Edge attachable radio frequency identification tags

A radio frequency identification (“RFID”) tag, comprising:

• a flexible substrate;
• an antenna in communication with a first side of the substrate;
• an RFID chip in communication with the antenna;
• and
• one or more adhesive layers in communication with at least a portion of a second side of the substrate,
• wherein the flexible substrate is configured to fold such that distal ends of the second side of the flexible substrate are in close proximity to, and opposing, one another.

A method, comprising:

• attaching a distal portion of a substrate of a radio frequency identification (“RFID”) tag to an item of commerce;
• folding the substrate approximately at the midpoint to substantially form a U-shape;
• attaching an opposing distal portion of the substrate to the item of commerce,
• wherein the RFID tag includes an antenna attached to an outer surface of the substrate, and a radio frequency identification (RFID) chip in electrical communication with the antenna, and
• wherein the antenna and RFID chip are positioned on the substrate such that when the substrate is folded, the RFID chip and the antenna are substantially on one side of the RFID tag.
