TECHNICAL FIELD 
       [0001]    The disclosure relates to the field of mobile payment, and in particular to a stylus, a mobile terminal and an information processing method. 
       BACKGROUND 
       [0002]    Compared with a conventional close communication technology, a Near Field Communication (NFC) technology not only can rapidly establish a data connection, but also has higher data transmission security. Along with the maturation of the NFC technology, the NFC technology is gradually applied to the field of mobile payment. 
         [0003]    However, a conventional merchant terminal adopted by a merchant usually does not support payment using the NFC technology, and needs to be replaced by a merchant terminal supporting payment using the NFC technology if the NFC technology is needed for payment. The replacement cost is very high.
