A QR code (Quick Response code) is a type of matrix barcode designed for use on a mobile device’s camera.

QR codes are square in shape and contain a unique pattern of black and white squares.

• Marketing and Advertising: Businesses use QR codes to promote products, services, or events by providing users with exclusive offers, discounts, or access to exclusive content.
• Payment and E-commerce: QR codes enable contactless payments, making transactions faster and more secure.
• Healthcare: QR codes are used in hospitals and medical facilities for patient registration, tracking prescriptions, and storing vaccination records.
• Travel and Tourism: Airlines, hotels, and tourist attractions use QR codes to provide users with travel information, directions, or special offers.
