A QR Code (Quick Response Code) is the next generation 2D barcode developed by Denso Wave in Japan. In that QR code can be text, a URL, or other data. With the help of a QR Code reader software, a smartphone can easily read data in a QR Code and launch the product page.
QR Codes have several advantages over traditional barcodes:
- A QR Code can hold a very large capacity of numbers or letters in any language, including Japanese Kanji
- Small printout size: The printout size of a QR Code can be 1/10 of a traditional barcode.
- Readable from any direction - offers high speed reading
- QR Code has error correction capability (Up to 30% of codewords can be restored in case of dirt or damage)
