Why POS Providers Integrate DRP
Merchant Value Proposition
Offer your merchants dispute prevention, customer loyalty, and operational efficiency—features they increasingly expect from modern POS systems.Competitive Differentiation
Be the first in your market segment to offer cryptographic receipt ownership. Create switching costs for merchants invested in your receipt infrastructure.Network Effects
As issuer adoption grows, merchants will specifically seek POS systems with DRP support. Early integration positions you as the standard.Minimal Development Overhead
Open-source SDKs and clear specifications mean straightforward integration. Most POS systems complete integration in 2-4 weeks.Integration Architecture
Plugin/Extension Model (recommended for marketplaces)
Build DRP as optional plugin that merchants enable in your app marketplace. We provide:- Complete plugin source code templates
- Merchant onboarding flows
- Admin dashboard for key management
Native Integration
Build DRP directly into your POS core. Benefits:- Seamless merchant experience
- Tighter integration with receipt generation
- Premium feature differentiation
Hybrid Approach
Basic DRP support native, advanced features (analytics, customer matching) as premium plugin.Technical Requirements
Receipt Generation
- Convert existing receipt format to JSON-LD schema
- Add cryptographic signing with merchant private keys
- Encrypt with customer public keys from issuer directory
Key Management
- Secure merchant private key storage (HSM recommended)
- Public key distribution to issuer network
- Key rotation protocols
Transmission
- Webhook to issuer endpoints
- Optional: batch processing for high-volume merchants
- Retry logic and delivery confirmation

Week 1-2: Technical discovery and SDK integrationWeek 3-4: Testing and certification with sandbox issuersWeek 5-6: Merchant pilot with 5-10 test merchantsWeek 7-8: Marketplace launch and documentationMost POS systems complete full integration in 2-4 weeks of active development.
Do we need to host any DRP infrastructure?
Do we need to host any DRP infrastructure?
No. DRP is stateless infrastructure. You implement:
- Receipt generation (converting your format to JSON-LD)
- Cryptographic signing with merchant keys
- Encryption with customer public keys
- Webhook transmission to issuer endpoints
How do we handle key management for thousands of merchants?
How do we handle key management for thousands of merchants?
We provide reference implementations for secure key management:
- HSM integration for high-security merchant keys
- Key rotation protocols and automation
- Public key distribution to issuer network
- Recovery procedures for lost/compromised keys
What if receipt transmission fails—do transactions get blocked?
What if receipt transmission fails—do transactions get blocked?
Never. Receipt transmission is asynchronous and non-blocking. Payment authorization completes normally. DRP includes retry logic and delivery confirmation, but transmission failures don’t impact core POS functionality. Merchants can manually resend receipts if needed.
Can we charge merchants for DRP functionality?
Can we charge merchants for DRP functionality?
Yes. While DRP itself is free and open-source, you can monetize value-added features:
- Premium receipt analytics and customer insights
- Advanced matching across customer visits
- White-label receipt wallet apps
- Professional services for enterprise merchants
How does DRP certification work?
How does DRP certification work?
We provide:
- Sandbox environment with test issuers for development
- Compliance verification tools to validate implementations
- Certification badge for compliant POS systems
- Ongoing compatibility testing as protocol evolves
