Why 4-Digit Store Counter PINs Beat Traditional Wall QRs

Traditional static paper QR codes at retail cash registers suffer from three major vulnerabilities: QR tampering fraud, wrong amount entry by hurried customers, and slow manual cashier confirmation. ### The Counter PIN Solution Every partner store on Nayak Consulting is assigned a memorable 4-digit Counter PIN (like 4921). When the cashier calculates your items, they ring it into the counter portal. You simply type '4921' on your phone, and your exact live bill with vendor name and savings appears instantly. One tap via Razorpay completes payment, the cashier's screen flashes instant green, and your reward points are locked.
