Description

QR codes are 2D bar codes. They are widely used for their fast readability, high reliability and their large storage capacity compared to ordinary barcodes. EasyQRCode is a robust QR code reading library for industrial applications such as part identification and product or time tracking. These applications typically require the fast and reliable decoding of variable-content QR codes.
EasyQR Code Reading

Automatic Extensive Decoding

The following code types are supported:

  • Data: Kanji, numeric, alphanumeric, byte and mixed FNC1
  • Model 1 QR Codes, all versions (1-14), all levels
  • Model 2 QR Codes, all versions (1-40), all levels
  • GS1 symbology

Print Quality Verification

EasyQRCode inspects the quality of the QR code and computes indicators as defined by the ISO/IEC 15415 and ISO/IEC TR 29158 standards.

EasyQRCode Micro QR Code

Also For Micro QRCodes

Open eVision can also detect and decode Micro QR Codes using its EQRCodeReader class. A more compact version of the regular QR Code, used when less data need to be encoded. Check it with the latest revision of Open eVision Studio & sample programs.

EasyBarCode ECodeReader

ECodeReader: More Codes In One Scan

ECodeReader simplifies the process of reading multiple codes and types within the same image by integrating EasyMatrixCode2, EasyBarCode2 and EasyQRCode into a single, simple, and unified interface. In some applications, reading multiple code types is a requirement. Doing so, required until now, the use of multiple Code Readers (i.e. one per code type). ECodeReader simplifies that process by integrating the power of EasyMatrixCode2, EasyBarCode2 and EasyQRCode into a single, simple, and unified interface. With ECodeReader, you can thus read Barcodes, Data Matrix codes and QR codes with a single method call. Note: ECodeReader requires the EasyMatrixCode, EasyBarCode and EasyQRCode licenses.

Other Benefits

Neo Licensing System

Neo is the new Licensing System. It is reliable, state-of-the-art, and is now available to store Open eVision and eGrabber licenses. Neo allows you to choose where to activate your licenses, either on a Neo Dongle or in a Neo Software Container. You buy a license, you decide later.

Neo Dongles offer a sturdy hardware and provide the flexibility to be transferred from a computer to another. Neo Software Containers do not need any dedicated hardware, and instead are linked to the computer on which they have been activated.

Neo ships with its own, dedicated Neo License Manager which comes in two flavours: an intuitive, easy to use, Graphical User Interface and a Command Line Interface that allows for easy automation of Neo licensing procedures.

DPM - Direct Part Marks

EasyQRCode algorithms have been specifically optimized to read direct part marks. They support the low contrast and distorted codes resulting from dot peening, laser marking, ink jet printing or electro-chemical etching on various materials.

Open eVision Studio

Open eVision Studio is the evaluation, prototyping and development tool of Open eVision.
Its intuitive graphical user interface allows you to call and immediately see the result of any of eVision’s 2D image processing functions. A scripting functionality generates the corresponding code, which can then be copied and pasted into your application.

Open eVision Studio is free (when using Open eVision 2.0 and above) and does not require any license.
