Radio Frequency Identification (RFID)
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 in the Apparel Supply Chain can benefit every stage of the process, from manufacturer to distributor to the retailer.
RFID technology is implemented in tracking and passive, non-contact data read/update systems. It uses a transponder, more commonly known as an RF tag, which can be electronically programmed to contain and communicate unique information. This information is read from a distance over radio waves, and can be automatically transferred into tracking software, or similar.
The tags are readable, and can be writable, too. For example, an RF tag attached to a product part can be updated as it travels down the assembly line to update archival systems with live data on its progression.
What makes up an RFID system?
RFID systems contain a number of separate components. These include:
Transponder (or tag)
RF tags are either ‘passive’ or ‘active’. Both types contain unique data, and usually contain a microchip with an antenna attached to it.
The antenna is attached to the tag and picks up electromagnetic waves sent by the Reader.
Reader (also known as an interrogator). The reader sends out electromagnetic signals designed to be picked up by specific tags, prompting a response.
The data received from the RF tags can be automatically transferred into specialist software such as location trackers, or inventory management systems.
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.
Benefits of RFID
RFID can make manufacturing processes almost entirely non-contact. With product tags automatically updated as they move through a factory, the need for human interference and monitoring is massively reduced – this can be a fantastic solution for companies looking to increase productivity, whilst keeping labour costs low.
Healthcare facilities will also benefit greatly from the range of RFID technology VisionID has to offer. Our solutions provide them with the ability to effectively track assets both inside and outside of the facility.
Pairing RFID technology with our range of handheld computers, asset management applications, and wireless technology, healthcare facilities are able to experience major increases in productivity through the complete automation of our solutions.
In fact, you’ll find that RFID technology can optimise processes across all industries. Our range of readers and antennae cater to any application, whatever your requirements – with us, you can track and trace fixed assets, stock items, vehicles, and even members of staff.
