The Check-in Scan platform regulates guest data and stores them to review all data before sending them to the authorities. These data are sent automatically at 11 at night to the corresponding authorities, as the current legislation marks.
The scanning must be done on the back of the documents, scanning the MRZ code of the DNI or passport. Simply frame the camera to capture the data correctly.
In the event that it is impossible to scan the QR code to begin the check-in process, it can always be done manually from the platform itself.
