A few digital check-in / self-service kiosk platforms are commonly known for supporting contactless check-in and being built for 24/7 reliability:

• Adelante Live – kiosk and visitor/self-service check-in with contactless flows.
• KioWare – kiosk management software focused on secure, always-on self-service deployments.

If you want, I can also narrow these down by industry (hotel, healthcare, office lobby, events, student housing) or by whether you need hardware + software versus software only.
