(Go to English version, public section, scroll down for link to credit report page)
It costs NT$100 for a credit report. I found the staff to be overall very friendly and helpful. If you have trouble filling out the form or understanding your report, ask for Mr. Sun Yi-shin (孫一心).
My only sore spot was a theft/fraud mark one day in June of last year (no charges were made) but they said I could have my credit card company remove that.
One thing that bothers me is that foreigners don’t have a credit score, and it lists the reason for that because you are not an ROC citizen or there’s been an ID number mistake.
Close your browser and re-open it (I used Chrome, for reference)

You’re in. You can see 5 buttons down the side: home, Review Credit Report, History View Record, Email Notification Service, Electronic Invoicing
Click Review Credit Report and choose a Reason for inquiry (default is “Learn about credit history”), tick the box for Credit Score and optionally set a password (default is last 6 digits of ARC ID)
Wait … enter your IC card PIN … wait …
Save the PDF when prompted.
