从概念上讲，电子商务与众所周知的商业服务并无不同，后者的服务包括像电话银行、“邮购”目录，或通过传真向供应商发送采购订单等。
Conceptually, e-commerce does not differ from well-known commercial offerings such as banking by phone, "mail order" catalogs, or sending a purchase order to supplier via fax.
各种各样的电话服务也不会有，比如通过在账号后面加# 和/或 *来核对银行账户的收支情况，因为这些操作相当于把转义序列传递给银行的计算机。
Various phone services are gone, like checking a bank balance by typing in the account number followed by # and/or *, for these act as escape sequences to the bank computer.
