A counterfeit pharmaceutical product identification system and method for determining authenticity of pharmaceutical products using NFC (Near Field Communication) enabled mobile device is disclosed. A unique secure code, invisible to human eyes, is embedded inside the packaging of the pharmaceutical products. An authentication server stores a database of pharmaceutical products and the unique secure codes associated with each of the pharmaceutical products. At least one mobile device, connected to the server, is configured to read unique secure code embedded inside the packaging of the pharmaceutical product, by bringing the mobile device in close proximity to the packaging. The mobile device authenticates the pharmaceutical product by communicating with the authentication server and comparing the unique secure code attached to the pharmaceutical product with the secure code saved in the database whereby identifying the genuine pharmaceutical product instantly.
