Transforming POS Terminals with Privacy-First Compliance

Problem Statement

Brick-and-mortar retailers are under constant scrutiny for collecting and misusing customer personal information.¹ POS systems today often require phone numbers, emails, or loyalty IDs just to deliver invoices.² This practice exposes sensitive data, creating compliance risks under GDPR³, India DPDP Act⁴, CCPA⁵, and PCI DSS.⁶ Customers are increasingly reluctant to share this information due to privacy concerns and targeted marketing abuses.⁷

Retailers today face a critical challenge: balancing the need to collect customer PII (phone numbers, emails) for promotions, invoices, and loyalty programs with strict compliance requirements under GDPR and other privacy laws. Customers are increasingly reluctant to share personal data, fearing misuse and over-collection. This creates friction at checkout, reduces trust, and limits access to valuable insights like purchase history and buying patterns. At the same time, retailers bear the risk of heavy fines, reputational damage, and data breaches. The core problem: How can retailers access actionable customer insights without compromising compliance or customer trust?

Our Solution: Priority-Secured POS

Privitty integrates seamlessly with existing POS systems to deliver privacy-first digital invoices — no phone numbers, emails, or personal identifiers⁸ required. 

How It Works: 

1. QR Code Checkout – Customer scans a QR code at the POS using the Privitty app. 

2. Encrypted Invoice Delivery – Invoice is instantly sent to the app over Delta Chat’s secure protocol. 

3. Zero PII Sharing – No personal details exchanged between customer and retailer. 

4. Granular Access Controls – Retailers set rules for how invoices can be used: 

   • No Forwarding – Stops invoices being shared fraudulently. 

   • No Downloading – Prevents data leakage outside secure storage. 

   • Revocable¹⁰ Access – Retailers or customers can pull back access instantly in case of fraud, disputes, or returns. 

   • Time-Limited Access – Invoices expire automatically after set periods, reducing long-term risk. Ex: Warranty cards, coupons, etc.

5. Comprehensive Compliance – Automatic, immutable audit logs for every invoice and access event¹¹.

Customers

What It Means (Anonymous-Mode KYC)

• Retailers or service providers can still know their customer contextually (purchase behavior, receipts, warranty, loyalty engagement, issue history) without storing PII (phone, email, address).

• Privitty acts as a privacy-preserving communication channel:

  • Retailer ↔ Customer chat, receipts, warranty docs, promotions, support queries.

  • Each user is identified via a pseudonymous token instead of real PII.

• Customers get full transparency and control: revoke, forward, download, expire — so they can manage how long their data lives.

  
  

Example Integrations

1. Point-of-Sale (POS) at Checkout

   • Today: POS usually asks for phone/email to send invoices.

   • With Privitty: Invoice gets pushed to a Privitty ID (anonymous handle). Customer scans QR → invoice securely lands in Privitty Messenger.

   • Retailers “know” this customer by activity, not by phone/email.

2. Loyalty / Rewards Programs

   • Today: Need email/phone to enroll.

   • With Privitty: Loyalty ID = Privitty handle.

   • Customers still get rewards, but retailers never store PII.

3. After-Sales / Support

   • Warranty docs, return approvals, service updates, product manuals sent securely via Privitty.

   • The customer stays pseudonymous. The retailer only knows the context (product, order, issue), not personal details.

4. Financial Services / FinTech Lite KYC

   • Some fintech or insure-tech players need to verify/document usage without exposing sensitive IDs.

   • Privitty could let them send contracts/agreements/OTP equivalents in a pseudonymous secure channel.

     
     

Example User Flow

1. Customer checks out → POS displays QR code.

2. Customer scans QR code with Privitty app.

3. POS sends an encrypted invoice to the Privitty server.

4. Customer opens invoice in Privitty app (view-only).

5. Compliance report generated automatically.
