About This Solution

Quick Answer
It's a tap-and-go attendance solution where employees check in by tapping their phone on an NFC tag placed at the office entrance. It's faster, cheaper, and more secure than biometric scanners, with check-in times under 1 second.
- Instant check-in: tap phone on NFC tag — done in under 1 second
- Ultra-low cost: NFC tags cost $2 each vs $1,500+ per biometric scanner
- Proxy-proof: physical tap requirement ensures the employee is on-site
- Real-time tracking: attendance data appears on the dashboard instantly
- No app opening needed: Android devices respond to NFC tags automatically
Quick Answer
NFC requires physical proximity (within 4cm) making it more secure than QR codes which can be screenshot-shared. NFC is faster (tap vs scan), requires no camera, and doesn't need the app to be open on Android devices.
| Feature | NFC | QR Code |
|---|---|---|
| Speed | < 1 second | 3-5 seconds |
| Security | Physical tap required | Can be screenshot |
| Hardware cost | $2/tag | $0 (printed) |
| App opening | Not needed (Android) | Required |
| iOS support | Requires app open | Full support |
Quick Answer
The software starts at a one-time license fee with NFC tags costing approximately $2 each. This replaces biometric scanners at $1,500+ per door. Contact us for pricing based on your organization's size.
- NFC tags: ~$2 per check-in point (vs $1,500/door for biometric)
- Software: one-time license or monthly SaaS subscription
- Hardware: employees use their own smartphones
- Maintenance: NFC tags last years with zero maintenance
Quick Answer
Implementation takes 1–2 weeks including NFC tag deployment, app installation on employee devices, system configuration, and administrator training. The physical setup (placing NFC tags) takes less than a day.
- Day 1–3: System configuration and NFC tag provisioning
- Day 4–5: Physical NFC tag placement at check-in points
- Day 6–8: Employee device enrollment and app installation
- Day 9–10: Administrator training and parallel run
- Day 11–14: Go-live and monitoring
Quick Answer
Yes, but with a difference: Android devices support background NFC reading (no app opening needed), while iPhones require the app to be open for NFC scanning. Both platforms provide the same security and speed.
- Android: tap phone on NFC tag without opening the app — fully frictionless
- iPhone: open the app first, then tap — adds one extra step but same security
- Both: check-in recorded instantly with timestamp and location verification

Technical & Support
5 questions
Quick Answer
The system uses React Native for the mobile app, Next.js for the admin dashboard, Node.js for the backend API, and PostgreSQL for reliable data storage. NFC communication uses the device's native NFC hardware.
- Mobile: React Native — cross-platform iOS and Android
- Dashboard: Next.js — fast, responsive admin interface
- Backend: Node.js — reliable API server
- Database: PostgreSQL — enterprise-grade relational database
- NFC: Native device hardware via React Native NFC library
Quick Answer
Yes, the system supports unlimited facilities with unique NFC tags per location. The admin dashboard provides a unified view across all sites with location-specific filtering, reporting, and shift management.
- Unique tags per location: each facility has its own NFC check-in points
- Centralized dashboard: manage all locations from one interface
- Per-site reporting: attendance reports filtered by facility
- Shift management: configure different shifts per location
- Roaming employees: support for staff working across multiple sites
Quick Answer
Yes, NFC tags use unique encrypted identifiers that can't be cloned. Check-in data is transmitted over HTTPS, stored in encrypted PostgreSQL databases, and access is controlled through role-based permissions.
- Tag security: unique encrypted IDs that can't be duplicated
- Data transmission: all data encrypted via HTTPS/TLS
- Storage: encrypted PostgreSQL database
- Access control: role-based permissions (admin, manager, employee)
- Audit trail: all check-ins logged with device ID, timestamp, and location
Quick Answer
Yes, you can configure grace periods, shift schedules, overtime rules, notification triggers for late arrivals, and department-specific policies. With source code access, any custom business logic can be implemented.
- Grace periods: set acceptable late arrival windows per shift
- Shift schedules: multiple shift patterns per department
- Overtime rules: automatic calculation based on check-in/out times
- Notifications: alerts for late arrivals, missed check-ins, unauthorized attempts
- Holiday calendars: configure public holidays and leave policies
Quick Answer
Every deployment includes NFC tag provisioning, system setup, employee enrollment support, administrator training, and 3 months of technical support. Extended maintenance plans are available for ongoing updates and support.
- NFC tag procurement and provisioning
- Full system setup and configuration
- Employee enrollment assistance
- Admin training and documentation
- 3 months technical support
- Optional extended maintenance plans
