Today, we can tag at the pallet level and associate cases with pallet labels, drastically reducing tag costs, infrastructure and capital expenditures. If you have a distributed low-volume operation—or can't afford an automated data-collection system or support significant process change—you can track pallets using handheld RFID interrogators. The next level up is to RFID-enable warehouse dock doors to automate data collection at specific choke points. That allows you to track pallets as they go in and out of your warehouse.
