To execute certification operations on the CA websites, you are recommended to use WIN2000 or XP to get better support for high security components.
6. (Attention: Only by installing SafeSign CSP (Cryptographic Service Provider) application software do you have applicable software for encryption/decryption and authentication security function. Do not use the “Unlock PIN” function of SafeSign CSP to unlock your IC card, otherwise it will cause permanent locking of your card.)
7. You must pay attention to the upper or lower cases of the subscriber code. If you forgot your subscriber code, you must personally bring your original ID card and certificate IC card to reset your subscriber code in a household registration office.

   ※ Generally, the certificate application components would be automatically downloaded upon entering the MOICA website. If you press “Unacceptable” when you see “Security Warning” upon entering the web page, the certificate application components would not be able to automatically download and install.
   ※ If you have installed firewall or anti-virus software, you must first check your PC and network environment to see that externally you are using Port 80 and Port 443 (https). If you are using the IP Sharer on the internet, you are advised to close the IP Sharer before decoding and unlocking the IC card.
   ※ If you still cannot decode and unlock your IC card, please dial 0800-080-117 for toll free customer service.

For security reasons, the system requires you to enter your IC card PIN code while using your certificate. The IC card would automatically be locked if you failed a third time in entering your PIN code. Thus, you cannot properly use your IC card. You must then go to the website: http://moica.nat.gov.tw (Certification Operation/Forget PIN Code/Unlock Card Explanation). Use your subscriber code to unlock your card for normal usage.

Locked card decode is used for unlocking the PIN code. For security reasons, the IC card would be locked and cannot be used after failure for a third time in entering your PIN code. You must then go to the website: http://moica.nat.gov.tw (Certification Operation/Forget PIN code/Locked Card Decode Instructions) and enter the correct PIN code to unlock and restore use of your IC card.
A: Attention: Do not use the “Unlock PIN” function of the SafeSign CSP software to unlock your IC card. It would lock your IC card permanently.
