System, Device, Product, Apparatus, and Method for Reading Syringe Information

A method comprising:

• receiving, with a first antenna, a first signal from a first RFID tag;
• receiving, with a second antenna spaced apart from the first antenna, a second signal from the first RFID tag;
• determining, with an RFID reader circuit, a first value of a signal parameter associated with the first RFID tag based on the first signal;
• determining, with the RFID reader circuit, a second value of the signal parameter associated with the first RFID tag based on the second signal;
• receiving, with at least one processor, the first value of the signal parameter associated with the first RFID tag and the second value of the signal parameter associated with the first RFID tag;
• and
• determining, with at least one processor, whether the first RFID tag is located between the first antenna and the second antenna.

A system comprising:

• a first syringe;
• a first label including a first RFID tag applied to the first syringe;
• and
• a reader including:
• a first antenna;
• a second antenna spaced apart from the first antenna;
• an RFID reader circuit, wherein the first antenna is connected to the RFID reader circuit, wherein the first antenna is configured to receive a first signal from the first RFID tag, wherein the second antenna is connected to the RFID reader circuit, and wherein the second antenna is configured to receive a second signal from the first RFID tag;
• and
• one or more processors programmed and/or configured to:
• control the RFID reader circuit to determine a first value of a signal parameter associated with the first RFID tag based on the first signal;
• control the RFID reader circuit to determine a second value of the signal parameter associated with the first RFID tag based on the second signal;
• receive, from the RFID reader circuit, the first value of the signal parameter associated with the first RFID tag and the second value of the signal parameter associated with the first RFID tag;
• and
• determine, based on the first value and the second value, whether the first RFID tag is located between the first antenna and the second antenna.
