These days, there are facilities that require a quarantine pass, so I looked for a quarantine pass. The Korea Centers for Disease Control and Prevention is providing various graphic images well.
If you go to a cafe or restaurant alone, it is possible even for those who are not vaccinated. Depending on the stage of distancing, a quarantine pass is required when gatherings of 4-6 people or more depending on the metropolitan area and non-metropolitan area.
I'm sorry to the self-employed if the level of distancing increases, but it seems that there is no need to use the quarantine pass because we are not together.
Electronic certificates refer to proofs using the COOV app, Naver app, or KakaoTalk.
The PCR test did something and it was a Corona 19 test. A paper certificate or text message arrives, but it is midnight on the 48th day after the expiration date is notified, so it seems to be about two days.
