I have been living in Korea for more than 7 years but in this hotel, the staff said Foreigner needs to submit a copy of their IDs. I don't know the reason. If someone wanted to collect my personal information, there should have been a separate form for consent to the use of personal data. (PIPA Act, South Korea. 2011).
I don't know who will use my data and for what purpose.
illogical ....
