Vawsum Integrations: Payment Gateways, Biometric Devices and Hardware

Vawsum does not resell payment processing. You hold your own merchant account directly with the gateway or bank, you negotiate your own transaction rates, and settlement goes straight to your institution’s account. Vawsum only carries the instruction. Configuration takes about two minutes: you paste in your merchant key and secret key, and collections begin.

Parents pay by UPI, net banking, debit and credit card, or in cash and card at the school counter. Every mode lands in the same fee ledger, so the cashier’s day-end and the online collection reconcile against one another rather than being totalled separately. Where a payment reaches the gateway but does not post against a student, the cashier captures it in a single step from the payment capture page. Full detail is on the Fee Management System page.

Vawsum currently manages over 100 active biometric devices across client institutions, connected through eSSL’s eTimeTrack and eBIOServer platforms. Punches sync to the cloud automatically, so no one exports a file from the machine at the end of the month.

Three capture methods, one attendance record:

• Fingerprint – the most widely deployed. Cheapest per unit, works without a card, but slows down at peak entry times and struggles with worn fingerprints among older staff and manual workers.
• Face recognition – contactless and faster at a busy gate, unaffected by wet or damaged fingers, and harder to proxy. Costs more per unit and needs reasonable lighting at the mounting point.
• RFID and proximity cards – fastest throughput of the three and ideal where staff pass a gate in a rush. The weakness is that a card can be handed to a colleague, so schools concerned about proxy punching usually pair cards with face recognition on the same device.

What the device choice actually changes. The machine only decides how the punch is captured. Everything after that – grace periods, late-arrival rules, half-day thresholds, auto-absent cutoffs, overtime, leave balances and loss of pay – is handled in software. A school with old fingerprint readers gets exactly the same rules engine as one with new face terminals. That is why we advise institutions not to replace working hardware simply to adopt Vawsum. See the Staff Attendance and Leave Management System for what happens to the punch once it arrives.

A practical note on placement. One device at the main gate is usually not enough for a school with separate teaching blocks – a queue at 7:45am is the single most common reason biometric attendance gets abandoned. Two or three devices positioned at the entrances staff actually use will do more for adoption than upgrading to a more expensive model.

Vawsum’s own bus safety feature is deliberately hardware-free: the bus assistant scans the QR code on each student’s ID card at boarding and alighting, and parents receive four notifications across the day covering both legs of the run. No GPS unit is required for a parent to know their child boarded.

Schools that also want vehicle-level telematics – live location, route replay, speed and driving behaviour, or on-board video – can integrate hardware from MapmyIndia and Streamax. The two answer different questions and are often deployed together:

• MapmyIndia – India-specific mapping and telematics. Strongest where the requirement is accurate route mapping, geofencing around stops, and location data suited to Indian road networks rather than a generic global map layer.
• Streamax – on-board video and MDVR systems. Relevant where the school wants recorded footage inside and outside the vehicle, typically for incident review and driver accountability rather than day-to-day parent communication.

Which do you actually need? Most schools overbuy here. If the question a parent asks is “did my child get on the bus”, QR boarding alerts answer it completely and cost nothing in hardware. GPS earns its place when the school itself needs route compliance and speed monitoring. Video systems earn their place after an incident, or where insurers or the transport authority require them. Buying all three at once, before knowing which question the school is trying to answer, is the usual mistake.

A school notice that only goes out one way reaches only part of the parent body. Some families check the app hourly, some have never installed it, and some share a single basic handset between working parents. Vawsum sends across four channels from the same platform, so the school writes once and the message lands wherever it will actually be read.

Why the mix matters. Schools that rely on push alone quietly lose the families who never installed the app – often the ones the school most needs to reach. Schools that rely on SMS alone pay for every message and lose the ability to send pictures, documents and report cards. Using each channel for what it is good at costs less and reaches more people than picking one and hoping.

Phone numbers stay private. Teachers and parents communicate through the platform rather than by exchanging personal mobile numbers, so a teacher is not fielding messages at eleven at night and a parent is not passing their number around a class group. See Vawsum Connect for how one-to-one and one-to-many communication is structured.
