Mobile communication terminal having a function of reading out information from contactless type communication tag and method for providing information of whether an article is genuine or not

摘要

A mobile communication terminal that receives information received from a contactless communication tag is disclosed. The mobile communication terminal comprises first and second communication units, a storing unit, a decryption unit, an information reading unit and an output unit. The first communication unit wirelessly exchanges data with the contactless communication tag and wirelessly sends power required for the contactless communication tag. The second communication unit transmits data to and receives data from a service management server via a wireless communication network. At least one encryption key related information is stored on the storing unit. The decryption unit decrypts data received from the contactless communication tag based on encryption key related information that is selected from the encryption key related information by encryption key specifying information received from the contactless communication tag. The information reading unit requests product information to the contactless communication tag attached to a product and reads the product information received from the contactless communication tag. The output unit outputs the read product information.
