In the most basic format, the UDI would be a coded number registered with standards organizations, and would incorporate a variety of information, including (but not limited to) the manufacturer of the device, expiry dates, the make and model of the device, and any special attributes that the device may possess.[3] In a medical sense, "device" refers to any product that is not pharmaceutical in nature, and while the FDA have been given approval to exempt some devices, Jay Crowely (who was responsible for implementing the UDI requirements in the Act), has expressed an intent to apply the UDI to "everything until somebody gives us good reason not to", (excluding devices which won't need identification).[4]
