1. A syringe assembly, comprising:
a syringe having a barrel body that extends from a proximal end to a distal end and defines a chamber extending along an axial direction therethrough, a Luer connection at the distal end, and a tip extending from the distal end along the axial direction and defining an outlet in fluid communication with the chamber, wherein the chamber contains a material;
a plunger received within the chamber of the syringe to create a fluid seal within the barrel body;
a tip cap defining a central passage configured to receive a portion of the tip such that the tip cap creates a fluid seal over the outlet;
a tamper evident assembly, comprising:
a tamper evident cap disposed over the tip cap, wherein the tamper evident cap has a main body that defines a proximal end defining an opening, a closed distal end opposite the proximal end along the axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage extending from the opening of the proximal end and configured to receive the tip cap; and
a film including a frangible connection and configured to secure the tamper evident cap to the Luer connection; and
a radio-frequency identification (RFID) tag configured to receive and store data related to the syringe assembly,
wherein the RFID tag includes an integrated circuit, configured to store electronic information thereon, and an antenna operatively connected to the integrated circuit and configured to receive a signal from an RFID reader to cause transmission of at least part of the electronic information from the integrated circuit, and
wherein the frangible connection is configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the Luer connection when the frangible connection breaks while maintaining the tip cap over the outlet of the tip following disengagement of the tamper evident cap.
