Information processing device, mobile terminal, and information processing method

A mobile terminal that

• receives, by using first wireless communication that is a communication standard capable of performing communication in a wider range than a predetermined short distance, a beacon that is a signal transmitted from an information processing device and is for detecting a mobile terminal within a communication range of the first wireless communication, and
• performs, by using second wireless communication that is a communication standard different from the first wireless communication and is capable of performing communication in a wider range than the predetermined short distance, ranging processing of measuring at least a distance to a payment unit provided with a payment area in which predetermined payment processing is performed, wherein
• in response to detection of entering the payment area on a basis of a result of ranging processing using the second wireless communication, data communication for payment using the second wireless communication is performed with the payment unit.
