Suspicious way of working

Can someone explain why it is necessary for a beneficiary of an overseas money transfer to provide their ID, plus a picture of themselves holding their ID? With the rampant identity ***** in South Africa this seems very suspicious. Since the person sending the money has provided the South African Bank account number of the recipient, the money should just be deposited in that Bank Account as requested. We're not talking about tens or hundreds of thousands here - just R1000.
