QR Code Reader

QR Code Reader

While both QR codes and Datamatrix codes are error-corrected and can store more information than 1D barcodes, the main advantage of QR codes is that they are open source, so they are used worldwide and are easy to create.

For this reason, QR code readers are widely used in sectors that require interaction with

the public, such as leisure, where they are used for ticket identification, tourism, where we need to check-in, or retail, where they allow us to link the online and offline worlds, for example, by including a QR code on the label that directs us to an online catalogue or by reading coupons.

Datamatrix Code Readers

Datamatrix codes, unlike QR codes, are used in specialised sectors, as the Datamatrix code is one of the main international standards. It is used especially in sectors where quality controls are very demanding, such as the aerospace, naval, automotive and pharmaceutical industries.

Thanks to the large amount of information they contain and the ability of Datamatrix code 

readers to read damaged codes, readers that can read Datamatrix codes are the most suitable for tracking the traceability of products.

For this reason, many governments and organisations require the mandatory use of such codes, such as the Spanish Agency for Medicines and Health Products (Agencia Española de Medicamentos y Productos Sanitarios).

Unlike fixed readers, handheld QR code and Datamatrix readers are best suited to situations requiring operators with greater freedom of movement. When choosing a 2D code reader on a gun,

we must take into account whether freedom of movement is more important, in which case we will choose a wireless QR and Datamatrix reader, or autonomy, in which case a wired reader will be the most suitable option.

Fixed 2D code readers, such as QR or Datamatrix, are mainly used in applications where the item with the code is the one approaching the reader and not the other way around. This situation is most often found in leisure, retail, receiving, production or order picking lines.

In this type of application, the operator works at a fixed point through which the different elements pass, so the fixed QR and Datamatrix code reader is the best option to be able to work more efficiently with his hands free to handle the packages.
