A mobile tag, also known as a QR code, is a two-dimensional barcode that can be scanned by a smartphone or other mobile device to access information, such as a website, video, or contact details. These tags are often used in marketing and advertising campaigns to provide a quick and convenient way for consumers to interact with a brand or product. They have become increasingly popular due to their ease of use and ability to bridge the gap between the physical and digital world. Mobile tags are a powerful tool for businesses to engage with their audience and track the success of their campaigns.
