What is a QR Code?

Quick Response (or QR) is a two-dimensional bar code technology that is widely used throughout manufacturing and mobile applications. QR codes can be quickly read from any angle and carry a wide variety of information.  They can be placed on nearly anything and are scanned with a specialized reader or mobile phone application from several inches away. QR technology is a useful tracking application for a variety of mixed assets. It is an easy, low-cost solution that serves multiple use cases.

QR Codes for Construction

Size, Materials and Durability

QR codes come in different sizes to fit any tracking need ranging from handheld tools to large heavy iron. For the extra ruggedness needed in construction, QR codes can be manufactured with a variety of materials—from sturdy aluminum to durable stickers tested to withstand harsh environments. Aluminum tags can be screwed, bolted, tied, or glued to the asset, lasting for many years and under extreme conditions. Durable stickers are weatherproof and versatile, easily affixing to many surfaces.

How are QR Codes Read?

Scanners and Scanner Apps

QR codes can be read with the camera on any mobile device. The camera quickly recognizes the QR code, decodes the information it contains, and provides the information through a link. The same principle is used via apps like ours. The QR code is scanned within the app, the information is decoded and relayed to the equipment tracking system where the scan history is located. The scan history combined with its location information and any other details are then available to the person scanning the code.
