Applying for reduced fares for senior citizens on the Singapore MRT

Problem
How do you find out if you are eligible for reduced fares for senior citizens in Singapore?

Answer
Find out which of the stations have the application forms. Only the larger stations do so. You will be given the forms which tell you how to apply on line. You need a photo and a Singapore citizen or permanent resident number.

When you log in and fill in the details, and upload the photo, you are told whether your application has been accepted and how long you must wait.

A couple I know in Singapore just applied on line. They were told on line that their application was being processed. Delivery of the card would take eight weeks. In theory you can apply from a computer outside Singapore. It might be a good idea to try to apply eight weeks before you need it.
