Anti-Counterfeiting Solutions for the Wine & Spirits Industry
16 October 2025, by Synexa
The Challenge
In the profitable industry of wine and spirits, counterfeiters attempt to make money by copying or refilling original bottles with inferior liquids. This can lead to lost sales for your company, as well as potential damage to your brand's reputation and the health of your customers. However, it is possible to prevent counterfeiting while also enhancing the customer experience without compromising your intricate packaging design.
Our Solution
When a consumer taps their NFC-enabled smartphone to the product, the NTAG does not simply transmit a static URL. Instead, it dynamically generates a randomly unique URL for each interaction. This URL is a complex string that includes:
The NTAG's unique UID.
The current scan counter value (proving it's a live, active tag).
The product's status (e.g., whether it's been opened, as we'll discuss below).
Crucially, a CMAC (Cipher-based Message Authentication Code). This CMAC is a cryptographic signature generated by the NTAG using its secret AES-128 key and the current data set (UID, counter, status). It essentially proves the tag is genuine and the data hasn't been tampered with in transit.
