Serial number traceability on Zen 2 turns a recall from a crisis into a routine task.
Across the trade, serial number traceability is the point where good intentions meet operational reality on the Zen 2.

Why serial number traceability matters on the Zen 2
Batch identifiers should appear on the unit, the inner tray and the master carton.
