USB免驱双界面读写器S9-BU-13-00带3个PSAM卡座修改密码

修改密码
Change Key
当应用的密钥设置中密钥是可以更改的(密钥的访问权限值为 0-14),这种情况下,可以对
密钥进行修改
The key is changeable only when the value of access authority if between 0x0 and 0xe
密钥修改遵循如下规则:
The rules of changing key: 当密钥的访问权限值设为 0-13 时,当要修改的密钥号与该值不同时,需先验证改权限
值对应的密钥,然后再对要修改的密钥进行修改;
When the value of access authority is between 0x0 and 0x0d, and is different from key
number for updating , you must verify the key correspond to access autority for first;
举例:当前设置的密钥访问权限值为 1,如果要修改密钥 2,需先验证密钥 1
eg.: When the value of access authority is 1, and the value of key number for updating is 2, in
this case,you should verify key 1.
当密钥的访问权限值设为 14(0xE)时,在修改密钥前要先验证该密钥号对应的原密钥,
验证成功后方能进行修改
When the value of access authority is 0xE, the key number for updating should be verified
befor

本文介绍了USB免驱双界面读写器S9-BU-13-00在带有3个PSAM卡座的情况下如何修改密码和密钥。当密钥访问权限值在0-13时,需验证对应密钥;若为14,则需验证原密钥。适用于Windows、Unix、Linux和Android系统。
