Bill Splitting

When a merchant sells goods or services in a sales transaction, a merchant device can generate a bill. The bill includes an itemized list of the goods and services, a price for each item, and an identifier of the sales transaction. A first customer and a second customer split the bill using a first customer device and a second customer device, respectively. The first customer device establishes communication between the first customer device and the merchant device. Using the identifier of the sales transaction, the first customer device pays a portion of the itemized list of the goods and services at the merchant device. The second customer device establishes communication between the second customer device and the merchant device. Using the identifier, the second customer device pays a remaining portion of the itemized list of the goods and services at the merchant device.
