TransferWise is an online money transfer service that is regulated and fully licensed. It helps people and businesses save significant amounts of money compared to banks by exchanging currencies at the real mid-market rate rather than charging hidden fees of 3-5% like banks. TransferWise provides full transparency on fees and has the lowest real-fee guarantee, being up to 85% cheaper than banks. Money is transferred through matching payments going in different directions within countries so currency never actually changes hands across borders.
