Google performs industry-standard Address Verification System (AVS) and Card Verification Value (CVV) checks to prevent credit card fraud. Google的执行行业标准的地址验证系统 （ AVS标准）及信用卡的验证值 （ cvv ）检查，以防止信用卡欺诈。

The Address Verification System is used to verify the identity of the person claiming to own the credit card. 地址核查制度是用来验证人的身份声称自己的信用卡。 The system will check the billing address of the credit card provided by the user with the address on file at the credit card company.该系统将检查帐单地址，信用卡所提供的用户的地址的文件在信用卡公司。

The Card Security Code (CSC), sometimes also called Card Verification Value or Code (CVV or CVC), is a security feature for credit card transactions, giving protection against credit card fraud.该卡的安全代码 （ CSC ）的，有时也被称为信用卡验证的价值或代码（或cvv的CVC ） ，是一种安全功能，信用卡交易，给予保护，以免信用卡欺诈。

Most debit and credit cards have two card security codes.最扣帐卡及信用卡有两种卡的安全守则。 The first, often called CVC1 or CVV1, is encoded in the magnetic stripe of the card and is used for in-person transactions.第一，通常被称为cvc1或cvv1 ，编码在磁条的卡，是用于在人的交易。 The second, known as CVV2 or CVC2, is used to secure “card not present” transactions occurring over the Internet, by mail, or over the phone.第二，被称为cvv2或cvc2 ，是用来安全的“卡不在场”发生的交易，随着国际互联网，电子邮件，或透过电话。

As Google Checkout processes transactions over the internet I am assuming Google is using CVV2.作为Google Checkout的交易过程中，随着国际互联网，我假设Google是使用cvv2 。 The CVV2 is a 3 or 4 digit value printed on the card, but not available on the magnetic stripe.该cvv2是3或4个数字的价值印载于卡，但并不提供在磁条。 The number is generated when the card is issued, by encrypting the card number and expiry date under a key known only to the issuing bank.有多少时生成的卡发出后，加密卡号码及届满日期下的一个关键只知道向发卡银行。 Supplying this code in a transaction is intended to verify that the customer has the card in their physical possession.提供此代码，以在交易的用意是确认客户有卡在他们的身体藏。

Online merchants who require the CVV2 in their transactions are forbidden from storing these details once the transaction is complete.线上商店谁需要cvv2在他们的交易，禁止储存这些细节，一旦交易完成。 This way, if a database of transactions is compromised, the CVV2 is not included, and the stolen credit card numbers are less useful.这样，如果一个数据库的交易是妥协， cvv2是不包括在内，被窃的信用卡号码是用处不大。
