Kaam kaise karta hai:

Simply aapko koi bhi qr scanner ka app aapko apne phone me daalna hai. Aur aapko app open karna hai, camera ko qr code ki taraf point karna hai. Aur bas ho gaya aapka kaam. Information directly aapke phone me. Agar static hoga QR code to directly aapke phoen me. Daynamic hoga to url khulega aur aapko aapke shared document par le jayega. Waise aajkal aapko app bhi download karne ki jaurat nahi hai. Aapke phone ke camera me hi ye feature aa gaya hai. Agar aapka camera koi qr detect karta hai to aapko screen par qr code ka symbol bana aa jayega.
