Modernize the Curb.
Start with a Scan.

CurbMeter is a software-defined curb parking platform built for a simpler driver experience and a smarter city operation.

Start parking instantly with CurbMeterQR and CurbMeter Web β€” no app required. For registered drivers, the CurbMeter App combines GPS, Bluetooth and motion sensing to enable intelligent vehicle-exit detection and automatic checkout.

Parking Infrastructure Was Built for Another Era.

Traditional curb parking often depends on meters, embedded sensors, multiple apps, cameras, and costly field maintenance. CurbMeter introduces a lighter architecture designed around secure mobile interaction, connected curb devices, and cloud intelligence.

πŸ—οΈ
Hardware-Heavy Infrastructure
Traditional parking relies on expensive meters and in-ground sensors that require significant capital investment and ongoing maintenance.
🚧
Costly Civil Work
Embedded sensors and wired meters require road cutting, trenching, and extensive construction that disrupts traffic and public space.
πŸ“±
App Fatigue
Drivers face a different parking app in every city. Requiring downloads creates friction and reduces payment compliance.
πŸ“Š
Fragmented Parking & Enforcement Data
Parking, payment, and enforcement systems often operate independently with no unified view of curb activity.
One Platform. Three Ways to Make Curb Parking Easier.

CurbMeterQR
The street-side entry point.
A compact connected curb device that combines Dynamic QR, BLE, location identity, and offline-capable authentication. Designed to deploy with minimal civil work and evolve into a dedicated solar/E-ink curb device.

CurbMeter Web
Scan. Pay. Park. No app required.
Drivers scan the CurbMeterQR code, enter their vehicle, authorize payment, and start parking directly in the mobile browser. No download. No account required to get started.

CurbMeter App
Parking that knows when your vehicle leaves.
For registered users, the CurbMeter App uses GPS, Bluetooth and motion sensing to help distinguish a walk-away from an actual vehicle departure β€” enabling a smarter automatic checkout experience.

From Curb to Checkout in Four Steps
01
Scan
Scan the secure Dynamic QR on CurbMeterQR.
02
Park
Confirm your vehicle and payment in CurbMeter Web.
03
Drive Away
CurbMeter App can analyze vehicle-exit context for registered users.
04
Checkout
The cloud validates the exit event, calculates the session, and completes checkout.
Person Exit β‰  Vehicle Exit
CurbMeter is designed to understand the difference.
A phone leaving a parking zone does not always mean the vehicle left. The driver may simply be walking away. CurbMeter combines multiple signals to understand the context of the departure before triggering automatic checkout.
πŸ“
GPS Velocity
Understand how the device is moving. Speed and trajectory patterns help indicate whether the user is in a vehicle or on foot.
πŸ“Ά
BLE Signal Dynamics
Measure how the phone is separating from the curb device through time-based RSSI behavior. Rapid signal decay suggests vehicle departure.
πŸ”„
IMU Motion Pattern
Analyze motion characteristics to help distinguish walking from vehicle movement. Accelerometer and gyroscope data reveal motion context.

UNKNOWN
⚠️ When the signals disagree, CurbMeter does not guess.
Ambiguous events can remain in an UNKNOWN state for additional validation instead of forcing a premature checkout.
A QR Code That Is Designed Not to Stand Still.

CurbMeterQR uses time-limited Dynamic QR credentials rather than relying on a permanently reusable parking QR. Each token is cryptographically bound to a specific device, zone, and moment in time.

Secure QR scanning with encryption
⏱️
Time-Limited Tokens
Each QR credential expires within seconds. Scanning a photographed or copied code after expiration returns an invalid response.
πŸ”
Cryptographic Signature
Tokens include a cryptographic signature that binds the device identity, zone, nonce, and timestamp into a tamper-resistant payload.
πŸ›‘οΈ
Replay Protection
Server-side nonce validation ensures each token can only be used once. Replayed tokens are automatically rejected.
πŸ“
Device + Zone Binding
Each token is tied to a specific CurbMeterQR device and parking zone. A code from Zone A cannot be used at Zone B.

Start Lighter. Scale Smarter.

CurbMeter is designed to begin with connected curb devices and drivers' smartphones, reducing dependence on extensive road excavation and sensor-heavy installations. Add advanced hardware or AI enforcement only where the operating environment requires it.
