A mine with existing attendance and location equipment can first assess which reliable personnel, shift, card and passage components should remain, rather than assuming full replacement. The upgrade must join the person verified by iris, the card read at the portal, its current valid assignment and entry permission inside the same passage transaction. Only an approved comparison should request one release from the retained door or gate, followed by physical passage evidence. Retention depends on proven interfaces, data quality, control feedback and site commissioning; compatibility should not be promised in advance.
Inventory the responsibility of existing equipment
- Whether attendance only handles shifts and clock events or also supplies a valid personnel status.
- How the location system owns current person-card assignments and location state.
- How the door or gate receives one release and reports passage state.
- Whether devices have stable identifiers, time sources, networks and interface documentation.
What may be retained
Reliable personnel, shift, location-card and passage components with confirmed interfaces should be evaluated for retention. Retention may still require data exchange, transaction correlation, an added controller or better passage feedback.
Four capabilities to add
- Iris identity verification for the person at the portal.
- Transaction-based comparison of that person with the current assignment of the presented card.
- Admission evaluation and one-time release after all mandatory conditions pass.
- Records and exception handling for decisions, passage outcomes, failures and staffed actions.
Scope by the existing condition
- Reliable interfaces and passage feedback: add iris and the transaction comparison layer.
- Usable data but inadequate passage control: retain master data and add control and feedback.
- Closed interfaces or unreliable assignments: correct the data and prove a limited pilot before claiming compatibility.
Recommended upgrade sequence
- Create an inventory of equipment, data, interfaces and owners.
- Define the transaction identifier and authoritative person-card comparison.
- Pilot valid, wrong-card, no-permission, offline, no-passage and staffed-review cases at one portal.
- Reconcile physical passage with the relevant location state before staged expansion.
Confirm before implementation
- Data quality, update timing, available interfaces and maintenance ownership.
- Existing control signals, one-time release, safety behaviour and feedback.
- The real events that together establish final mine-entry status.
- Biometric collection, access, retention and security governance.
Frequently asked questions
Must the existing attendance system be replaced?
Not necessarily. Evaluate its personnel and shift data and proven interfaces before deciding what to retain, extend or replace.
Does reading a location card and then passing iris verification complete a person-card check?
Only when both events belong to the same passage transaction and the verified person is compared with the card’s current valid assignment.
Can a successful iris check directly increase the underground headcount?
No. Permission, other mandatory checks, physical passage evidence and the relevant location state are also required.
