The currency of Swaziland, the lilangeni plural: "emalangeni", is tied to the South African rand at 1:1. Shops in Swaziland often accept and make change for both currencies indiscriminately. This is not the case in South Africa, however, so if you are planning to visit South Africa also, you may prefer to request rand in exchange for emalangeni at banks in Mbabane or Manzini: proof of identity is required. It is impossible to exchange your emalangeni at Johannesburg Airport, as well as in the UK. All Swazi vendors will take Rand, but no South African vendors will take emalangeni.
Note that when traveling on the kombis in Swaziland, the operators will NOT take Rand coins.
