Abstract: The present invention discloses an Omni-Directional QR Code System and Method for Contactless Digital Payment in which a Unified Payments Interface (UPI) payment URI conforming to the National Payments Corporation of India (NPCI) specification is encoded in polar-mapped format distributed across three angularly separated data sectors positioned at 0 degrees, 120 degrees, and 240 degrees on a circular code surface, each sector subtending an arc of not less than 100 degrees. A Central Orientation Node comprising concentric alternating black and white rings forming a rotationally symmetric bull's-eye pattern is embedded at the geometric centre of the circular code surface, enabling scan origin detection and orientation reference from any rotational viewing angle without corner finder patterns. The redundancy architecture ensures that any arc of not less than 100 degrees of the circular code surface visible to a standard smartphone camera contains one complete decodable data sector sufficient for full UPI payment URI reconstruction. The decoding method detects the Central Orientation Node, identifies the best visible sector, extracts polar-mapped module values, applies inverse polar transformation to recover a standard QR data matrix, applies Reed-Solomon error correction at level H, and passes the validated URI to a UPI payment application for transaction initiation. The system is applicable to flat, cylindrical, spherical, wristband, and non-planar surfaces and eliminates the scan alignment requirement of all existing two-dimensional barcode standards. A converter method enables any existing standard QR code to be converted to omni-directional format without loss of payment data. Keywords: omni-directional QR code, UPI payment, Central Orientation Node, geodesic radial encoding, 360-degree scan, contactless payment, polar QR mapping, Reed-Solomon error correction, NPCI, India.
