    ABA ( 6H ): The ID code (the last 6 digits or letters, according to the example "33FFFF") is converted to decimal. The result is "03407871" according to the example, for a total of 8 digits.

    ABA ( 4H ): The ID code (the last 4 digits or letters, according to the example "FFFF") is converted to decimal, and the result is "65535" according to the example, for a total of 5 digits.

    WG26 ( 2H+4H ): The ID code (the last 6th, 5th digits or letters + the last 4 digits or letters, according to the example "33+FFFF") is converted to decimal, and the result is "051" , 65535", a total of 8 numbers.

    WG34 ( 4H+4H ): The ID code (the last 8th, 7th, 6th, 5th, or 5th + last 4 digits or letters, according to the example "5533+FFFF") is converted to decimal, according to The result of the calculation is "21811, 65535" for a total of 10 digits.
