未输入离线 PIN 时 (EMV)

[英]When Offline PIN is not entered (EMV)

原文 2020-07-08 06:48:06 5 1 emv

I have a terminal that behaves this way, when offline PIN is requested and the user presses enter without typing the PIN it goes on to request online PIN instead.我有一个以这种方式运行的终端，当请求离线 PIN 并且用户在不输入 PIN 的情况下按 Enter 键时，它会继续请求在线 PIN。 I want to know if this is the recommended behaviour.我想知道这是否是推荐的行为。 My team argues that it should fail if the offline PIN is not entered instead of requesting online PIN.我的团队认为，如果不输入离线 PIN 而不是请求在线 PIN，它应该会失败。

This a feature called PIN bypass.此功能称为 PIN 旁路。 What is an additional option is subsequent PIN bypass (which means bypassing all PIN methods if bypass is requested on one of them).另一个选项是后续 PIN 绕过（这意味着如果其中一个请求绕过所有 PIN 方法，则绕过所有 PIN 方法）。 If you have bypass enabled but not subsequent and the next applicable method will be online PIN, it will be requested.如果您启用了旁路但未启用，并且下一个适用的方法将是在线 PIN，则会被请求。

In either case, offline PIN is just one of the cardholder verification methods.无论哪种情况，离线 PIN 码只是持卡人验证方法之一。 Failing in such situation without processing the rest of the CVM List when method has 'Apply succeeding rule when this one fails' bit set would be against EMVCo specs.当方法设置了“在此失败时应用后续规则”位设置时，如果在不处理 CVM 列表的 rest 的情况下失败，则将违反 EMVCo 规范。
