Default reader has wiegand26 output,RS232 or RS485 communication protocol.
TCP IP or Wifi can be customized.
Our UHF-105 and UHF-105 UHF long range reader, it support read-write or read-only. With read-write chips,
you can add information to the tag or write over existing information when the tag is within range of a reader,
or interrogator. Read-write tags usually have a serial number that can't be written over.
Additional blocks of data can be used to store additional information about the items the tag is attached to.
Some read-only microchips have information stored on them during the manufacturing process.
The information on such chips can never been changed. Other tags can have a serial number written to it once and then that information can't be overwritten later.
The read range of passive tags (tags without batteries) depends on many factors: the frequency of operation,
the power of the reader, interference from metal objects or other RF devices. In general, low-frequency tags are
read from a foot or less. High frequency tags are read from about three feet and UHF tags are read from 10 to 20 feet.
Where longer ranges are needed, such as for tracking railway cars, active tags use batteries to boost read ranges to 300 feet or more
Different frequencies have different characteristics that make them more useful for different applications.
For instance, low-frequency tags are cheaper than ultra high frequency (UHF) tags, use less power and
are better able to penetrate non-metallic substances. They are ideal for scanning objects with high-water content,
such as fruit, at close range. UHF frequencies typically offer better range and can transfer data faster.
But they use more power and are less likely to pass through materials. And because they tend to be more "directed,"
they require a clear path between the tag and reader. UHF tags might be better for scanning boxes of goods
as they pass through a bay door into a warehouse. It is probably best to work with a consultant, integrator or
vendor that can help you choose the right frequency for your application
Most countries have assigned the 125 kHz or 134 kHz area of the radio spectrum for low-frequncy systems,
and 13.56 MHz is used around the world for high-frequency systems. But UHF RFID systems have only been around since the mid-1990s
and countries have not agreed on a single area of the UHF spectrum for RFID. Europe uses 868 MHz for UHF and the U.S. uses 915 MHz.
Until recently, Japan did not allow any use of the UHF spectrum for RFID, but it is looking to open up the 960MHz area for RFID.
Many other devices use the UHF spectrum, so it will take years for all governments to agree on a single UHF band for RFID.
Government's also regulate the power of the readers to limit interference with other devices. Some groups,
such as the Global Commerce Initiative, are trying to encourage governments to agree on frequencies and output.
Tag and reader makers are also trying to develop systems that can work at more than one frequency, to get around the problem.
Normally if you buy cards from us.the cards have random numbers.
If you need to write the card with your NEW numbers.then We would offer you RFID demo software.
and guide you how to write cards,you could also refer to manual.
Normally,different country have different frequency regulations.
Our UHF reader could work from 860mhz to 960mhz.
RFID uses the low-end of the electromagnetic spectrum.
The waves coming from readers are no more dangerous than the waves coming to your car radio
It is best to install at a 45-degree angle from the horizontal line.
We suggest you test the detecting effct before installment.
