CheckNote is the most secure verification system of goods extending CheckOpti options with the use of a banknote

The system is meant for protection of premium products – depending on the price of goods a banknote of a particular value is packaged with the item. The serial number of the banknote is the verification code of the product.

To check the validity of an item either numeric code is entered on the ChecktoCashup® website or square code is scanned with ChecktoCashup® Authenticity App.

The system will respond with attached banknote serial number. Absence of a banknote or mismatch of the serial number means that the item is counterfeit.
