Systems and methods for enabling user interactions with wireless tags
There is provided a system including a wireless tag reader, a first wireless antenna, a wireless tag including an integrated circuit (IC), a conductive element electronically connecting the wireless tag to the first wireless antenna, a non-transitory memory storing an executable code, a hardware processor executing the executable code to transmit an interrogation signal, receive a tag signal from the wireless tag electronically connected to the first wireless antenna in response to the interrogation signal, the tag signal including a wireless tag identification (ID) uniquely identifying the wireless tag, and determine an interaction by a user with the wireless tag based on the tag signal.
1. A wireless tag comprising:
a planar substrate having a first side and a second side opposite the first side;
a first antenna formed on a first side of the substrate;
an integrated circuit (IC) electronically coupled to the first antenna; and
a first floating connection formed on the first side of the substrate and electronically connected to the IC, the first floating connection completing a wireless tag circuit when grounded using a human body part.
2. The system of claim 1 , wherein the first floating connection completes the wireless tag circuit when directly touched by the human body part or indirectly using a conductive element in contact with the human body part.
3. The wireless tag of claim 1 further comprising:
a second wireless antenna formed on the substrate, the second wireless antenna including a second floating connection for connecting to the first floating connection to form a dipole antenna.
4. The wireless tag of claim 3 , wherein the first wireless antenna and the second wireless antenna are formed on the substrate by one of hand drawing with conductive ink, stenciling using conductive ink, and printing using conductive ink.
5. The wireless tag of claim 1 , wherein the substrate is one of a paper substrate, a plastic substrate, and a fabric substrate.
6. The wireless tag of claim 1 further comprising:
an adhesive disposed on the second side of the substrate.
7. The system of claim 1 , wherein the first floating connection completes the wireless tag circuit when touched by a finger being the human body part, and wherein the first floating connection remains floating and does not complete the wireless tag circuit when not touched by the finger.
