The Flow
How It Works
01
Tap to Identify
An ESP32 fitted with an RC522 reader scans the vehicle's RFID tag as it approaches the gate.
02
Instant Verification
The backend looks up the vehicle account, checks the balance, and deducts the toll fare in real time.
03
Gate Opens
On approval the boom gate lifts automatically. Drivers top up their account anytime via Paystack.
