Receive the clock event
ZKTeco clocks push directly over the local network while Anviz devices synchronize on an automated background schedule.
Capture · Hardware Integration
Every physical punch,
securely landed.
Connect ZKTeco terminals through native push ADMS and poll Anviz devices on your physical LAN—without routing biometric identifiers or attendance records through an external cloud.
Hardware Handshake Verified
Wall-Mounted Biometrics in Action
When employees place a fingerprint or scan an RFID badge at the clock, the terminal communicates directly over the physical LAN to the PunchFlow appliance in milliseconds.
Supported Protocols:
ZKTeco Push ADMS · Anviz TCP
Terminal Buffer:
100,000 Offline Events
Ingress Latency:
< 4ms over LAN
Data Boundary:
100% On-Premise Air-Gapped
A durable path in
Hardware events become trustworthy records.
PunchFlow strictly separates hardware capture from downstream processing. Every physical punch is recorded immediately to a durable, tamper-proof local event journal, ensuring facility power flickers or network maintenance never lose workforce attendance history.
Zero-Loss Resilience Guarantee:
Durable local event journaling preserves original clock timestamps with 100% fidelity.
Automatic failover recovery guarantees complete timecard accuracy.
Secure local journaling
The raw punch event is committed immediately to durable storage before shift matching or overtime calculation.
Map and reconcile
Clock employee IDs are matched to corporate profiles. Unmapped badges are surfaced in an admin triage queue without dropping the punch.
Multiple clock protocols
Support push ADMS and polling models side-by-side within the same appliance instance.
Replayable history
Recover processing safely at any time from the durable raw-punch journal.
No cloud bridge
Clock network traffic and employee biometric data remain entirely inside your firewall.
