# Card Commerce Protocol

Card Commerce allows merchants to keep stock-keeping units (SKUs): Which products are you selling? How many of those do you have in your inventory? What is the price? Are they priced in stablecoins, USD, or your own community token? What types of discounts do you give to people based on their affiliation / membership / payment method etc.? And with this commerce capability comes the storefront.
