英文原文:

Nate: OK. I just saw a Versace for thirty dollars. This stuff can't be real!
Gilly: Most of it is. You should sign up.
Nate:I'm not sure I'd want to give these people my credit card number.
Gilly:Didn't you read about PayPal and Bidpay? They are very safe.
Nate:Sure, but it's so complicated. They asked for my credit card authorization number.
Gilly:That's the last three or four numbers on the back of your credit card where your signature is.
Nate:I have trouble understanding all these forms...but I'm sure I'll get it.

参考译文:

奈特：我不确定我是不是要给这些人我的信用卡号码。
吉莉：你没看PayPal和Bidpay的介绍吗？它们都很安全的。
奈特：看了，不过太复杂了。它们还要我的信用卡授权码。
吉莉：那是你信用卡背面号码的末三或四码，就在你签名的地方。
奈特：我看不懂这堆表格……但我想我会弄清楚的。
