Basics of RFID that you can't ask about now!
An easy-to-understand explanation of the relationship between EPC and GS1 codes! You will be able to understand the basic technologies of barcodes and RFID.
Have you ever seen the barcodes attached to products in stores? This barcode is called the "GS1 code" and is used under a common set of rules worldwide. Recently, a new technology called RFID has started to be utilized as an alternative to this barcode. Are you familiar with the EPC system used by RFID? This time, I will explain the terms EPC and GS1 code and their relationship. ■ What is EPC? EPC stands for Electronic Product Code, which is an area that stores information used to identify RF tags. The memory capacity of EPC varies depending on the type of IC chip implemented in the RF tag, but generally, 96 or 128-bit chips are used. The information written can be read and written using a reader/writer. ~ Points to note when writing information to EPC ~ (1) Write in hexadecimal (note that you cannot directly write letters G-Z or symbols). (2) Write information that fits within the memory capacity of the EPC. (3) Write a unique value (a value that is not the same as other RF tags' EPCs).
