GymAxess vs Sentry Interactive

GymAxess combines hardware and software for gym and studio door access control. Its plug-and-play setup connects readers and locks to a hub, then integrates with a gym’s member management software to check whether members can enter at a given time. Members can use Apple Wallet or Google Wallet, QR codes, barcodes, fobs or cards; the site says no app is required. Wallet onboarding comes by email with instructions and a link to add a membership card. Members must choose either a physical membership card or a digital card, not both at once. Listed capabilities include scheduled access rules, membership validation, mobile credentials, QR or barcode entry and multi-location access. GymAxess says Apple Wallet passes use iCloud binding to link a pass to a personal account and prevent unauthorized use or duplication. The service is listed for Android, iOS and web. A Door License costs €10 per month and a Location License costs €50 per month. QR/barcode and NFC readers cost €300 once each; a hub costs €725 once.

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. Listed platforms are Android, API, iOS and web.
