    Following resource identifiers are supported:

    • tag id - The tag's id. This is not guaranteed to be a unique.
    • tag hash - A hash made of several attributes of the tag, this value is guaranteed to be unique.
    • reader id - The reader's physical id. This is not guaranteed to be a unique.
    • reader hash - A hash made of several attributes of the reader, this value is guaranteed to be unique.
    • client name - The name of the touchatag software client from which the tag event occurred. You can set the name of a touchatag client in its options menu.

    Note Touchatag strongly advises developers to use hash values rather than plain id values. Differences between manufacturers of various tags and readers can result in duplicate id values. Hash values are guaranteed unique.
