The Zap PoS app and hardware take an everyday merchant and turn them into a full-fledged, independent Bitcoin (and Lightning) merchant. Point-of-Sale applications are powered by a hardware device running bitcoin core, lightning and the BTCpay server. This allows the owner to fully control his keys without third party. The Lightning network has already been touted as a technology that can completely transform the industry, with a way around the scaling problem associated with Bitcoin. Many companies have realized the benefits of the network and have tried to take advantage of it themselves. The benefits are clear. There is no more powerful position to occupy than an independent merchant. No one can refuse you payment, no refund, no downtime, no banking problems, no border restrictions, attract new customers, etc.
