Contactless check-in is a modern process that allows guests to check into hotels, flights, or events without physical interaction. Instead of standing in line at a reception desk, guests can use their smartphones or kiosks to complete the check-in process. This method often involves scanning a QR code or entering a confirmation number to access their reservation. This technology enhances convenience and safety, especially during health crises. By minimizing face-to-face contact, contactless check-in helps reduce the spread of germs while streamlining the arrival experience. Many businesses are adopting this system to improve customer satisfaction and operational efficiency.
