Subway cards are reloadable and can be used to store money. However, they cannot be redeemed for cash, and $500.00 is the maximum that can be on a Subway card at any time. $2000.00 is the maximum that can be associated with the card every month.
Subway card reloading is done online by visiting the website on the back of the card, or by going to a participating restaurant. There is also a Subway app that allows customers to reload their accounts by using a credit card. A staff member at participating Subway locations can check the balance of a Subway card. Balances are also available through the website on the back of the card or by calling the number.
