QRCode.toDataURL('some text',{errorCorrectionLevel:'H'},function(err,url){console.log(url)}) QR Code capacity Capacity depends on symbol version and error correction level. Also encoding modes may influence the amount of storable data.
QRCode.toDataURL('some text', { errorCorrectionLevel: 'H' }, function (err, url) { console.log(url) }) QR Code capacity Capacity depends on symbol version and error correction level. Also encoding modes may influence the amount of storable data. The QR Code versions range from version 1...
Static QR Code: A static QR Code is a type of QR Code that can’t be edited or changed once created. The data it contains is directly embedded in its pattern. If you need to update the data, you’ll need to create a new QR Code. Static QR Codes are non-editable and non-trackabl...

A QR code (quick-response code) is a type of two-dimensional matrix barcode. It uses four standardized modes of encoding: numeric, alphanumeric, byte or binary, and kanji. Its highest storage capacity can be 2,953 bytes. Here is a table about different modes: Input mode Mode indicator Ma...
However, public encoding using QR codes poses a threat to information security. In this paper, we introduce a Two-Level QR code that protects private data by using the recognition patterns of QR codes and by use of polynomial secret sharing algorithms. On a public level, QR codes are ...
This barcode type provides a very high recognition speed and increased encoding capacity. Conceptually, a QR Code can be considered as a means to store information digitally, like flash drives that keep digital data physically. The operations of scanning and decoding can be executed using smartphone...
