We proposed a high-capacity optical encryption system based on single-shot-ptychography encoding (SPE) technique and quick response (QR) code. Two QR codes are utilized as date containers, one of which is encoded into random binary images (one is encoded image, another one is key) through ...
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.

HCC2D Code: The High-Capacity Colored 2-Dimensional (HCC2D) Code is a proposed format that increases data density and enables QR codes to handle chromatic distortions. Other types and usages of QR codes include the following: Screenshot QR code generator ...
Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness. ...
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...
Tag barcodes can be much smaller than QR ones because they use different symbol shapes in geometric patterns and multiple colors or tints to embed more information in less space. Microsoft refers to this as a High Capacity Color Barcode (HCCB). A major difference with QR codes is that Micros...
Square QR Code: The classic shape used in most QR Code applications ensures optimum scannability and data capacity Round QR Code: A modern variation ideal for branding and creative designs, can have low scanning accuracy Custom styles: Custom designs, such as logos or objects ideal for marketing...
