VisionID has it’s foundations in RFID technology. Through our extensive knowledge and experience, coupled with an unparalleled level of manufacturer support we can offer an RFID solution for virtually any application. Whether it is LF (125Hz), HF (13.56MHz), UHF (868MHz) or Active Tag technology we aim to ensure a return on investment in an effective, controlled and viable manner.
What is RFID?
RFID uses a transponder (commonly called an RF tag) that is electronically programmed with unique information. This data can then be read from a distance over radio waves. These tags can also be read-write, meaning data can be read from and written to the tag, e.g. production information can be updated on a tag as it progresses down the assembly line. RFID systems consist of a number of components including tags, handheld or stationary readers, data input units and system software. The tags are the backbone of the technology and come in all shapes, sizes and read ranges including thin and flexible “smart labels” which can be laminated between paper or plastic. The significant advantage of all types of RFID systems is the non-contact, non-line-of-sight nature of the technology.
Passive and Active RFID Technologies
Within the RFID arena there are two primary types of technology available, namely Passive and Active.
A Passive tag does not contain a battery. When radio waves from the reader reach the chip’s antenna, the energy is converted by the antenna into electricity that can power up the microchip in the tag. The tag is able to send back information stored on the chip. Today, simple passive tags cost from 20 Cents to several Euros, depending on the amount of memory on the tag and other features.
An Active tag has a transmitter to send back information, rather than reflecting back a signal from the reader, as a passive tag does. Most active tags use a battery to transmit a signal to a reader. However, some tags can gather energy from other sources. Active tags can be read from 300 feet (100 meters) or more, but they are expensive (typically more than €20 each). They’re used for tracking expensive items over long ranges. For instance, the U.S. military use active tags to track containers of supplies arriving in ports.
VisionID have an extensive portfolio of tags and inlays available to cater to any application. From tagging in adverse temperature environments to tagging RF-absorptive materials, such as water-carrying items and metal, right through to traditional “Slap-and-Ship” applications, we can identify and supply the correct tag for the job. We are delighted to offer tag and inlay supplies, as well as finished labels through our partnerships with conversion specialists.
RFID Readers / Antennae
VisionID offer a wide range of readers and associated antennae to suit every application. Whatever your requirement, we can supply the right equipment. We can create a solution to allow you to track and trace fixed assets, stock items, vehicles and even people.
