On 20 March 2017, LTA started a trial of the usage of contactless debit and credit MasterCard cards for fare payments on all main modes of public transport. Fares are charged directly to their debit or credit cards. From 3 December 2018, the trial was expanded to NETS and Visa cards. On 7 March 2019, the system was renamed to SimplyGo, and it was officially launched on 4 April 2019, starting with MasterCard holders. As of November 2019, Visa and NETS are also able to utilise the system, through usage is encouraged since the COVID-19 social distancing measures, reducing the need to queue at general ticketing machines.
