Banks could also realized a derived benefit from smart cards?Reverse float.When you load your smart card from a bank account,the bank adds an equal value to its escrow account(委托帐户).As you spend money,transferring value from your smart card to the merchant,that value will ultimately be reconciled with your bank.Your bank pays on demand form the escrow account to keep the system in balance.What happens to the money in the escrow account while the bank waits for you to empty your smart card?It is invested.Suppose you visit the bank on Monday and load your card with $200.The bank credits your smart card with $200 and debits your bank account equally.A debit of your bank account means a credit to the bank’s escrow account.If it takes you two weeks to spend all the money on your smart card,the bank has two weeks to invest that unspent portion of the %200.

银行通过智能卡也可以获得额外的利润?反过来想.当你从银行账户中转入金额到智能卡中时,银行会向其委托账户增加相同的金额.当你花钱的时候,钱从智能卡中转给商户,卡内余额最终会与银行账户持平.银行依靠委托账户的运作保持收支平衡.银行等着你花光智能卡的时候,委托账户里的钱会怎么样呢?这就是投资.假设你星期一到银行给信用卡充值200美元.银行记你智能卡贷方200美元,记你的银行账户借方200美元.你的银行账户借记等同于银行的委托账户贷记.如果你在两周时间里花光了智能卡内所有的金额,银行就有两周时间使用200美金中未使用的部分进行投资.
