In the 17th Congress, Lacson filed Senate Bill 41, the National Reference Act of 2016, which seeks to establish a National ID system that can help government law enforcers deter criminality and terrorism by facilitating the processes of apprehension and prosecution. The system seeks to address the problems of constant delays and inconveniences in availing of basic public services and social security benefits due to inefficient and unreliable means of identifying the beneficiaries. The bill was signed into law as RA 11055 in late 2018.
