                            Use cases of the SPSN for IoT applications and services

                          (This appendix does not form an integral part of this Recommendation.)


            This appendix describes typical SPSN scenarios for IoT applications and services.

            I.1     SPSN for commercial merchant service

            In this scenario, an SPSN can be used to manage supplier service information. In commercial service,
            suppliers  need  to  collect  information  about  products,  order  data  and  the  purchasers'  account
            information  required  to  complete  transactions.  On  one hand,  an  SPSN  has  sensors  for  gathering
            information including identity data, transaction sensitive data and geographical position data that is
            acquired through various technologies, such as NFC, sounder and Bluetooth. On the other hand, an
            SPSN has a big screen to display real information for both suppliers and purchasers. Therefore, it is
            natural that suppliers use SPSNs to gather information. See Figure I.1.
            Suppliers  or  retailers  can  use  SPSNs  to  access  and  control  each  IoT  device  using  related  IoT
            applications installed on them. The SPSN performs identity recognition and information acquisition
            during the transaction process.
            Subsequently, information is transferred to a data processing centre, through a special network, such
            as the Internet, cable network or wireless network.
            Finally, information processing centres deployed in banks and third parties undertake information
            analysis,  decision-making,  sharing,  publishing  and  provision  to  users  of  an  instant  intelligence
            acquisition service.


            For instance, when a customer wants to buy products and pay for them, the merchant could use the
            SPSN to scan tags to collect the products' information, swipe the contactless bank card to get the
            account information or even swipe the customer's mobile phone if he or she has a mobile wallet. As
            a result, the SPSN collects all the data together just as the sink node does. It sends the data to  a
            processing centre through the network and also transmits feedback to the merchant and customers.
