At this point I should know better than asking why they made it like this, but
I use an i-cash card for all purchases at 7-11 (due to a hectic teaching/research schedule, I tend to shop there daily). Today the clerk asked if I wanted to check it I had won the lottery for the last two months. Process as follows (simpler than the process in the link provided by @slawa, which is also appreciated). Using i-cash provides discounts and points used to get free products. Also, no need for paper receipts.
- Place the card on the scanner (NFC-based, I presume) on the iBon terminal.
- Clerk quickly selects the options (I basically just observed).
- Found it I won 200 NTD.
- Opted to add the 200 clams to my i-cash card balance.
- A paper receipt was printed. I signed and jotted down my phone number.
6. Time to enter my NEW ARC number!
7. Scanned the bar code on the back of my ARC.
8. SUCCESS: Balance on the card immediately increased by 200 bones.
Granted, I hadn’t checked my receipts on the past ten years, so but sure how the old ARC number worked. However, I can confirm that the new ARC number is compatible with the lottery system, say least with the i-cash card method
Wait. You’re supposed to MANUALLY check if you win?
Same with EasyCard, need to check at the terminal if you store receipts digitally, unless you link it with the digital receipts account from the tax office.
As far as I know the terminal will check all your receipts saved on the i-cash (or similar cards). Very hassle-free, if you ask them to “save the receipts” in the card. There may be an automatic notification function of which I’m not aware, but the use of the terminal for checking is quite fast.
Main point: new numbers for the ARC do work for collecting receipt lottery winnings. I think the old ones did too, since I remember winning once back in my “instant noodles every meal PhD dissertation writing days”
It’s the digital age with Taiwanese characteristics.
