Local Processing
All QR code generation, parsing, and EMVCo payload structuring operations are securely processed locally within your browser.
Zero Data Retention
We maintain a strict zero-retention policy for user inputs. Your sensitive Merchant IDs, MSISDN numbers, and payment details are never stored on our external servers.
Optimization & Standards
By default, the rendering engine sets the Error Correction Level (ECL) to Level M (15% recovery capacity). This configuration balances high-density data requirements (such as complex TLV structures) with high-fidelity scan reliability per ISO/IEC 18004 specifications.
