发行人脚本在Verifone Vx密码键盘上

[英]Issuer Scripts on Verifone Vx PIN pads

Does anyone know how the issuer script processing flow is supposed to work on VeriFone PIN pads? 有谁知道发行人脚本处理流程应该如何适用于VeriFone密码键盘？ As I understand it, the card processor sends back the script(s) in a 9f18 tag. 据我了解，卡处理器以9f18标签发回脚本。 The scripts marked with 71 tag are to be processed prior to the second Generate AC and the one marked with 72 tag are to be processed after. 标记为71标记的脚本将在第二个生成AC之前处理，标记为72标记的脚本将在之后处理。 My question is, what are the sequence of commands, C34, C25 in each case? 我的问题是，在每种情况下，命令序列C34，C25是什么？ I suppose you can have one or more 71s and 72s at the same time. 我想你可以同时拥有一个或多个71和72。 The VeriFone API specification says this: VeriFone API规范说明了这一点：

Re C25: "This command contains the scripts that are received from the host. The script results are returned in the C34 response." Re C25：“此命令包含从主机接收的脚本。脚本结果在C34响应中返回。”

Also, "All scripts need to be initialized by sending a C34 to the PINpad" 此外，“所有脚本都需要通过将C34发送到PINpad来初始化”

So, it's not clear if you send all the C25s, one for each script, and then a C34 or perhaps the 71s before and then the 72s after the C34. 因此，目前尚不清楚你是否发送了所有的C25，每个脚本一个，然后是C34，或者是之前的71s，然后是C34之后的72s。

1 个解决方案

Send multiple C25's as needed, C25 only supports one script at a time. 根据需要发送多个C25，C25一次只支持一个脚本。 Do not try to distinguish the 71 and 72 scripts, just send them. 不要试图区分71和72脚本，只需发送它们即可。 After all the scripts, send the C34. 在所有脚本之后，发送C34。

From the Integrators Guide FAQ section: 从“集成商指南”常见问题部分：

Q: When receiving a 72 script when do we send the C34 to the pinpad? 问：当我们收到72脚本时，我们何时将C34发送到pinpad？
A: C34 is always sent after the C25. 答：C34总是在C25之后发送。 The pinpad will process based on the script before or after the second generate AC. 在第二次生成AC之前或之后，pinpad将基于脚本进行处理。
