我抽空给出译文和简要评论。

Billing for goods and
services that customers have purchased is part of any
business.
67)Traditional billing methods in the brick-and-mortar
paradigms are costly and involve generating invoices, stuffing
envelopes, affixing proper postage to the envelopes, and sending
the invoices to the customers. Meanwhile, the
accounts payable department must keep track of incoming payments,
post accounts in the database, and ensure that customer data are
current.


Online stores have many of the same payment collection
inefficiencies as their brick-and-mortar
cousins.
68)Most online customers use credit cards to pay for
their purchases, while auction customers may also use conventional
payments methods, including checks and money orders. Electronic
cash systems, though less popular than other payment methods do
provide several advantages as well as some disadvantages unique to
electronic cash.

69)For the most part, electronic cash transactions are
more efficient and therefore less costly) than other methods, and
that should foster more business, which eventually means lower
prices for consumers. Transferring
electronic cash on the Internet costs less than processing credit
card transactions. You have observed
that conventional money exchange systems require banks, banks
branches, clerks, automated teller machines, and a parallel
electronic transaction system to manage, transfer and dispense
cash. That is expensive.

On the other hand, electronic cash transfers occur
across an existing infrastructure, the Internet, and through
existing computer systems. So the fixed cost of
hardware to handle electronic cash is nearly zero. Because the Internet
spans the globe, the distance that an electronic transaction must
travel does not affect cost. 70)When
considering moving physical cash and checks, distance and cost are
proportional---the greater the distance that the currency has to
go, the more it costs to move it. However, moving
electronic currency from

Detroit to San Francisco costs the same as moving it from
San Francisco to Hong Dong. Everyone can use
electronic cash. Merchants can pay
other merchants in a business-to-business relationship, and
consumers can pay each other. 71)Electronic
cash does not require that one party have any special
authorization, as is required with credit card
transactions.
