Abstract
A case for an electronic device is provided. The case includes a battery, an interface to receive electrical power from an external power source, a payment device reader, a product information input device, and a computer processor configured to execute computer-readable instructions. The computer processor executes the instructions to conduct communications with the electronic device, limit an amount of current of the received electrical power consumed by the case, allocate the amount of current among the battery and the electronic device based on the communications, read product information from a product using the product information input device, and read a payment device using the payment device reader, where the payment device is used to pay for the product.
