Decommissioning

Decommissioning

RFID tag from active use." data-category="Integration">Decommissioning is the process of removing an RFID tag from active service by disassociating its EPC from the linked physical item in the enterprise system. Decommissioning marks the end of the tag's lifecycle in the tracking infrastructure and may optionally include physically disabling the tag using the kill command.

When Decommissioning Occurs

Decommissioning is triggered by several end-of-lifecycle scenarios:

Product sold to consumer: In retail, the tag's tracking function ends at point of sale. The enterprise system records the sale event and marks the EPC as decommissioned. The physical tag may remain on the product but is no longer inventoried.

Asset retired: When a tagged asset (equipment, container, tool) is scrapped or disposed of, the EPC must be removed from the active asset register to prevent phantom inventory counts.

Tag replacement: If a laundry tag or on-metal tag exceeds its operational lifecycle (wash count, mechanical damage), the old EPC is decommissioned and a new tag is commissioned for the same physical item.

Returnable asset recycling: Reusable transport items (pallets, totes, containers tracked by GRAI-96) may be decommissioned when the container is retired, while the tagged item that was inside continues its lifecycle under a different EPC scheme.

Decommissioning Workflow

The standard decommissioning workflow records an EPCIS ObjectEvent with the business step urn:epcglobal:cbv:bizstep:decommissioning. This event timestamps the retirement, identifies the location, and optionally records the disposition (sold, scrapped, recycled, returned).

For privacy-sensitive applications, the kill command can be used to permanently disable the tag, preventing it from responding to any reader. This requires the 32-bit kill password that was set during commissioning. Once killed, the tag cannot be reactivated -- the operation is irreversible.

Privacy and Regulatory Considerations

The GDPR and consumer privacy regulations increasingly require retailers to offer tag deactivation at point of sale. While the untraceable command provides a less destructive alternative (hiding the EPC and reducing range without permanently disabling the tag), some privacy advocates argue that only the kill command provides true assurance that post-sale tracking is impossible. The Digital Product Passport paradigm introduces tension here: the tag needs to remain functional throughout the product's lifecycle for sustainability tracking, even after the initial sale.
