Claim 10:
11. An information processing system including a communication apparatus and an information processing apparatus, the communication apparatus including a first communication unit that performs communication via a predetermined wireless communication, the information processing apparatus including a second communication unit that performs communication via the predetermined wireless communication, the information processing system comprising:
in the communication apparatus which includes a memory storing instructions and at least one processor that executes the stored instructions and configures the communication apparatus to,
write, in response to a first user operation, key information used to generate a decryption key and first information having a predefined structure that is encrypted by using an encryption key corresponding with a decryption key generated from the key information, into a storage area of the communication apparatus that is accessible by the information processing apparatus, the key information and the first information stored in the storage area being readable by the second communication unit of the information processing apparatus;
in the information processing apparatus including a memory storing instructions and at least one processor that executes the stored instructions and configures the communication apparatus to,
read, in response to receipt of a second user operation, by the second communication unit, the key information and the first information that have been written into the storage area of the communication apparatus by the writing unit of the communication apparatus;
decrypt the first information by using the generated decryption key;
determine whether the decrypted first information corresponds with predetermined second information stored in the information processing apparatus;
perform a registration process for registering the communication apparatus with an application executing on the information processing apparatus when it is determined by the information processing apparatus that the decryption key is generated from the key information, that the first information is decrypted by using the generated decryption key, and that the decrypted first information corresponds with the predetermined second information, and
not perform, by the information processing apparatus, the registration process when it is determined by the information processing apparatus that the decrypted first information does not correspond with the predetermined second information,, wherein the predetermined second information has been stored in advance of the registration process and without communicating with the communication apparatus.
