Authenticity checks protect distributors and retailers from grey market Nex 4 stock.
Distributors reviewing their Nex 4 range usually find that authenticity checks explains most of the variance in results between accounts.
Shops that receive a short briefing on authenticity checks convert noticeably better than shops that only receive stock.
Why authenticity checks matters on the Nex 4
A scratch code or QR verification on every unit is now the minimum expectation.
Documentation is not paperwork for its own sake; on authenticity checks it is the difference between a clean clearance and a delayed one.
Batch numbers should match between inner tray, carton and invoice.
