In their own words
Seam
Seam provides an API that developers and businesses can use to connect applications with IoT devices and automate access, energy, and monitoring. It identifies vacation rentals, hospitality, multifamily housing, gyms and sports, and coworking as use cases. The Access Grants API handles PIN codes, mobile keys, key cards, Instant Keys, schedules, and device events. Webhooks deliver access and device updates in a common format across connected brands. Teams can view device status, organize devices by location, and troubleshoot remotely; Seam Bridge links on-premises access systems and offline devices. Its iOS and Android SDKs enable app-based mobile keys for Bluetooth and NFC doors, while web components work with React or plain HTML and CSS and adapt to desktop and mobile interfaces. Seam lists Android, iOS, web, and API platforms and says it connects to thousands of devices and brands, though catalog listings do not guarantee supported integrations. Plans include a free option and paid plans from $5/mo.
Sentry Interactive
Sentry Interactive adds mobile credentials to compatible physical access control systems, letting organizations support phone-based entry without replacing existing reader hardware. A smartphone can act as the NFC reader for tap-to-unlock, and users can also enter by scanning a QR code. iOS and Android widgets provide remote door access, while users can share time-sensitive digital keys. Administrators can apply time, geofence and IP restrictions to credentials and manage tenant, employee and visitor access from a desktop, tablet or smartphone. Sentry says its credentials work with more than 20 physical access control systems and can be embedded in third-party building and management apps. Its SDK also lets other applications, including an organization's own app, add mobile credentials. Smart Access Tiles are passive NFC units placed near doors; they need no batteries, power or cabling and link to the cloud through QR code. The company describes its security approach as using asymmetric cryptography and Zero Trust, with audit logging and privacy regulation compliance. Pricing is on request.
