A reader must send commands to the tag to access user memory, a process that .You would need to use passive ultrahigh-frequency (UHF) RFID tags that support writing to user memory. This is part of the Electronic Product Code (EPC) specification, of course, but tags aren’t required to be read-write-capable.
A reader can select tags in the field before inventorying them by issuing a new command, .EPC Gen2 Reader Commands and Q Parameter. Understand memory layout for Gen2 UHF (RAIN) RFID tags including the memory banks for EPC, User Memory, Access and TID along with key commands for security.

This tool will help you translate product-related information into encoded data you can program into the user memory bank of an EPC/RFID tag, following the GS1 EPC Tag Data Standard 1.13. To use the tool, enter your data into the Input Data box.
User Memory. The size of User Memory can vary from 0 bytes to 64 bytes. The cheaper the tag the fewer bytes of user memory it will likely have. What do you do with 64 bytes? To continue with the gallon-of-milk analogy, user memory was originally intended to . opSpec1.setOpSpecID(new UnsignedShort(1)); opSpec1.setAccessPassword(new UnsignedInteger(0)); // We'll read from user memory (bank 3). TwoBitField opMemBank = new TwoBitField("3"); opSpec1.setMB(opMemBank); // We'll read from the base of .User memory can be read and written by RFID readers and is useful for applications requiring extra data storage. Choosing RFID Labels Based on EPC and User Memory. When selecting RFID labels based on EPC and user memory, consider the following factors: EPC Memory Size: The size of the EPC memory determines how many bits are available for . A reader must send commands to the tag to access user memory, a process that takes time and can lower read rates. Because user memory has limited storage capacity, it’s also necessary to compress the data.
You would need to use passive ultrahigh-frequency (UHF) RFID tags that support writing to user memory. This is part of the Electronic Product Code (EPC) specification, of course, but tags aren’t required to be read-write-capable. Easily reading data from RFID tags allows you to identify single items or entire batches of goods simultaneously. To help you understand every element involved, here’s what you need to know about storing and reading data on and from RFID tags.
There are only two writable memory banks on a Gen2 UHF RFID tag – the EPC memory and the user memory. Because the EPC memory bank is the main writable memory on an RFID tag, by default, the RFID reader will read the EPC memory. Data from the TID/USER/RESERVED memory banks, 512bits or more, e.g. 4 to 8K, cannot be read in HID mode. To read TID/USER/RESERVED memory banks, an application must have the host API (Application Program Interface) query the Gen2 RFID Tag TID/USER/RESERVED Memory Bank sections.
