours, before the merchant runs
- his report, which _automatically_ "makes" the deposit. The machine then
- responds "AMOUNT CREDITED TO YOUR ACCOUNT."
-
- Multiply that one convenience store by tens of thousands, all using
- card-swipers, and ask yourself how much money the bank gets to play with for
- nothing, then multiply it by anywhere from 8 to 16 hours.
-
- I suspect many millions are quietly diverted this way, with no-one giving it
- much thought. (It didn't occur to me until I went to work for one of these
- stores, and watched the mgr. go through his routine.)
