This document discusses the use of tax stamps and authentication technologies in India to increase liquor tax revenue and curb illegal liquor. It provides an overview of the Authentication Solution Providers' Association and how they have worked with state governments to implement hologram-based tax stamps. Implementation of these stamps has led to significant increases in tax revenue for states like Tamil Nadu, Madhya Pradesh, and Uttar Pradesh. The document advocates for expanding the use of track-and-trace technologies in tax stamps to all states by 2016 to further reduce illicit liquor and protect public health while growing government funds.
