Level 1 · App security controls
Checkout context is tied to store policy, customer action flow, and transaction state to reduce tampering risk.
Policy-aware flowContext integrityControlled actions
Security & Verification · Retail-ready trust system
Built for safe,
tamper-resistant checkout.
HosaFlow combines app-level control, verification-floor control, and payment-layer trust to protect store operations and customer confidence.
3-level checkout security
Level 1: App-level purchase context and order integrity
Level 2: Exit-point QR scan and manual verification
Level 3: PCI-compliant gateway processing for payments
Level 2 · Verification floor
Security/store staff scan purchase QR and manually verify item list + quantity before final exit handover.
QR scanManual matchFinal handover
Level 3 · Payment trust
Payments run through store-connected PCI-compliant gateways, aligning processing security with established payment standards.

Security story: from cart to verified exit
Every self-checkout transaction is designed to pass through controlled checkpoints before store exit is approved.
1
Purchase captured
Customer checkout generates transaction context.
2
QR context ready
Purchase QR carries verification reference data.
3
Manual verification
Security team checks items and quantity physically.
4
Approved handover
Only verified purchases are cleared for exit.
Secure login + tamper checks
Security starts before checkout and continues at exit.
PIN-protected operator access and manual verification work together to reduce misuse, identify unpaid items, and keep handover decisions in store control.
PIN and secure-login layer protects sensitive operations and verification actions.
Manual verification finding
Security scan helps identify mismatch or unpaid product before final exit approval.
Audit and review checkpoint
Suspicious checkout behavior can be reviewed and audited with manual floor verification.
Checkout governance controls that reduce misuse risk
Security is not just one feature. It is enforced through configurable limits, role-scoped access, and operational verification discipline.
Item-limit policies based on floor verification capacity
Role-based permissions for owner, manager, and staff
Ability to tighten checkout controls during high-risk windows
Self-checkout can be disabled and fallback operations resumed
Role-audit protection playbook
Every critical action is audit protected by role. If a security issue occurs, the event can be traced to who performed which action, when it happened, and what items were involved.
Owner role
Can review full verification logs, incident history, and escalation outcomes.
Full audit viewEscalation authority
Manager role
Can monitor verification quality, review flagged sessions, and assign follow-up actions.
Flag reviewOperational follow-up
Security/staff role
Performs QR scan and item verification actions that are logged with actor identity and timestamp.
Actor identityTimestampItem verification trace
System audit layer
Preserves verification trail linking transaction context, scanned QR, verified items, and handover decision.
Transaction linkDecision trail
Incident scenario: if security lets unpaid product pass
Example: a security staff member intentionally clears a known person with unpaid items. This can be detected and investigated using role-based audit history.
Step 1
Exit action logged
Who scanned, when scanned, and which checkout context was approved are recorded.
Step 2
Item mismatch trace
Audit compares verified item list against purchase context and highlights anomaly.
Step 3
Role visibility
Owner/manager can see actor-level verification history and linked session details.
Step 4
Escalation handling
Issue can be escalated, reviewed, and operational controls tightened for future prevention.

Payment security and PCI-aligned trust
HosaFlow routes payment through store-configured gateways. Processing security is handled by actual PCI-compliant gateway providers and their compliance controls.
Payments are handled by gateway infrastructure, not custom card storage in storefront flows
Gateway-side PCI compliance standards apply to payment processing
Store chooses supported gateway path and settlement model
Security + payment responsibilities are separated for operational clarity
