Your Receipts. Your Keys. Your Data.

We have all wanted to download our receipts from our banking apps for quite some time now.

What You Get

Cryptographic Ownership

Your private key lives in your device’s hardware security module—merchants, banks, and even DRP cannot access your receipt data. You control what you share and with whom.

Universal Receipt Wallet

One encrypted receipt format works across all participating merchants and card issuers. Your transaction history travels with you, not locked in bank or merchant apps.

Effortless Expense Management

Corporate card receipts auto-populate expense reports with itemized data. No more photographing paper receipts or manual entry.

Dispute Protection

Cryptographically signed receipts from merchants provide undeniable proof of purchase for chargebacks, returns, and warranty claims.

Privacy by Design

Receipts are encrypted before transmission. Even if intercepted, only you can decrypt the contents with your private key.

How to Access DRP Receipts

For Banking App Users

Your issuer (bank or corporate card provider) integrates DRP into their mobile app. After transactions, receipts appear automatically—decrypted client-side on your device.

For Direct Access

If your bank hasn’t integrated DRP yet, use our open-source reference wallet app to receive and store receipts independently.

Security Architecture

  • RSA-2048 encryption - Industry-standard asymmetric cryptography
  • Hardware key storage - iOS Secure Enclave, Android KeyStore, hardware security modules
  • Zero-knowledge design - Private keys never transmitted or stored on servers
  • Dual signatures - Both merchant and issuer cryptographically sign receipts
  • Retroactive encryption - New encryption layer added at issuer for existing receipt data

Common Questions

Merchants generate receipts but only see what they already know from the transaction. The encrypted version sent to your bank is unreadable without your private key, which only exists on your device.
Your private key is stored in hardware security (iOS Secure Enclave, Android KeyStore) that requires biometric or PIN authentication. Key backup and recovery follows the same secure protocols as your banking app access—if you can recover your banking app, you can recover your receipt keys.
Yes. True ownership means portability. Export receipts in JSON-LD format for tax preparation software, financial analysis tools, or personal record-keeping. Your accountant can import itemized transaction data directly.
Every receipt includes dual cryptographic signatures—one from the merchant and one from your card issuer. Any tampering breaks these signatures, making fraud immediately detectable. This provides stronger proof than paper receipts or email confirmations.
Receipts include itemized line items with descriptions, quantities, prices, taxes, payment method, merchant details, and timestamps. The exact detail depends on what your merchant’s POS system captures, but DRP supports rich itemization beyond traditional credit card statements.
DRP works for both. E-commerce merchants can integrate DRP just like physical retailers. After checkout, encrypted receipts are sent to your banking app the same way, whether you shopped online or in person.
Yes. You can selectively decrypt and export specific receipts to share with employers for reimbursement, with merchants for returns, or with warranty providers. You control what you share and with whom—no one else can access your receipts without your permission.
