Proof of Presence and Attendance Verification

Recent public scrutiny around attendance reporting—most visibly in the childcare sector—has highlighted a growing problem across many industries: how do organizations reliably prove that people were actually present where and when they were supposed to be?

From childcare facilities and home-care providers to cleaning crews, security patrols, and field service teams, attendance is often tied directly to payments, compliance, safety, and trust. When attendance records are weak, incomplete, or easy to manipulate, the consequences can include audits, funding suspensions, reputational damage, and legal exposure.

This is where Proof of Presence becomes essential.

Why Proof of Presence Is Becoming Essential

In many publicly funded or regulated programs, organizations must demonstrate:

• Who was present
• When they arrived and departed
• Where the service was delivered

Historically, this has been handled with paper sign-in sheets, spreadsheets, or manual attestations—methods that are:

• Easy to falsify
• Difficult to audit
• Poorly aligned with modern compliance expectations

As recent events have shown, regulators and funding agencies are increasingly demanding verifiable, tamper-resistant attendance records rather than trust-based reporting.

What Makes a Proof of Presence System Hard to Fake?

A robust Proof of Presence system relies on independent, machine-captured data rather than human memory or manual entry. Two of the most effective data points are:

1. GPS Location of the Scanning Device

• Confirms where the scan occurred
• Can be matched against approved locations (geofencing)
• Provides strong evidence during audits or disputes

2. NFC UID (Unique Identifier) Reads

• NFC tags embedded in ID cards have hardware-level UIDs
• These UIDs are extremely difficult to spoof
• Advanced configurations make impersonation practically impossible

Together, GPS and NFC move attendance verification from “claimed presence” to “provable presence.”

How CodeREADr Supports Proof of Presence

CodeREADr is designed to capture structured, audit-ready data at the moment an action occurs—making it well-suited for Proof of Presence and attendance verification use cases.

Core Capabilities

Secure Check-In / Check-Out

• Supports both check-in only and check-in + check-out workflows
• Automatically timestamps each event
• Prevents illogical sequences (e.g., check-out before check-in)

GPS-Based Location Evidence

• Records GPS coordinates at the moment of scanning
• Supports geofencing to flag out-of-location activity
• Stores location data alongside each attendance event

NFC-Based Identity Verification

• Reads NFC UID from issued cards
• Visually ensures the person checking in is physically present
• Reduces “buddy punching” and credential sharing

Controlled Access

• Unique app-user credentials for scanning
• Role-based permissions for who can record or edit attendance
• Full accountability for every recorded action

Audit-Ready Data

• Immutable scan records
• Exportable logs (CSV, API) for regulators, auditors, or internal review

Childcare Attendance: A High-Visibility Example

In childcare, attendance often determines:

• Subsidy eligibility
• Reimbursement amounts
• Compliance with staffing ratios
• Regulatory standing

With CodeREADr, a childcare provider can:

1. Require staff to authenticate using NFC ID cards (optional but more secure)
2. Record child attendance via barcode or roster-based workflows
3. Capture GPS location automatically at each check-in/check-out
4. Generate daily, weekly, or monthly attendance reports
5. Provide verifiable records during audits or investigations

Instead of paper logs or after-the-fact spreadsheets, attendance becomes objective, time-stamped, and location-verified.

Why This Matters Now

Regulators, funding agencies, and enterprise customers are increasingly unwilling to accept attendance records that rely solely on trust. They want:

• Independent verification
• Consistent data
• Clear audit trails

Proof of Presence is no longer a “nice-to-have.” It is becoming a baseline expectation.

Beyond Childcare: Other Proof of Presence Use Cases

The same approach applies across many industries:

Home Healthcare

• Nurses or aides confirm arrival and departure at patients’ homes
• Supports billing, compliance, and dispute resolution

Cleaning & Facilities Services

• Confirms subcontractors were on-site as contracted
• Verifies frequency and timing of services

Security Patrols

• NFC checkpoints validate completed patrol routes (optional but more secure)
• GPS confirms guards reached required locations

Field Services & Maintenance

• Confirms technicians visited assigned sites
• Documents service delivery for customers and regulators
