Which ID card is NOT valid for a customer to be entitled to half fare?

A Medicaid Card is not typically recognized as valid for a customer to qualify for half fare on transport services. Half fare programs usually require identification that explicitly indicates a person's eligibility based on age, student status, or specific government assistance programs that relate to transportation. While a Medicaid Card does indicate that an individual is enrolled in a certain health program, it does not provide a direct link to transportation fare discounts.

In contrast, a Driver's License, Government Issued ID, and Student ID are all considered valid forms of identification that can demonstrate eligibility for half fare. A Driver's License can prove age or identity, a Government Issued ID often indicates status related to veterans or senior citizens, and a Student ID clearly indicates a person's enrollment in an educational institution, which is a common criterion for reduced fare eligibility.
