The circuit board, the intelligent card unit and the NFC module are integrally packaged through rubber having ferrite. The antenna coil is disposed on the ferrite rubber layer. The NFC device and the wireless payment device are advantageous in that the problem of the conventional NFC device that the antenna coil has large interference from the external or from the NFC device when the antenna coil is designed to the small can be resolved.
Description
Technical field
The utility model belongs to data communication technology field, relates in particular to a kind of NFC device and wireless payment device.
Background technology
Close range wireless communication (Near Field Communication, NFC) is a kind of non-contact automatic identification technology.NFC becomes the mainstream technology of mobile non-contact application gradually at present, especially shows wireless payment technical field.In prior art, generally attaching antenna coil on printed circuit board (PCB), the requirement receiving in order to reach aerial coil signal, area and the volume requirement of described aerial coil are larger, therefore the NFC device of described aerial coil or the area of associated components and volume are installed also relatively large, cannot meet the demand of Mobile payment terminal miniaturization.But if aerial coil design is less, the external world or NFC device itself is larger to aerial coil interference so, easily cause swiping the card or occur the problem of jitter when Card Reader.
Utility model content
The utility model embodiment provides a kind of NFC device, and to solve existing NFC device in aerial coil design hour, the external world or NFC device itself is to the larger problem of aerial coil interference.
The utility model embodiment realizes like this, a kind of NFC device, comprise aerial coil, NFC module and be arranged on the intelligent card unit on circuit board, described circuit board, intelligent card unit and NFC module are by comprising ferritic glue integrative packaging, and described aerial coil is arranged on ferrite glue-line.
Further, one deck ink or ferrite glue-line are set on described aerial coil.
Further, described NFC device also comprises magnetic core, and described magnetic core is placed on described ferrite glue-line.
Further, described NFC device also comprises magnetic core, and described magnetic core is flat shape, and described magnetic core is placed in described ferrite glue-line.
Further, described in, comprising ferritic glue is epoxy resin.
Further, described NFC device is SD card, MicroSD card, miniSD card, SDHC card or SIM card.
The object of the utility model embodiment is also to provide a kind of wireless payment device, and described wireless payment device comprises above-mentioned NFC device.
The beneficial effect that the utility model embodiment compared with prior art exists is: the utility model embodiment arranges ferrite glue-line between aerial coil and circuit board, intelligent card unit, NFC module, can effectively prevent that by ferrite glue-line the external world and circuit board, intelligent card unit and/or NFC module, battery from disturbing the signal of aerial coil, effectively solve existing NFC device in aerial coil design hour, the external world and NFC device itself is to the larger problem of aerial coil interference.And due to the module-integrated encapsulation of described circuit board, intelligent card unit and NFC, aerial coil designs again less, thereby can effectively meet the demand of Mobile payment terminal miniaturization.
Brief description of the drawings
