## Abstract

A communication apparatus includes first communication means having a first communication function for wirelessly communicating with a partner apparatus, and second communication means having an electric power supply function for wirelessly supplying electric power to the partner apparatus and a second communication function for wirelessly communicating with the partner apparatus. The second communication function is for transmitting specific data sequence to the partner apparatus in response to reception of specific data from the partner apparatus, and the electric power supply function is for supplying electric power to the partner apparatus in a case of receiving from the partner apparatus, with the first communication means, a signal indicating that the partner apparatus has received the data sequence.

## Claims

### Claim 1

A communication apparatus comprising:
a power transmission unit configured to perform wireless power transfer;
a first communication unit configured to communicate random information with another communication apparatus via a first communication method; and
a second communication unit configured to communicate information with said another communication apparatus via a second communication method,
wherein the power transmission unit performs the wireless power transfer to said another communication apparatus after it is confirmed whether the random information communicated by the first communication unit is the same as the information communicated by the second communication unit.

### Claim 2 (depends on 1)

The communication apparatus according to claim 1, wherein the second communication unit transmits the information multiple times.

### Claim 3 (depends on 1)

The communication apparatus according to claim 1, wherein the second communication unit transmits the random information.

### Claim 4 (depends on 1)

The communication apparatus according to claim 1, wherein the first communication unit receives the random information from said another communication apparatus.

### Claim 5

A control method for a communication apparatus, the control method comprising:
communicating random information with another communication apparatus via a first communication method;
communicating information with said another communication apparatus via a second communication method; and
performing a wireless power transfer to said another communication apparatus after it is confirmed whether the random information communicated via the first communication method is the same as the information communicated via the second communication method.

### Claim 6

A non-transitory computer-readable storage medium that stores a computer program for causing a computer to execute a control method for a communication apparatus, the control method comprising:
communicating random information with another communication apparatus via a first communication method;
communicating information with said another communication apparatus via a second communication method; and
performing a wireless power transfer to said another communication apparatus after it is confirmed whether the random information communicated via the first communication method is the same as the information communicated via the second communication method.
