    • A method for providing secure transactions generates a Secure Card Number (“SCN”) for a first entity that is transferred with a first entity identifier to a second entity and then to a money source that verifies that the transaction is valid by use of the first entity identifier and the SCN. The SCN includes a Transaction Information Block (“TIB”) used for invoking one or more restrictions on use of the SCN, a Counter Block, and an encrypted Personal Identification Number (“PIN”) Block. The SCN is transferred to the money source in an account number or a non-account data field. The TIB can be used by the money source to determine which of multiple account numbers associated with the first entity should be used for the first transaction. The money source can also use the TIB to determine whether the device which generated the SCN has a changed status condition, such as a low battery condition or an invalid user entry status. The low battery condition may be determined either by a diagnostic program or by an empirical record of the number of transactions presented for authorization.
    • 一种用于提供安全交易的方法为第一实体产生一个安全卡号(“SCN”),该第一实体用第一实体标识符传送给第二实体,然后通过使用第一实体验证交易是有效的货币来源 实体标识符和SCN。 SCN包括用于调用对SCN的使用的一个或多个限制的事务信息块(“TIB”),计数器块和加密的个人识别码(“PIN”)块。 将SCN转移到货币来源,帐号或非帐户数据字段。 货币来源可以使用TIB来确定与第一实体相关联的多个帐号中的哪一个应该用于第一个交易。 钱源还可以使用TIB来确定生成SCN的设备是否具有改变的状态条件,例如电池电量不足或无效的用户输入状态。 电池电量不足的情况可以通过诊断程序或通过授权授权交易次数的实证记录来确定。
