Yes, a Rabbit Card—the primary stored-value card for Bangkok's BTS Skytrain—costs money to purchase and maintain. As of 2026, a new Rabbit Card typically costs 200 THB (approx. $6). This price includes a non-refundable 100 THB issuance fee and an initial 100 THB of stored value that you can use for fares or at participating retail partners like McDonald's or Starbucks. Unlike many other global transit cards, the deposit is generally not refundable. To get one, you must present your physical passport at any BTS ticket office for registration, which is a mandatory security requirement in Thailand. For 2026 travelers, it is a peer-to-peer recommendation to only top up what you need; while the card itself is valid for seven years, any stored value on the card typically expires if not used within two years of your last transaction, making it less ideal for very infrequent visitors to Thailand.
