"Friends who take the T. They've started switching to their new payment system which eliminates cash payments on board, but will allow you to pay with a smartphone, fare media card, or contactless credit card. You'll still be able to pay cash at fare vending machines to buy the fare media cards before boarding.
"They have announced their plan to charge a $5 mandatory overdraft protection fee for each kind of payment (each new fare card, smartphone app, credit card).
"Would you please take this two-question survey to share your opinion about the required $5 fee. Feel free to share it with anyone who takes the T. I'm happy to answer any questions."
