Secure, Compliant Prepaid Vending — Built on STS Standards
A complete STS-compliant prepaid vending platform that manages secure token generation, multi-channel sales, meter integration, and comprehensive revenue tracking for utility providers and municipalities.
How We Helped A municipal utility provider
The Challenge
The municipality needed a compliant prepaid vending solution that could handle multi-channel sales across USSD, web, mobile app, and physical vendor outlets — while maintaining STS security standards for token generation and preventing revenue leakage.
Our Solution
We built an STS-approved vending platform with encrypted token generation, real-time multi-channel sales, automated vendor commission tracking, and full financial reconciliation. AI agents monitor transaction patterns to detect fraud and anomalies.
STS Vending Capabilities
STS-Compliant Token Generation
Secure, certified token generation following the Standard Transfer Specification (STS) — the global standard for prepaid utility systems. Fully compliant with STS 501 and ISO 2022.
Multi-Channel Vending
Sell prepaid credits via USSD (*120* codes), mobile app, web portal, and authorized vendor outlets simultaneously — all reconciled in real time.
Encryption & Security
End-to-end encryption for token transfer, secure key management, and tamper-proof audit trails. AES-256 encryption at rest and TLS 1.3 in transit.

Frequently Asked Questions
What is STS compliance and why does it matter?+
STS (Standard Transfer Specification) is the international standard for prepaid utility token generation, governed by the STS Association. Compliance ensures your tokens are secure, interoperable, and accepted by all STS-certified meters globally.
What sales channels do you support?+
USSD (*120* codes for any phone), mobile app (Android/iOS), web portal (browser-based), and physical vendor outlets with POS integration. All channels share a single token inventory and reconcile automatically.
How do you handle token security?+
Tokens are generated using STS-certified cryptographic algorithms with hardware security modules (HSM) for key storage. All token transfers are encrypted end-to-end. Our AI agents monitor for replay attacks and fraud patterns in real time.
Can this integrate with our existing billing system?+
Yes. The vending platform sits alongside your existing billing — ingesting tariff data, generating tokens, and pushing sales records back for reconciliation. We integrate via REST APIs, file drops, or direct database connections.
