标准范围

ISO/IEC 4909:2006建立了使用轨道3的金融交易卡的规范，并且旨在允许基于使用磁条编码信息的交换。它规定了磁道3上读/写信息的数据内容和物理位置，并将与ISO/IEC 7811和ISO/IEC 7812的相关部分结合使用。ISO/IEC 4909:2006认识到需要可以独立于ISO/IEC 7813中定义的磁道2使用或与磁道2结合使用的格式。这种方法旨在允许金融界在促进国际交流方面具有最大程度的灵活性。将轨道3与轨道2结合使用是在线和离线交换环境中的操作模式。这种操作模式要求读取轨道2上的原始编码数据；读取轨道3上的数据；并且，如果需要更新，则重写轨道3上的所有数据。独立使用3号轨道是另一种运营模式，允许在有关各方相互同意的基础上进行在线和离线换乘。它只需要读取轨道3上的数据，如果需要更新，则需要重写轨道3上的所有数据。

ISO/IEC 4909:2006 establishes specifications for financial transaction cards using track 3 and is intended to permit interchange based on the use of magnetic stripe encoded information. It specifies the data content and physical location of read/write information on track 3 and is to be used in conjunction with the relevant parts of ISO/IEC 7811 and ISO/IEC 7812.

ISO/IEC 4909:2006 recognizes the need for formats of track 3 which can be used independently of, or in conjunction with, track 2 as defined in ISO/IEC 7813. This approach is intended to permit the greatest degree of flexibility within the financial community in facilitating international interchange.

Using track 3 in conjunction with track 2 is a mode of operation in both on-line and off-line interchange environments. This mode of operation requires that the original encoded data on track 2 be read; the data on track 3 be read; and, if update is required, all the data on track 3 be rewritten.

Independent use of track 3 is an alternative mode of operation permitting both on-line interchange and off-line interchange based on mutual agreement between interested parties. It requires reading only of the data on track 3 and, if update is required, the rewriting of all the data on track 3.
