Since it is a benefit rather than an admission ticket itself, you do not need to perform an official transfer for the Thunder Pass.
If you purchased the Thunder Pass for someone else or cannot use it on the day, it can be used by someone other than the account holder, provided the benefit has not been used yet.
Once the first entry to the Thunder area is completed with the benefit, it becomes tied to that person, and only they will be able to use it for the rest of the day.
For this reason, please pay close attention to who uses the benefit and do not share your QR code with third parties.
