What needs to be defined?

Location, installation, power, connectivity, accessibility and the interface to your access controller or service. Environmental suitability and physical verification must be validated for the intended deployment.

Does a reader replace the access system?

No. The reader supports the verification step. The responsible system retains permission checks and control of the door, service or action. Safety controls and emergency access remain independent.

Product and availability

Reader hardware and deployment configurations are in development. Adding readers to your setup records your intended requirements; it does not confirm a certified installation, stock availability or delivery date.

Pre-order information

Free and non-binding. No payment is taken.

About availability and your request

“Pre-order” means a request to reserve release interest or discuss a project, not a purchase order or contract of sale. Planned arrival in 2027 is a current target, not a guaranteed shipment, installation or service date. Timing, specifications, supported integrations, regional availability and pricing may change. Your request does not guarantee allocation or delivery, and you have no obligation to buy. Final details and any purchase terms will be provided separately before you decide to place a binding order. You may withdraw your request by contacting 4SI.

For software, 2027 refers to the planned product rollout associated with these offerings; existing web access is separate. Installation and Enterprise deployment are confirmed per project.
