Students should take the damaged card to the nearest dormitory service station or Campus Housing Service Division office to register both online (https://reurl.cc/oyk0XD) and on paper . 
- Then, on the next business day, bring the newly purchased card and damaged card (note: if the card is lost, balance transfer is not possible) to the CHSD office for balance transfer. The balance will be calculated according to the following formula:
Formula: Most recent top-up balance - [(Date of reporting at dorm service station or office) - (Top-up date)] × 100. If the top-up and damage occur within 24 hours of each other, the entire balance will be transferred.
Example: If the most recent top-up was on October 1st with a balance of NT$1000, and the card malfunctions on October 3rd, reported the same day, then the calculation would be 1000 - [(Oct.3 – Oct.1) × 100] = NT$800, and NT$800 will be transferred to the new card. If reported on 10/4, NT$700 would be transferred.
