High speed identification of stacked items with PJM StackTag

One of the key advantages of SATO’s PJM RFID systems is the ability to identify tags on items when multiple items are stacked, or closely located, even in the presence of liquids. This stacking feature is provided by PJM StackTag™. We provide a number of tag formats and tag sizes to suit different applications.

A number of popular tag types are available from SATO VICINITY. Depending on volumes, new tags can be designed for particular applications. Typically, tags are provided as bare inlets, transparent adhesive labels or paper adhesive labels.
