What is RFID?

RFID is an abbreviation for (Radio Frequency Identification),
and is one type of automatic recognition technology which is expected to be used as a tool for advanced information services, and is also called an IC tag.
In addition to a data carrier such as a barcode, two-dimensional code and magnetic card, automatic recognition technologies
such as an RFID, voice recognition and biometrics are being increasingly introduced as tools to realize improvements in business and security measures.
Technology advancements and product expansion of RFIDs have been remarkable, and RFIDs will take on greater roles in many fields
such as production, logistics, retail sales, service and traffic, and in business applications such as individual identification, traceability, and response to environment.

Features of RFID

Barcodes can be seen in various living scenes. This is also one type of automatic recognition technology.
There are the following differences between RFIDs and barcodes.

Communication distanceUp to tens of meters or more Some cm
Simultaneous reading×
Memory capacityLargeSmall


RF tags are widely utilized in various fields such as production, logistics, retail, services and transportation. Our RF tag technology plays an important role in fields ranging from identification and traceability of small substances, and authenticity control to streamlining of workplaces.
