in a case where the relative distance exceeds the limit value, the notification unit transmits the alert at one of a plurality of different levels according to whether or not a person is detected inside a monitoring area near the second device.

2. The information processing system according to claim 1 , further comprising

a monitoring camera that monitors the monitoring area near the second device to detect whether or not there is a person inside the monitoring area.

3. The information processing system according to claim 1 , wherein

in a case where the relative distance exceeds the limit value, the notification unit transmits the alert at one of a plurality of different levels according to whether or not there is a movement or operation of the second device.

4. The information processing system according to claim 1 , further comprising:

a third device that includes a position sensor and a communication unit and is located near the second device,

wherein in a case where the relative distance exceeds the limit value, the notification unit transmits the alert at one of a plurality of different levels according to whether or not there is a movement or operation of the third device.

5. The information processing system according to claim 1 ,

wherein the notification unit is provided at a monitoring server.

6. The information processing system according to claim 1 ,

wherein the notification unit is provided at an image forming apparatus.

7. The information processing system according to claim 1 ,

wherein the first device is a smartphone, and

wherein the second device is a personal computer or a tablet.

8. The information processing system according to claim 7 ,

wherein in a case where the relative distance exceeds the limit value, the notification unit transmits the alert to the smartphone, causes a display of the smartphone to display a message, transmits the alert to the personal computer or tablet, and causes the personal computer or tablet to enter an operation inhibition state.

9. The information processing system according to claim 1 ,

wherein the first device is a smartphone, and

wherein the second device is a bag.

10. The information processing system according to claim 9 ,

wherein in a case where the relative distance exceeds the limit value, the notification unit transmits the alert to the smartphone, causes a display of the smartphone to display a message, transmits the alert to the bag, and causes the bag to output sound.

11. An information processing apparatus comprising:

a processor programmed to:

receive positional information from a first device and a second device each including a position sensor and a communication unit;

calculate a relative distance between the first device and the second device based on the positional information; and

transmit, in a case where the relative distance exceeds a limit value, an alert to at least one of the first device and the second device, wherein

in a case where the relative distance exceeds the limit value, the alert is transmitted at one of a plurality of different levels according to whether or not a person is detected inside a monitoring area near the second device.

12. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

receiving positional information from a first device and a second device;

calculating a relative distance between the first device and the second device based on the positional information;

comparing the relative distance with a limit value; and

transmitting, in a case where the relative distance exceeds the limit value, an alert to at least one of the first device and the second device, wherein

in a case where the relative distance exceeds the limit value, the alert is transmitted at one of a plurality of different levels according to whether or not a person is detected inside a monitoring area near the second device.

13. An information processing system comprising:

a first device that includes a position sensor and a communication unit;

a second device that includes a position sensor and a communication unit; and

a notification unit that transmits, in a case where a relative distance between the first device and the second device calculated based on positional information detected by the position sensors exceeds a limit value, an alert to at least one of the first device and the second device, wherein

in a case where the relative distance exceeds the limit value, the notification unit transmits the alert at one of a plurality of different levels according to whether or not there is a movement or operation of at least one of the second device and a device near the second device.

14. An information processing system comprising:

a first device that includes a position sensor and a communication unit;

a second device that includes a position sensor and a communication unit;

a notification unit that transmits, in a case where a relative distance between the first device and the second device calculated based on positional information detected by the position sensors exceeds a limit value, an alert to at least one of the first device and the second device; and

a third device that includes a position sensor and a communication unit and is located near the second device,

wherein in a case where the relative distance exceeds the limit value, the notification unit transmits the alert at one of a plurality of different levels according to whether or not there is a movement or operation of the third device.
