Reference Manual
Some RFID tags support both read/write operations, on a page-by-page basis. You may
find it necessary to define your own read/write operation. For reference only, the table
below lists the start page for read/write operation on a number of RFID tags.
Start Page Tag Type Standard
-1 Start from byte 0 of the default page (see below) for all tags
3 Mifare Ultralight ISO 14443A
4 SR176 ISO 14443B
3 ICODE SLI ISO 15693
0 LRI512 ISO 15693
3 SRF55VxxP ISO 15693
0 EM4135 ISO 15693
0 Tag-it HF-I ISO 15693
0 Others ISO 15693
5 ICODE ICODE® (Phillips)
0 Tag-it Tag-it® (TI)
Note: Please refer to the specifications of your RFID tags for memory organization.
7.3.1 READ OPERATION
By default, the RFID tag is read from byte 0 of the default page. However, the default
page, amount of bytes and number of pages of each tag may be different. Specify how
many bytes of data you want to read from the tag.
Generally, the read data is user data obtained from the user block. If you are sure that
the data is to be read from a non-user block, such as the lock block, you need to select
the check box of [Display hex values] first.
7.3.2 WRITE OPERATION
Type the string that you want to write to a tag. By default, the string is written to the tag
from byte 0 of the default page. However, the default page, amount of bytes and number
of pages of each tag may be different. Therefore, the input string will automatically be
truncated to fit into pages, and data may be discarded when it comes to the end of pages
available.
Generally, it will write the input string to the user block, which is free for custom use.
The string will be displayed as “user data”. If you wish to write the string to a non-user
block, such as the lock block, you need to select the check box of [Use hex values] first.
Once you have selected to use hex values for the string, the string length must be even.
For example, if you want to write 0x0A, 0x0B and 0x00 to a tag, the string you input
must be “0A0B00” instead of “AB0”.
