Note
This method writes a new tag ID to an existing tag.
A valid tag ID must be specified for a tag currently within the field before you can write a new
ID, or if no tag ID is specified, the first tag within the field will be written.
All tag IDs are given in a plain hexadecimal encoded string (i.e., each byte is represented by
a two-letter hexadecimal number).
When writing an EPC class1 Gen2 tag, the password is verified for access rights.
No passwords are required for writing an ISO tag. Please provide an empty string.
