# Overview

> Payment cards drive revenue through interchange and make your product an everyday financial tool. This section covers everything from designing a card program to issuing and managing cards through their whole life.

Cards increase stickiness in a way few other features do. They give your customers fast, convenient access to their funds, they generate interchange revenue on every purchase, and they put your brand in front of your customer several times a day.

The Synctera Cards API issues and manages cards for your customers over the entire life of a card - from issuing a card, through activation and day-to-day management, to reissuance and termination. However, before you start issuing a card, you need to define your card program based on your business goals.

This guide explains how to set up a card program and how to use the Cards API to issue and manage cards throughout their lifecycle.
