The pandemic has pushed the hospitality industry to rapidly adopt contactless technology to enhance guest safety and convenience. Mobile check-ins and mobile key/keyless entry allow guests to access their rooms and other hotel areas using their mobile devices, saving time and removing the need for paperwork or waiting in line. Contactless payments, including mobile payments, RFID, NFC, and QR code payments, offer a secure and efficient way for guests to make payments without handling cash, while also minimizing the risk of fraud and errors. Digital tipping allows guests to conveniently tip staff without using cash by accessing QR codes, links, or digital wallets like Apple Pay and Google Wallet. Robotics, including cleaning robots, delivery robots, and concierge robots, offer hotels an efficient and cost-effective solution to staffing shortages while providing personalized and timely services to guests. Finally, in-room technology, including voice-controlled assistants, smart TVs, and mobile device control of room amenities, enables hotels to provide a high-tech and unique experience for guests. By leveraging the latest technologies, hotels can optimize their operations, enhance guest experiences, and boost their bottom line.
