A Rysan product · RFID Attendance & Child Safety

The RFID school attendance system that texts parents in real time.

Herald is an automatic attendance system for schools. A cheap RFID sticker on each child's backpack, one long-range reader at the gate — and every arrival and departure is logged the moment it happens, with an instant SMS to the parent's phone.

No tapping. No queues at the gate. No app to install, no smartphone required — for the child or the parent. Attendance becomes automatic, dispute-proof, and impossible to forge.

Per child — one sticker, lasts years
The problem

Nobody actually knows when a child arrives.

Paper registers get forged. Tap cards create queues and get forgotten. Parents are left guessing, and schools are left fielding phone calls.

For parents

Constant guesswork

No confirmation their child reached school safely, and no alert if a child leaves early. Just worry.

For schools

Disputes & interruptions

Endless "has my child arrived?" calls, and no dispute-proof record when attendance is questioned.

For both

Systems that add friction

Tap-cards and biometrics make children stop, queue, and remember. At a busy gate, they simply fail.

How it works

One sticker. One reader. Zero effort from the child.

1

Each child wears a passive RFID sticker

A small, cheap tag goes on the backpack, uniform collar, or shoe. No battery, no charging — it lasts for years and costs about ₦300.

2

One long-range reader sits at the gate

A weatherproof reader mounted on a post detects tags from 2–5 metres away — and reads a whole class walking through together, all at once.

3

The child just walks through

No stopping. No tapping. No queue. The local hub logs the arrival or departure with a timestamp the instant they pass.

4

The parent gets a text in seconds

"Chidi arrived at God's Grace School at 7:52 AM." Delivered by SMS to any phone — no smartphone or app required on the parent's side.

5

The school sees everything

A live dashboard shows who's in and who's out, with exportable, timestamped logs that settle any attendance dispute instantly.

Why long-range

Built for a busy gate, not a quiet doorway.

Short-range tap systems were built for one person at a turnstile. Herald was built for 200 children arriving in half an hour.

The SMS alerts can pay for the system.

If a school offers parent SMS alerts at ₦1,000 per child per month, the revenue is shared. The school keeps a share for collecting; Rysan runs the gateway and maintains the system. At scale, the alerts more than cover the hardware.

Questions, answered

What parents and schools ask about Herald.

How do parents know their child arrived at school?

Herald sends an SMS to the parent's phone the moment the child passes the school gate — arrival and departure. It works on any phone that can receive a text. No app, no data, no smartphone.

Does the child have to tap a card?

No. Herald uses long-range RFID: a small sticker on the backpack is detected automatically as the child walks through the gate. No stopping, no queues, nothing for the child to remember.

What happens if a tag is lost or swapped?

Tags are cheap to replace and bound to a single student record. Unrecognised or duplicated tags are flagged to the school immediately.

What does an RFID attendance system cost?

Herald is priced per student per term, with the gate reader installed by us. Email rysantechnologies@gmail.com to join the pilot programme and get pricing for your school.
