Data Transaction Time (information only)
The communication time with this RFID system can be categorized into two types-data transaction time and
TAT (Turn Around Time).
5.1 Data transaction time
This is a time span needed for data transaction between the IDRW head and ID tag, and will vary depending
on the number of pages subjected to data reading or writing. The actual data transaction time can be
determined from the graphical plotting below and a calculation formula. The number of pages processed N is
a sum of pages defined by a page designation in a command. (In the case of byte write command, the number
of pages covered by a byte write area.)
The maximum allowable pages processed with one command execution is 16 pages for the read, write and
byte write commands and 30 pages for the same write command.
