Things What One Should Consider Before Buying RFID Systems
RFID systems are available in three basic types and if you’re looking for the best RFID systems, you need to know what categories these are. This guide will serve as a useful pointer for things to be considered before buying an RFID system.
Types of RFID Systems
Low-frequency RFID operates at 125 Khz and has a short range for data reading. This requires contact with the reader to capture data. It’s great for student attendance systems, parking management and even card payment.
On the other hand, there are high-frequency RFID which operate at 13.56 MHz and have a short read range too, with specialized and larger readers and tags. These type of radio frequency identification devices have less interference than UHF or ultra high frequency, making them perfect for small-object tagging on automated lines. High speed reading makes it excellent for hospitals and healthcare units.
The UHF RFID operates between 902 and 956 Hz. UHF is the most used option for Auto ID apps due to dropping costs and long read range. UHF also has issues with interference but a well designed system can overcome these.
Passive Or Active
RFID tags comprise an integrated circuit and antenna. The tag comprises protective material holding the pieces together and shielding them from weathering. Employee ID badges, for example, contain RFID tags embedded within. RFID tags come in various sizes and shapes. These can also be either passive of active. Passive systems must be powered by the RFID reader prior to data transmission. Unlike passive tags, active ones have an on-board power supply like a battery, which enables them to transmit data at different times.
The difference, therefore, emanates from RFID tags themselves having a power source or battery. Active tags cost more and are physically larger. These tags also have further read ranges and high speed on account of their own power source. Passive tags involve readers powering the tag and sending the data back to the reader.
Parts of RFID Systems
Each system starts with an RFID tag. This performs as per application type, reading requirements, size constraints etc. Each tag comprises a chip set and an antenna. Unique data for the tag is stored in the chip set. Available security features are also influenced by this. The antenna also permits the chip to receive and transmit data. The larger the antenna, the wider the range.
Once a suitable tag is to be used, a printer is required for encoding this. The RFID printer makes encoding tags easier and permits individuals to print bar-codes on the label as well. Depending on mode of data collection, there are different types of RFID readers.
• Fixed readers are perfect for creating portals for automated reading.
• Mobile readers are like a mobile PC with an RFID antenna and reader – these are for reading tags manually on the move. Mobile readers also have barcode scanning abilities.
• Then there are desktop readers which work with your PC.
Safety and Compliance
While choosing an RFID system, be sure to check if it complies with government rules and regulations. Additionally, the system should safeguard your child against any harmful radiation. For this, you need a safe RFID system that has been tested and monitored for security.
Why Go for Brahma Eye?
Finding the right RFID solution is a challenge. Make it easier by choosing Brahma Eye, the exemplary student attendance system using RFID technology. Brahma Digital also offers Brahma GPS for fleet tracking. Brahma Eye is a safe, secure, tested RFID student attendance system which makes it easy for schools to automate roll-call.
Through a combination of Show-and-Go and Walk-Through technologies, Brahma Eye is an RFID solution that offers 100% success. Brahma Digital is the pioneer in the field of passive UHF RFID technologies. A passive UHF system comprises not just the tag, antenna and reader but also a host PC. In many cases where tags are powered, data is processed and sent on to the host PC. Asset tracking, student management or inventory management can be greatly facilitated through this.
From education to transport, this reliable RFID systems provider covers a wide range, much like the RFID technology it is based on.
