expiryDate | The expiry or preparation date and time | The expiry or preparation date and time. | |
currentSWVersion | The Software version associated with the device | The Software version associated with the device, typically only used for devices with embedded software or firmware. | |
lotNumber | The lot or batch number | The lot or batch number. | |
serialNumber | The serial number if available | The serial number if available. | |
carrierAIDC | The machine-readable AIDC string in base64 encoding | The machine-readable AIDC string in base64 encoding. Can correspond to the UDI pattern in devices. | |
carrierHRF | The human-readable barcode string | The human-readable barcode string. Can correspond to the UDI pattern in devices. |

Different resources have different ways to handle “physical instances”
If the resources that represent physical entities were split into a "kind" resource and an "instance" resource, this resource would represent the instance that would be referenced by the "kind" resource. For example, Device would be split into Device ( representing the kind or type of Device ) + ItemInstance ( representing the instance of a Device ).

subject | The identifier of the patient who has devices assigned to | ItemInstance.subject |
