What is QR Code?

QR (Quick Response) code is two-dimensional printed barcode, or so-called matrix barcode, that contains information about the item to which it is attached. The code is quickly readable with the camera of mobile phones and tablets. The content for the code can be created easily with QR generator programs that are available also for free from the web.

In SCATMAN applications the QR code usually contains a unique identifier of the item and a link to a web page or a server, so that additional information, like service history, installation instructions, of the item can be retrieved to the mobile device.

QR code is printable even with a normal printer, but for larger quantities and for more demanding environments ordering of the codes as ready-made stickers is recommended. Stickers can be branded for your needs and they are available also in UV resistant and waterproof materials for outdoor use. For harsh environments QR code can be engraved also directly to metal like aluminum and stainless steel plates.

What is NFC?

NFC (Near Field Technology) is a short-range communication technology that enables reading and writing of information from/to a so-called NFC tag with NFC-enabled devices including many of the latest smartphone models. NFC tag is a passive i.e. unpowered chip with a certain amount of memory, and it gets its operation power from the device reading it based on electromagnetic induction. The reading distance is typically only a few centimeters, and in practice the tag is almost touching the reading device.

Like QR codes, NFC tags can contain various information about the item. Data can be written to the tag with mobile application running on NFC-enabled smartphones or with separate programming devices. Opposite to the QR code the NFC tag content can be updated even in the field in by writing new data to the tag, if the tag is not set locked. Each NFC tag contains a unique identifier which makes the copying of the tag content more difficult compared to QR code.

NFC tags are available in various forms varying from branded stickers to plastic encased tags that are highly durable also in harsh environments.
