Abstract
A radio frequency identification (RFID) tag includes an antenna having a shape providing a machine-readable or human-readable code or symbol. For example, a machine-readable code may comprise a bar code, or other suitable optical code. Human-readable symbols may include, for example, text, alpha-numeric symbols, icons, or pictographs. Using human-readable antenna forms, an RFID tag may be used as a label, for example, to add a distinctive look to the tagged product, to further identify the tag or product it is attached to, or for branding the tag or attached product.
