The most common way to buy a MetroCard is through a vending machine, which you can find at nearly every subway station entrance. Large stations, such as Times Square-42nd St or Grand Central-42nd St, have dozens of machines in various sizes. The larger machines accept cash, credit, and debit cards, while the smaller, "MetroCard Express" machines generally only accept credit or debit cards. 2. Selecting Your Fare Type

It is worth noting that for most travelers, buying a physical MetroCard may no longer be necessary. The OMNY system allows you to simply tap your contactless credit/debit card, smartphone, or wearable device directly at the turnstile or on the bus to pay your fare.
You load a specific dollar amount onto the card. Each subway or local bus ride currently costs $2.90.
