What's gonna be the RFID Tags ID for the two different types of plants?

Question

So the problem for me in order to get prepared is, what's the specific RFID tag ID for the white plants and what ID for the purple ones? I know that they are gonna be 1 or 2 but for example are they gonna be like this (00000000000000000000001,00000000000000000000002)? Like this (10000000000000000000000,20000000000000000000000)? Less bytes or more bytes? What's the exact one that I should get in my code? Any more information that I should know about the RFID tags ID in order to be prepared completely?

Thank you in advance

Hello,

We used the NDEF standard, with langage code "en" and text contents "1" or "2".

For example, a white plant ("1") could be:

    # Memory Content:
    [00] * xx:xx:xx xx
    [01] * xx:xx:xx:xx
    [02] + 90 C0 F8 FF
    [03] x E1:10:12:00
    [04] x 01 03 A0 0C |....|
    [05] x 34 03 08 D1 |4...|
    [06] x 01 04 54 02 |..T.|
    [07] x 65 6E 31 FE |en1.|
    [08] x 00 00 00 00 |....|
    [09] x 00 00 00 00 |....|
    [0A] x 00 00 00 00 |....|
    [0B] x 00 00 00 00 |....|
    [0C] x 00 00 00 00 |....|
    [0D] x 00 00 00 00 |....|
    [0E] x 00 00 00 00 |....|
    [0F] x 00 00 00 00 |....|

And for a violet plant ("2"):

    # Memory Content:
    [00] * xx:xx:xx xx
    [01] * xx:xx:xx:xx
    [02] + 90 C0 F8 FF
    [03] x E1:10:12:00
    [04] x 01 03 A0 0C |....|
    [05] x 34 03 08 D1 |4...|
    [06] x 01 04 54 02 |..T.|
    [07] x 65 6E 32 FE |en2.|
    [08] x 00 00 00 00 |....|
    [09] x 00 00 00 00 |....|
    [0A] x 00 00 00 00 |....|
    [0B] x 00 00 00 00 |....|
    [0C] x 00 00 00 00 |....|
    [0D] x 00 00 00 00 |....|
    [0E] x 00 00 00 00 |....|
    [0F] x 00 00 00 00 |....|

Data marked as "xx" is the serial number of the tag, and different for each one.

We used official NXP applications as a reference.

Well I followed your instructions: through the app I wrote the tags to all the pots as plain text, en (English),1 or 2 but the memory content is not the same at the stable characters that are translating the content to text…So am I doing something wrong or if I make the reader recognize the tag from the reader I am ok?
