Facebook, which owns WhatsApp, has launched a payments service on the platform.
People can send money and make purchases within the WhatsApp app.
This is the first country where the service will be fully rolled out.
It has been testing payments in India for a couple of years.
What does this mean?
Facebook says it wants to make payments “as easy as sharing photos” – users will be able to send money to their WhatsApp contacts and authorise it using a PIN or biometrics. At the moment people will be able to link various Visa and Mastercard debit cards to their WhatsApp account.
