    • A point of sale (POS) device may be configured to locate a payment system and transmit a payment authorization request from a remote location to a payment system, either directly, or via a payment system directory and/or a SSL Gateway. The invention also includes inserting third party account information into an encrypted portion of the payment request, so the payment request appears as a normal request to the issuing bank, but the third party account information may be used by the third party to bill the customer. The payment system directory is further configured to determine one or more payment processors to direct a payment authorization request, such that a single transaction may me allocated among multiple payment processors for authorization. Moreover, the payment system directory is able to format alternative payment methods into a format that is able to be processed over existing payment networks.
    • 销售点(POS)设备可以被配置为定位支付系统,并且直接地或经由支付系统目录和/或SSL网关从远程位置向支付系统发送支付授权请求。 本发明还包括将第三方帐户信息插入到支付请求的加密部分中,因此支付请求以正常请求的形式出现给开证行,但第三方帐户信息可被第三方用于对该客户收费。 支付系统目录还被配置为确定一个或多个支付处理器来指示支付授权请求,使得可以在多个支付处理器之间分配单个交易以进行授权。 此外,支付系统目录能够将替代支付方式格式化为能够通过现有支付网络进行处理的格式。

    • A merchant conducting a transaction on an account forms transaction data with a sensitive data field. To obscure the account prior to transmitting information about the transaction, for each character in the sensitive data field, a combined character is formed with a character of a generated pad. A replacement character is formed by a modulus operation on the combined character and is stored in the corresponding position in the sensitive data field. A transmission containing the sensitive data field with replacement characters is delivered to the merchant's acquirer. Subsequently, a first transmission is received for another transaction from a merchant that contains transaction data upon an account and a sensitive data field. Using the sensitive data field, an attempt is made to retrieve a transaction data record that contains data from a previous transaction that includes the account upon which the previous transaction was conducted. The sensitive data field, which is encrypted as the corresponding account upon which the previous transaction was conducted, was encrypted by a character-by-character modulo operation using a generated pad. If the transaction data record is retrieved, a second transmission is sent that contains a fraud notification of the attempt to conduct a transaction upon the encrypted account in the sensitive data field. If there is no retrieval of the transaction data record, a third transmission containing a no-fraud notification is sent.
    • 在账户上进行交易的商家使用敏感数据字段形成交易数据。 为了在发送关于交易的信息之前模糊帐户,对于敏感数据字段中的每个字符,组合字符与所生成的垫的字符一起形成。 替换字符由组合字符上的模量操作形成,并存储在敏感数据字段中的相应位置。 包含具有替换字符的敏感数据字段的传输被传送给商家的收单方。 随后,接收来自商户的另一交易的第一次传输,该商户包含帐户和敏感数据字段上的交易数据。 使用敏感数据字段,尝试检索包含来自先前交易的数据的交易数据记录,该交易包括进行前一交易的账户。 敏感数据字段被加密为上一次事务处理的相应帐户,并通过使用生成的便签以逐字符模运算进行加密。 如果检索到交易数据记录,则发送第二次传输,其包含在敏感数据字段中的加密账户上进行交易的企图的欺诈通知。 如果没有检索交易数据记录,则发送包含非欺诈通知的第三次传输。
