Technical field
The present invention relates to mobile-phone payment, particularly a kind of i Phone with antenna blocks the Kato of the SIM card of scheme entirely.
Background technology
Mobile payment service (Mobile money) will become one of most important development trend coming years, by for the user of global range brings new benefit, and the industries such as telecommunications industry, scientific and technological industry and financial service be brought to profound influence.At present, the scheme that mobile payment technology is existing: the RFSIM scheme of double-interface SIM card scheme (DI-SIM), near-field communication scheme (Near Field Communication is called for short NFC) and 45GHz.
NFC scheme:
NFC combines proposition by manufacturers such as Philip, Nokia, Sonys.It in conjunction with radio-frequency card reader, non-contact card and point-to-point function, is a kind of short-distance wireless communication technology on one chip.NFC adopts 13.56MHz as communication frequency standard, the radio frequency standard such as compatible ISO14443, ISO15693, and 10 centimetres of left and right of operating distance, data transmission bauds can be selected 106Kb/s, 212Kb/s or 424Kb/s.NFC chip is contained on reader antenna shell, and mobile phone just can be realized the information of paying by mails and reading other NFC equipment or label.NFC chip is connected by SWP agreement with SIM chip.SWP(C6) on a holding wire, based on voltage and load-modulate principle, realize full duplex communication, can realize SIM card and under ISO7816 interface definition, support 7816 and two interfaces of SWP simultaneously, and reserve the pin (C4, C8) of expansion the 3rd high speed (USB) interface.SWP has systematically defined the multi-layer protocol from physical layer, link layer to application layer, and has become etsi standard.
NFC mobile phone has three kinds of mode of operations:
Contactless card simulation model: NFC mobile phone can be modeled to a contactless card by read/write, passive response in the radiofrequency field that it only sends at other equipment.
Ad hoc mode: NFC mobile phone all initiatively sends radiofrequency field with other equipment both sides and sets up point-to-point communication.
Reader/writer mode: NFC mobile phone, as a read write line, initiatively sends the radiofrequency field of oneself and removes identification and other NFC equipment of read/write.
Double-interface SIM card:
Double-interface SIM card is in traditional SIM card, to add Non-contact radio-frequency interface, the antenna that Energy Coupling and transfer of data are provided is integrated on mobile phone or flexible PCB, by contact interface processing tradition GSM order, adopt contactless interface that the value-added services such as E-Payment are provided.
Current main flow double-interface SIM card mobile payment solution can realize various noncontacts and move application, such as noncontact mobile payment, stored value card, PBOC debit/credit and other various non-telecommunications application.Array structure from product structure has:
One) SIM antenna and circuit are all integrated in SIM card;
Two) circuit is integrated in SIM card, antenna is drawn and is placed on mobile phone or the battery of mobile phone back side;
Three) circuit and antenna be all outside SIM card, such as the I-SIM scheme of Motorola, and SIMpass scheme.
Such scheme is all to adopt passive load-modulated to make mobile phone to read write line transmission of signal, also the load-modulated of having chance with that has recently SIM card initiatively to launch, make antenna in SIM card just can and read write line between communication, be referred to as SIM card and entirely block scheme NFC.But because the supply current of SIM card is limited, and the shielding to the signal of antenna transmission of the SIM card of different mobile phones is different, makes mobile phone adaptability not high, mainly adapts to SIM card at the mobile phone of battery outside.
