QR codes have many benefits for businesses and consumers. Businesses can use QR codes to promote their products and services, share contact information, and provide links to their website or social media pages. Consumers can use QR codes to access discounts, coupons, and product information instantly.

Scanning QR codes on Android devices is easy and straightforward. Here are the steps to follow:
