QR Code | Vibepedia

QR codes contain data for a locator, an identifier, and web tracking, and use four standardized modes of encoding: numeric, alphanumeric, byte or binary, and kanji. The QR code was initially used in the automotive industry, but it soon gained popularity in other fields due to its ability to store a large amount of data in a small space. QR codes are used by major companies such as Google, Amazon, and Facebook for various purposes including product tracking and customer engagement.
