Send money is the everyday name, and usually the button label, for a consumer payment service that transfers funds from one person to another. In banking apps and wallets it refers to a domestic P2P payment. In the remittance industry it means an international money transfer, and operators describe the originating side of their business as the send side.
The steps are similar in each case. The sender chooses a recipient, enters an amount and sees the fee and, for cross-border transfers, the exchange rate and the amount to be received. The sender funds the transfer from a balance, bank account, card or cash at an agent. The provider then screens the transaction and delivers the money by account credit, wallet credit or cash pickup. A business offering this service to the public normally needs a money transfer license or must act as the agent of a licensed firm.
