To deploy RFID in your facility, RFID Accessories are needed. These accessories include cables for hooking up antennas, brackets for mounting readers, and RFID power mappers. To get started with RFID deployment, you should know which RFID accessories you need before you purchase them. This article will walk you through the main types of RFID accessories and what they do. Once you have chosen the type of RFID reader that you need, the next step will be to purchase the appropriate accessories.
Adapter/USB
An RFID adapter/USB allows ID family RFID readers to connect via USB. The RFID USB Adapter uses a FTDI chip and includes an LED or buzzer for successful reads. The reader can be used for a variety of projects, such as for labeling and tracking. If you need a more powerful RFID reader, you can get one for Windows with a higher speed USB port. This adapter is compatible with all devices with USB ports.
The USB version of the RFID reader is small and portable and is often
used in manufacturing applications. It features protection standards of IP 40
and can be easily handled. It can also be integrated with user-written
software. Once installed, the RFID USB DESK Reader can read RFID/Proximity
cards. It can also be integrated with your own software and can generate a
sound upon approaching a transponder. The USB version of the reader also can
customize the front label.
Amplifier
An RFID amplifier can be used to store and read information from an RFID-bearing object, such as a credit card. The device can have a fixed location, and the RFID amplifier stores the information read from the RFID-bearing object in a temporary memory. The information is overwritten when the object is removed from the amplifier. A holder 412 is included for holding the RFID-bearing object, and the switch 414 is activated by the shopper. The RFID amplifier can be attached to a shopping cart 440.
When the RFID amplifier 410 is not in use, the shopper can cancel the
item from his or her shopping list, and the system will calculate his or her
path to the next item on the list. The data system will pause prompting the
shopper for any reason, allowing the shopper to choose whether to continue.
This data system will identify the shopper's location through interactions with
local points of contact. As a result, the RFID amplifier 410 will only be able
to determine the location of a shopper, ensuring that he or she is not mistaken
for the previous shopper.
Antenna Cable
Antenna cables are essential components for the proper functioning of RFID readers. This accessory is crucial to RFID technology because it allows you to attach the tags to any surface. RFID readers are equipped with antennas that can transmit data from the tags to the receiver. The RFID antennas must be connected to the reader and transmitter and must be durable enough to withstand rough handling. Antenna cables are available for all RFID readers and can be purchased separately or with the reader.
RFID readers and antennas work together in RFID systems, so it is essential
to select the right cable for your RFID systems. The cable is used to connect
the reader to the antenna and send signals to the tags. Choosing the right
cable is important because a cable with too short of a length can cause the
sensor to not function properly. Therefore, choose the long cable that can
accommodate the whole RFID system. A cable with a higher rating is more durable
and reliable.
Antenna Multiplexer
An antenna multiplexer is a type of transmit/receive antenna duplexer used in mobile radio telephones for the PCS mobile radio system. The multiplexer includes a transmit signal path 101 with an input and filter 103, and a receive signal path 104 with an output 105 connected to a common antenna connection 107. FIG. 1 shows an antenna multiplexer in more detail.
Antenna multiplexers operate by filtering the incoming signal from the
antenna and the output signal from the power amplifier. They are
transmit/receive duplexers in which the output signal and the input signal pass
through each branch simultaneously. This duplexer is commonly used in TDMA
systems, where signals are time-shifted, and CDMA systems do not use a switch-to-switch
signal path. Both systems face substantial challenges in simultaneous duplex
operation.
Antenna Tuning Board
Antenna tuning is necessary for the correct operation of RFID devices. An antenna tuning board helps to optimize the read range of an RFID device by adjusting the impedance of the RFID tag. Antennas can be of different types, which means they need to be matched properly. To find the perfect antenna, you need to first determine the red zone of your RFID device. Then, you should choose an antenna that has the right impedance.
The ATI tuning board has two settings: single-ended and differential.
The single-ended version is intended for RFID tags, while the differential
version is for RF tags and RFID readers. A TIRIS antenna tuning indicator
contains a guide that outlines the process for tuning antenna and reader
systems. The manual is intended for value-added resellers and systems
integrators. Warnings indicate the procedure to be followed and the conditions
to be met. Failure to follow these instructions can result in permanent damage.
Battery
The batteries used in RFID accessories can come in two types: lithium-ion and lithium-thionyl chloride. Lithium-ion batteries offer high energy density and long shelf life. Lithium-thionyl batteries are rechargeable but do not provide long-term performance. The batteries in active RFID tags are typically replaced every couple of years. They are available separately or in a battery-pack with a rechargeable lithium-ion battery.
The battery-powered passive RFID tags use an internal battery to send
their signal. They have a range of 100 meters in an ideal environment. These
tags are more expensive than the active variety, but do not have the long-range
capability of active RFID tags. If you are interested in a passive RFID tag,
you will want to consider buying the battery-operated variety. The
battery-powered passive version is more expensive, but the range is longer.
