Processing interrupted transaction over non-persistent network connections
An offline retail machine comprising a short-range transceiver, one or more processors, and memory performs communications operations via one or more mobile devices. The communications operations include establishing via the short-range transceiver a connection with a first mobile device, and transmitting first information to the first mobile device. Upon not receiving an acknowledgement that the first information was received by a remote server, the offline retail machine maintains the first information in the memory and establishes, via the short-range transceiver, a connection with a second mobile device, appends the first information to second information, and transmits the first and second information to the second mobile device. Upon receiving acknowledgement that the first and second information were received by a remote server, the offline retail machine deletes the first and second information.

in accordance with the determination that the first acknowledgement information is not received from the first mobile device within the predetermined time period:
disabling usage rights of the first user who is associated with the first mobile device at the offline retail machine; and
maintaining as enabled usage rights of other users, distinct from the first user, at the offline retail machine.
5. The offline retail machine of claim 1 , wherein the communications operations further comprise:
in accordance with a determination that the first acknowledgement information is received from the first mobile device within the predetermined time period, deleting the first information from the memory.
6. A method of performing communications operations via one or more mobile devices, the method comprising:
at an offline retail machine comprising a short-range transceiver, one or more processors, and memory:
establishing via the short-range transceiver a connection between the offline retail machine and a first mobile device proximate to the offline retail machine;
transmitting via the short-range transceiver to the first mobile device first information including a record of one or more products and/or services provided by the offline retail machine for a first user who is associated with the first mobile device;
determining whether first acknowledgement information is received from the first mobile device within a predetermined time period, the first acknowledgement information acknowledging that a remote server received the first information;
in accordance with a determination that the first acknowledgement information is not received from the first mobile device within the predetermined time period:
maintaining the first information in the memory; and
broadcasting an information packet via the short-range transceiver, wherein the information packet includes a status flag indicating unacknowledged information including the first information.
7. The method of claim 6 , further comprising:
in accordance with the determination that the first acknowledgement information is not received from the first mobile device within the predetermined time period:
establishing via the short-range transceiver a connection between the offline retail machine and a second mobile device proximate to the offline retail machine;
transmitting via the short-range transceiver to the second mobile device second information and the first information, wherein the second information includes a record of one or more products and/or services provided by the offline retail machine for a second user who is associated with the second mobile device;
determining whether second acknowledgement information is received from the second mobile device within the predetermined time period, the second acknowledgement information acknowledging that a remote server received the first and second information; and
in accordance with a determination that the second acknowledgment information is received from the second mobile device within the predetermined time period, deleting the first and second information from the memory.
8. The method of claim 7 , further comprising:
in accordance with a determination that the second acknowledgement information is not received from the second mobile device within the predetermined time period, maintaining the first and second information in the memory.
9. The method of claim 6 , further comprising:
in accordance with the determination that the first acknowledgement information is not received from the first mobile device within the predetermined time period:
disabling usage rights of the first user who is associated with the first mobile device at the offline retail machine; and
maintaining as enabled usage rights of other users, distinct from the first user, at the offline retail machine.
10. The method of claim 6 , further comprising:
in accordance with a determination that the first acknowledgement information is received from the first mobile device within the predetermined time period, deleting the first information from the memory.
11. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by one or more processors of an offline retail machine having a short-range transceiver, cause the offline retail machine to perform communications operations via one or more mobile devices, the communications operations comprising:
establishing via the short-range transceiver a connection between the offline retail machine and a first mobile device proximate to the offline retail machine;
transmitting via the short-range transceiver to the first mobile device first information including a record of one or more products and/or services provided by the offline retail machine for a first user who is associated with the first mobile device;
determining whether first acknowledgement information is received from the first mobile device within a predetermined time period, the first acknowledgement information acknowledging that a remote server received the first information;
in accordance with a determination that the first acknowledgement information is not received from the first mobile device within the predetermined time period:
maintaining the first information in the memory; and
