METHOD AND SYSTEM FOR TRANSMITTING INTERRUPTED TRANSACTIONS
A payment module with one or more processors, memory, and a first communication capability is coupled with a payment accepting unit (e.g., an automatic retailing machine for dispensing goods and/or services). The payment module obtains a notification indicating completion of a transaction, and an amount thereof, performed by user of a device at the payment accepting unit. In response to receiving the notification, the payment module generates and stores transaction information based on the notification; and sends the transaction information to the device via the first communication capability (e.g., BLE). After sending the transaction information to the device, the payment module: deletes the stored transaction information if acknowledgement information is received from the device within a predetermined time period; and maintains the stored transaction information if the acknowledgement information is not received from the device within the predetermined time period.
1 . A method of payment processing acknowledgment, comprising:
at a payment module coupled with a payment accepting unit, the payment module including one or more processors, memory, and one or more first communication capabilities:
obtaining, from the payment accepting unit, a first notification indicating completion of a first transaction performed by a first user of a first device at the payment accepting unit and an amount of the first transaction;
in response to receiving the notification:
generating first transaction information based at least in part on the first notification;
storing the generated first transaction information; and
sending the generated first transaction information to the first device via one of the one or more first communication capabilities; and
after sending the first transaction information to the first device:
in accordance with a determination that first acknowledgement information is received from the first device within a predetermined time period, deleting the stored first transaction information generated for the first transaction performed by the first user of the first device; and
in accordance with a determination that the first acknowledgement information is not received from the first device within the predetermined time period, maintaining the stored first transaction information generated for the first transaction performed by the first user of the first device.
2 . The method of claim 1 , further comprising:
in accordance with the determination that the first acknowledgement information is not received from the first device within a predetermined time period, disabling usage rights for the first user at the payment accepting unit.
3 . The method of claim 1 , further comprising:
in accordance with the determination that the first acknowledgement information is not received from the first device within the predetermined time period, broadcasting an information packet via one of the one or more first communication capabilities, wherein the information packet includes one or more status flags indicating one or more unacknowledged first transactions including the first transaction performed by the first user of the first device.
4 . The method of claim 1 , further comprising:
after determining that the first acknowledgement information is not received from the first device within the predetermined time period:
obtaining, from the payment accepting unit, a second notification indicating completion of a second first transaction performed by a second user of a second device at the payment accepting unit and an amount of the first transaction; and
in response to receiving the second notification:
generating second transaction information based at least in part on the second notification;
storing the generated second transaction information; and
sending the generated first transaction information and the generated second transaction information to the second device via one of the one or more first communication capabilities.
5 . The method of claim 4 , further comprising:
in accordance with a determination that second acknowledgement information is received from the second device within the predetermined time period, deleting the stored first transaction information generated for the first transaction performed by the first user of the first device and the stored second transaction information generated for the second transaction performed by the second user of the second device; and
in accordance with a determination that the second acknowledgement information is not received from the second device within a predetermined time period, maintaining the stored first transaction information generated for the first transaction performed by the first user of the first device and the stored second transaction information generated for the second transaction performed by the second user of the second device.

obtaining, from the payment accepting unit, a first notification indicating completion of a first transaction performed by a first user of a first device at the payment accepting unit and an amount of the first transaction;
in response to receiving the notification:
generating first transaction information based at least in part on the first notification;
storing the generated first transaction information; and
sending the generated first transaction information to the first device via one of the one or more first communication capabilities; and
after sending the first transaction information to the first device:
in accordance with a determination that first acknowledgement information is received from the first device within a predetermined time period, deleting the stored first transaction information generated for the first transaction performed by the first user of the first device; and
in accordance with a determination that the first acknowledgement information is not received from the first device within the predetermined time period, maintaining the stored first transaction information generated for the first transaction performed by the first user of the first device.
8 . The payment module of claim 7 , wherein the one or more programs further comprise instructions for:
in accordance with the determination that the first acknowledgement information is not received from the first device within a predetermined time period, disabling usage rights for the first user at the payment accepting unit.
