# Introduction
Product authentication your customers check with a tap.
Counterfeiters copy labels. Photograph a printed code, a QR, or a serial number
once, and the same code goes on every fake.
TAGBASE moves the proof off the label and into the product. Each item carries a
small **dynamic NFC tag** that builds new proof every time somebody taps it. A
customer taps the product with a phone, taps once more to confirm, and the page
says whether the product is real. There is no app to install and no account to
create.
The second tap is what catches copies. A genuine tag answers differently the
second time, and a copy can only repeat itself.
