For travelers who travel through the age of covid-19, they have foreign status in other countries. By registering traveler-specific wearables at the airport, you can record QR code Roger's own information wherever the traveler goes, such as marts and restaurants. At the same time, by collecting periodic thermal checks and traveler's routes, we can quickly take action to protect and protect COVID-19, which we can keep by gathering information from the country of travel, so you can travel healthy. The QR code is a system that can protect the human rights of travelers by displaying the device number in place of the traveler's basic information.
