4.2.5.5 Service
This RFID does not implement the concept of service based on JISX6319-4.
However, it is possible to specify multiple services using a command service list. Table 4-5 shows the
available maximum number of services. When specifying multiple services in the service list, the values of
service list must be set to the same value.

Note: The RFID responds with an error when multiple services are not set to the same service file value.
4.2.5.6 Block
JISX6319-4 uses data of 16-byte blocks. Block number is used to specify each block. Figure 4-9 shows the
block element of 2 bytes and Figure 4-10 shows the block element of 3 bytes. All of bits 6 to 4 of byte D0 for
access mode setting should be set to 0 in this RFID; otherwise the RFID responds with an error.
