At this time, the transfer of the certificate may be in the form of NFC type or non-NFC type smartphone to NFC type or non-NFC type smartphone, website to NFC type or non-NFC type smartphone, , The method of transferring the purchased certificate can be performed as follows.

First, when the buyer transfers the room after purchasing it, the transfer is not confirmed at the time of purchase.

For example, this method transmits a parent certificate received when a purchaser purchases a room through a room purchasing application to the server 40, verifies and requests a child certificate, and the server 40 ) To send a sub-certificate to the user's room purchase app using the guest room. This method has two certificates, only lower certificates are available.

Second, the transfer is concurrent with the purchase of the room, and the transfer is confirmed at the time of purchase.

For example, the method may be configured to transfer an NFC certificate from a purchaser's room purchase app to a room purchaser's smartphone's room purchase app at the time of purchase of the room. In this method, only one certificate exists, and the user's adult authentication is required.

Third, when purchasing a room through a web site, the NFC certificate is directly transferred to the room purchasing app of the guest user's smartphone. In this method, there is only one certificate, the buyer can send it to the user or the buyer can send it to the user, and the user's adult authentication is required.

Fourth, when purchasing a guest room through a web site, the server 40 transmits an authentication number having the same effect as the certificate to the smartphone of the user as a text message, and confirms the confirmation number at the front desk of the hotel using the authentication number A card key for access is issued, or a room is used by inputting an authentication number through a button of a smart door lock of the guest room. This method is applicable only when the user is not a smartphone user, and an adult authentication tool is needed because the user can not confirm the entrance and use of the room of the minor.
