What this page is about

Eligibility verification without unnecessary data exposure

AffixIO verifies whether a person, account, device, credential, or holder is eligible for access without exposing unnecessary personal data. Use it for physical doors, secure facilities, digital resource gating, and privileged workflows. You get a binary yes or no and optional proof for audit. Learn more in what is AffixIO, our technical architecture, and compliance pages.

Where it is used

Physical and digital access control use cases

Privacy-first access control and eligibility verification apply across sectors and resource types.

Buildings and workplaces

Eligibility for building entry, floor access, and workplace systems with real-time verification and minimal data.

Secure facilities

Controlled access to secure facilities with stateless, proof-based decisions and audit trails.

Healthcare and public sector

Access control for healthcare and public sector environments where compliance and data minimisation matter. See HIPAA and GDPR alignment.

Education and campus systems

Campus and education access with eligibility verification for dorms, labs, and digital resources.

Merchant and payment linked access

Access gating tied to payment or membership eligibility. Works with offline payment control and merchant flows.

Digital resource gating

Privileged workflows, API gating, and digital resource access based on proof-based verification.

Why AffixIO is different

Privacy-first, stateless, proof-ready access control

Access control verification built for compliance and scale.

Stateless by designNo session or stored state between requests. Each decision is independent.
Privacy-first verificationData minimisation. Binary or proof-based responses. No PII retention.
Binary yes or noClear, machine-readable decisions for access systems and workflows.
Proof-ready auditabilityOptional proof and pseudonymised audit trails for compliance.
Real-time integrationSub-second decisions and real-time connector checks.
Self-hosted or hostedDeploy on your infrastructure or use the hosted API.

How it works

Five-step access control verification flow

Request in, decision and proof out. No session state retained.

01

Request received

Access control system or agent sends a verification request to the AffixIO API.

02

Identifier or token submitted

Identifier or token is submitted with the request. No raw PII required.

03

Rules and connectors checked

Config-driven rules and external connectors are evaluated in real time.

04

Eligibility decided

Eligibility is determined. Optional proof is generated.

05

Binary decision and proof returned

Binary yes or no and optional proof or audit output returned to the caller.

Technical implementation

Access control verification API and deployment

REST API, webhooks, SDKs, and flexible deployment. Low integration overhead.

REST API

Direct HTTP integration for access control and eligibility checks.

Webhooks

Real-time event notifications for audit and downstream systems.

SDKs

Native language support for faster integration.

Self-hosted deployment

Run the verification layer on your infrastructure.

Hosted deployment

Use the hosted API with no infrastructure to manage.

Config-driven rules engine

Define policies and connectors without code changes.

Low integration overhead

Simple request/response contract. Documented and stable.

Compliance and privacy

Compliant access control infrastructure

Designed for data minimisation, auditability, and regulated environments. Do not overclaim certification; align with your own compliance scope.

Data minimisationOnly what is needed for the decision. No unnecessary collection or retention.
Pseudonymised audit trailsAudit logs that support compliance without exposing identity.
Zero unnecessary retentionStateless design. No PII stored for access decisions.
Encryption in transitAll API and connector traffic encrypted.
Support for regulated environmentsArchitecture supports GDPR, CCPA, HIPAA, and LGPD-aware deployments.

FAQ

Frequently asked questions about access control verification

What is physical and digital access control?
Physical and digital access control is the practice of verifying whether a person, account, device, or credential is eligible for access to a building, facility, system, or digital resource. AffixIO provides privacy-first, real-time eligibility verification and binary decisions without exposing unnecessary personal data.
How does eligibility verification work for access control?
A request is received with an identifier or token. AffixIO evaluates rules and connectors, checks external sources where configured, and returns a binary yes or no decision. Optional proof or audit output is available. No session state is retained between requests.
Can access control be privacy-preserving?
Yes. AffixIO is designed for data minimisation. Verification responses are binary or proof-based. No PII is stored. Pseudonymised audit trails support compliance without exposing identity. Suitable for GDPR, CCPA, HIPAA, and LGPD-aware deployments.
What is stateless verification?
Stateless verification means each request is evaluated independently with no server-side session or stored state between calls. The system does not retain identity or eligibility data after the response. This reduces compliance scope and improves security.
Can AffixIO be self-hosted?
Yes. AffixIO supports both self-hosted and hosted deployment. Config-driven rules and connectors allow you to run the verification layer on your infrastructure or use the hosted API.
Does AffixIO store personal data?
No. AffixIO is designed for zero unnecessary retention. Verification is stateless. Audit logs can be pseudonymised. No PII is stored for access control decisions.
Can it integrate with existing access control systems?
Yes. Integration is via REST API, webhooks, and SDKs. Low integration overhead. Config-driven rules engine. Suitable for buildings, IAM, PAM, and digital resource gating.
Is this suitable for regulated sectors?
The architecture supports regulated environments: data minimisation, encryption in transit, pseudonymised audit, and alignment with GDPR, CCPA, HIPAA, and LGPD principles. Specific certification claims depend on your deployment and compliance scope.
