Your biometric device,
already talking to ClassGuru.
Most campuses already own a fingerprint or face reader that nobody has connected to anything. ClassGuru reads it, cleans it and turns it into attendance, parent alerts and reports — without changing how staff use the device.
A punch becomes a record in seconds.
The device stores a raw punch: an ID and a timestamp. ClassGuru pulls new punches on a short cycle, matches the ID to the right student, decides whether it is an entry or an exit, applies your period rules, and writes one clean attendance row. Duplicates and replayed punches are discarded before they reach the register.
- Only new punches are fetched, so the device is never overloaded
- A processing lock prevents the same punch being handled twice
- Manual correction stays available for the days a device is down
- Parent alerts fire from the record, not from the raw punch
Four steps, no staff involvement.
Read
ClassGuru connects to the device database — MySQL on Biomax units, SQL Server on eSSL units — and asks only for punches newer than the last one it saw.
Match
The enrolment number on the device is mapped to a student or staff member. Unmapped IDs are held in a review list rather than silently dropped.
Decide
Your rules apply: first punch of the day, in-out pairing for hostels, late thresholds, half-day cut-offs and period mapping for coaching batches.
Notify
The register updates, the parent app reflects it, and WhatsApp or SMS alerts go out on the schedule you choose — not one message per punch.
Devices we already run in production.
If your model is not listed, send it to us before you buy anything. Most readers that expose a database or an API can be connected.
Biomax
MySQL-backed fingerprint and face units. Connected directly to the device database with incremental reads.
eSSL
SQL Server-backed units, including models whose timestamps carry sub-second precision. Handled without duplicate alerts.
Card and RFID readers
Gate and classroom readers that write to a shared database or export a punch file on a schedule.
Not sure what you own?
Send a photo of the label on the back of the device and the software your vendor installed. We will tell you whether it connects, what it needs, and whether it is worth keeping — including when the honest answer is no.
The other things ClassGuru connects to.
WhatsApp notices
Fee reminders, absence alerts, results and circulars through an approved business number, with delivery status recorded against each message.
SMS gateways
Works with the gateway you already pay for. Templates and sender IDs are configured per institution.
Receipts, report cards and bulk circulars sent from your own institution address.
The parent and student app
The Android app reads the same records staff see, so there is no separate sync to maintain.
Payment collection
Online fee collection through your preferred gateway, with receipts written back into the fee ledger automatically.
Exports and reports
Every register and ledger exports to PDF or spreadsheet, including a date-ranged biometric attendance log for audits.

We check compatibility live on the call, so you know before you commit rather than after.
