Payment is the most important thing that differentiates an online store from a physical one. While shopping on an eCommerce store, you get the privilege of buying products using electrical payment options. So, you often need digital currencies that lets you pay for the things you want to buy.
In case of WooCommerce stores or multivendor shops, customers might feel the necessity of having their own wallets where they can store some money and use them when required. This is what we call a digital wallet. To make shopping even more interesting, store owners tend to provide cash back offers.
