Can cash balances from two cards be combined onto one card?
If you have more than one SUBWAY® Card with cash loaded on them, you can merge the balances from one Card to the other, provided that all cards have been registered under the same profile at www.mysubwaycard.com, and provided you are merging two or more of the same card type (example: Cash Card to Cash Card, not Cash Card to Rewards Card or vice versa).
