# How it works

Fonbnk Pay Widget is a secure and efficient way to accept payments in stable coins from customers in an integrated and non-integrated way.

It's a P2P platform that connects people who want to sell mobile money (Airtime, Mobile Money, Bank, etc.) with people who would like to buy it.

How it works for end users:

1. A customer selects his funds source (Airtime, Mobile Money, Bank, etc.) and the amount of crypto he would like to receive
2. Customer provides his wallet details
3. Customer transfers funds to an agent we found for him and confirms the order
4. An agent confirms the order and the system sends crypto to a customer's wallet

Note over User: Send funds to an agent
User->>Widget: Confirm that funds are sent
Note over Agent: Check if funds are received
Agent->>Widget: Confirm that funds are received
Widget->>User: Send crypto to user wallet" %}

Example of a flow:

Pay Widget supports configuration via [URL parameters](/v1.5/on-ramp/url-parameters.md). Merchants can force the widget to use specific wallet address, memo, crypto amount, etc. This allows integrating the widget as a payment system.<br>
