Walk in.
Tap.
Paid.
Terminal-less proximity payments for Kenyan merchants.
Your phone identifies the merchant for you. No till number. No QR code. No NFC. Just identify, tap and pay.

PHONE
See the payment happen.
Watch how BlinknPay identifies a merchant and enables payment.
M-Pesa solved moving money.
It didn't solve the checkout moment.
Customers still manually enter merchant till numbers. This creates friction at the critical moment.
Wrong till
One mistyped digit and money goes to the wrong merchant.
Checkout friction
Extra steps during payment mean customers abandon transactions.
Expensive hardware
Traditional terminals cost $40–120. Too much for micro-merchants.
QR dependency
Bad lighting, dirty code, poor connectivity—QR fails too often.
The Real Difference
See how BlinknPay transforms the merchant payment experience.
Traditional Till
Customer: "How do I pay?"
Merchant: "Enter till #8394... No wait, it's 8349..."
Customer: "Let me try again... Did it work?"
Result: Transaction fails. Everyone frustrated.
With BlinknPay
Customer: Walks into shop.
App: Merchant automatically identified via acoustic signal.
Customer: Taps "Pay" button. Done.
✓ Transaction complete in 3–5 seconds.
| Metric | Traditional | BlinknPay |
|---|---|---|
| Checkout Speed | 45–90 seconds | 3–5 seconds |
| Customer Steps | 5+ taps/inputs | 1 tap in app |
| Error Rate | ~2% (wrong till) | <0.1% (encrypted) |
| Merchant Setup | Install POS machine | Already have phone |
So we made the till
identify itself.

The Acoustic Handshake
See how your phone communicates silently with the merchant's—no scanning, no apps, no friction.
How It Works
- 1. Chirp Preamble: Your phone sends a frequency sweep (chirp) that the merchant's device recognizes instantly.
- 2. Authentication: Devices exchange encrypted tokens via ultrasonic audio. No network required.
- 3. Payment: Your app approves the transaction. Done in under 100ms.
How BlinknPay works.
A five-step flow that happens in seconds.
Register
Merchant links their M-Pesa till. BlinknPay device is configured.
Key detail
Full merchant control. BlinknPay does not access the till.
No till numbers to remember
No QR codes to scan
No NFC requirements
Just identify, tap, and pay.
The entire payment flow happens with proximity detection and M-Pesa.
Payments shouldn't require expensive hardware.
Traditional terminals have barriers to entry. BlinknPay removes them.

Lower hardware cost means more merchants can offer digital payments. That expands the entire ecosystem.
Why BlinknPay
Three principles that define our approach.
SIMPLER
No manual till entry. The merchant device broadcasts, the customer phone listens. That's it.
KEY PRINCIPLE
MORE ACCESSIBLE
Designed around smartphones merchants and customers already have. No new hardware constraints.
KEY PRINCIPLE
LOWER COST
A dramatically lower hardware cost than traditional payment terminals puts digital payments within reach.
KEY PRINCIPLE
M-Pesa built the rail.
We are building the interface.
BlinknPay sits above the existing M-Pesa infrastructure as the missing interface layer. We solve the merchant identification problem at checkout.

Receives payment
BlinknPay never touches customer funds.
Funds move customer-to-merchant only.
We are not issuing e-money or wallets.
Security You Can Trust
Built from the ground up with merchant and customer protection at its core.
End-to-End Encryption
All acoustic transmissions are encrypted. No eavesdropping possible—even if someone records the ultrasonic signal.
Chargeback Protection
Customer authentication is verified via encrypted acoustic handshake. Disputes are resolved with cryptographic proof.
Fraud Detection
Real-time transaction monitoring flags suspicious patterns. Machine learning detects and blocks anomalies instantly.
Compliance Ready
Built for Kenya's payment regulations. Full audit trails, KYC/AML integration, and regulatory reporting built in.

Common Security Questions
Can the payment be intercepted?▼
No. All acoustic data is encrypted end-to-end. Recording the ultrasonic signal gives attackers nothing—the encryption keys are exchanged securely and unique per transaction.
What if someone disputes a payment?▼
Every transaction has cryptographic proof of authentication. The acoustic handshake + customer app signature makes disputes rare. When they happen, we have irrefutable evidence.
Is BlinknPay regulated in Kenya?▼
Yes. We're working with Kenya's Central Bank and operate under the Payment Systems Act. Full KYC/AML compliance, audit trails, and regulatory reporting are built in.
Built for how Kenya actually pays.
Starting with Nairobi. Building toward everywhere Kenya's merchants need simpler checkout.
