One-tap ordering is an interesting concept when it comes to conducting business online, especially where the food delivery service is concerned. Rather than having customers go through a checkout process and entering their card details to pay, a one-tap solution allows them to add items to their cart and pay with a single tap. Domino’s Pizza has integrated this type of solution in their wearable application. Such a feature could be useful to Bitcoin users as well.
