Contactless access system for the hospitality industry
Cactus Air Touch is a mobile solution developed in 2020 by Cactus Signage, created to support hotels facing operational and safety challenges during the COVID-19 pandemic.
The system enables contactless access to different hotel facilities (gym, spa, restaurant, elevator), replacing physical keys with digital NFC cards accessible from the guest’s smartphone.
