RFID Case Study

Category:
Last updated:2020年10月09日

Hello!
This is Nakamura from the Tokyo Development Section.
The cold season is finally approaching, but today I would like to talk about a time when it was very hot.

At the AC2020 private seminar held on Friday, August 21, Paul Whitney, COO of AsReader, Inc. (our wholly owned subsidiary in the US), gave a presentation on overseas case studies.
I am ashamed to admit that I know very little about overseas case studies, so it was very interesting.

The case studies that follow are available at the following URL.

Case 1: RFID in a police station

Case 2: RFID on a farm

Case 1: RFID in a police station

AsReader used: ASR-0240D (A reader that can scan 1D/2D barcodes and HF band RF tags)
*HF band (= short wave) is a type of RFID that can be scanned at a short distance and is used for traffic IC cards.

I heard that the police in the U.S. are using RFID to manage prisoners. I'm suddenly surprised.
First of all, HF tags are installed in the holding area, and barcode bands are attached to the inmates.
Then, by matching the HF tags with the barcodes, it is possible to figure out which inmate is in which holding area.

This system is often used in Japan to manage things, but I was surprised that it could be used to manage inmates.
In his explanation, Paul says, "In a society where crimes are becoming more and more diverse, it is important to make sure that the inmates are housed correctly," which means that in a sense, the system is designed to protect the inmates.

Case 2: RFID on a farm

AsReaders in use: Various types of AsReaders in the LF and UHF bands are in use.
*LF band (=long wave) is an RFID that has been used for a long time, and has the characteristic of not being easily affected by water. It may be good for use with animals such as cows.
*UHF (ultra short wave) band is an RFID that can be read over a longer distance than HF band. When the output power is increased, tags can be read from several tens of meters away. (This depends on the scanning environment.)

It is said that there are 100 million cows in the US. That's amazing.
In order to manage these cows individually, they put LF tags on their ears.
The LF band is not readable over long distances, so they use it together with UHF tags that are readable over long distances.
In the video, there is a part where they replace the reader, which you can see in detail around 4:30 of the following video.

By the way, I have eaten this meat in Japan, and it was very delicious.
I remember that a long time ago, Japanese beef was the best, but I feel that times have changed.

Case 3: RFID in space at the scene of a fire (I put the two together)
AsReader in use: ASR-R250G (This RFID reader can scan long distances even in UHF. 1D/2D barcodes can also be read.)

It is said that one AsReader is attached to each fire engine and is used for equipment management.
It is true that firefighters are in a difficult situation and it is hard to find things when they are buried in ashes. It is very convenient to be able to use RFID to search for things at that time.

I'm also excited to hear that NASA has given permission to use it on the ISS.

As mentioned above, Asterisk is promoting business improvement with RFID on the world stage.
