After more than two decades, Metrocards will be a blast from the past and is getting ready to swipe left on MetroCards. For more than 20 years, the MTA has used the MetroCard but has decided it may be time for an upgrade. The MTA approved more than $500 million to bring in the next fare-payment system beginning late 2018. By 2020, all subways and buses will adopt the more modern payment system. Officials say the plan is to fully retire the MetroCard by 2023. Until then, riders will still be able to use it.
