Shopping check-out with a payment card
A technique for providing a checkout experience using a payment card is disclosed. An electronic device at a store detects a movement of a product away from the store by using a first short-range wireless link. The electronic device then receives from the product information identifying the product. The electronic device also detects the presence of a payment card near the product around the same time that it detects the movement of the product, by using a second short-range wireless link. The electronic device then receives information from the payment card information identifying an account on a server system. Upon determining that the product is at least a certain distance away from the store for at least a certain amount of time, the electronic device processes a payment for the product by the owner of the account.
1. A method performed by an electronic sensing device, the method comprising:
detecting, by the electronic sensing device, in a store, a movement of a product away from the store, by using a first short-range wireless path;
detecting, by the electronic sensing device, a presence of a payment card within a first specified distance of the product and within a first specified amount of time of detecting the movement of the product, by using a second short-range wireless path;
sending, by the electronic sensing device, to the payment card, a request to transmit information identifying the product;
receiving, by the electronic sensing device, from the payment card, the information identifying the product and first information identifying an account on a server system,
wherein the server system offers a payment service and manages accounts that are each associated with a funding source;
detecting, by the electronic sensing device, a presence of a mobile device within the first specified amount of time of detecting the movement of the product, by using a third short-range wireless path;
receiving, by the electronic sensing device, from the mobile device, second information identifying an account on the server system;
determining, by the electronic sensing device, whether the product is at least a second specified distance away from the store for more than a second specified amount of time;
determining, by the electronic sensing device, whether the first information and the second information match; and
in response to a first determination result indicating that the product is at least the second specified distance away from the store for more than the second specified amount of time and a second determination result indicating that the first information and the second information match,
obtaining, by the electronic sensing device, information regarding the product, including a price, based on the information identifying the product;
sending, by the electronic sensing device, the first information, the information identifying the product, and the price to the server system; and
receiving, by the electronic sensing device, a response from the server system confirming that the product is purchased using the account,
wherein the mobile device includes a Radio-Frequency Identification (RFID) scanner, a Bluetooth Low Energy (BLE) scanner, or a Near Field Communication (NFC) scanner, and
wherein the first, second, or third short-range wireless path is implemented using Radio-Frequency Identification (RFID), Near Field Communication (NFC), Wi-Fi, Bluetooth, or Bluetooth Low Energy (BLE).
2. The method of claim 1 , further comprising keeping track of a location of the product using the first short-range wireless path.
3. The method of claim 1 , further comprising:
receiving, by the electronic sensing device, from the server system, information regarding the account, wherein the information regarding the account comprises information of an associated funding source; and
requesting, by the electronic sensing device, an authorization of a payment of the price from the associated funding source.
4. The method of claim 1 , wherein the mobile device is a phone, a camera, a watch, eyewear, a tablet computer, a laptop computer, or a personal digital assistant.
