But I have just received this e-mail:
Dear Travel Smart Rewards user,
Thank you for your support of the Travel Smart Rewards (TSR) thus far.
The Land Transport Authority (LTA) has reviewed the Travel Smart Programme to take into account rail network enhancements in recent years and changes to commuter travel patterns. Following the review, we will be concluding the TSR programme. Please see http://bit.ly/2VWe2rt for more information.
Current TSR users can continue earning points for trips made on the rail network until 31 May 2019. They can convert their points into cash rewards, or use the points to win more points or cash rewards through the game on the TSR portal (The Ride One) until 25 June 2019. Points which are not used by 25 June 2019 will no longer be valid. For further information, please see https://www.travelsmartrewards.lta.gov.sg/faq
Once again, thank you for your support all these years, and we look forward to your active participation in other LTA schemes
Travel Smart Rewards Team--
Long story short, no more. Boo hoo.
