Description
Technical field
The present invention relates to a kind of mobile phone and magnetic bar code recognition of tool magnetic testing function, particularly relate to and a kind ofly adapt to the tool magnetic head of different bill identification and the mobile phone of magnetic head interface circuit by downloading special JAVA recognizer.
Background technology
At present, the magnetic printing technology is widely used in the false proof of occasions such as ticket, monthly ticket, stamp, check, invoice and commodity, and particularly the 4th edition RMB also used this anti-counterfeiting technology.
See various fictitious bills and false commodity in the time of in the daily life, but a lot of people lack the general knowledge of differentiating true and false bill and commodity, for example the elderly and minor, careless slightly will having dust thrown into the eyes.Though use the true and false or other verifying attachments of money identifier check RMB in a lot of process of exchanges, these devices can't carried when going on a journey outside and use, in the time of this can only the time go resolution by artificial experience, very inconvenient.And current multiple anti-counterfeiting technology is used comparatively inconvenience, must put through telephone for special use when for example inquiring by telephone and will quote a lot of password, and this is in that the line is busy and do not have under the situation of phone very inconvenient.The equipment of adding the various magnetic anti-counterfeit information of identification generally is that uncurrent identification to magnetic anti-counterfeit information needs specialized apparatus, and this equipment price higher (about hundreds of unit), use face is narrow, and most users can not purchase.
Also have some to be easy to carry, and the also not high banknote tester of its cost, as the invention bulletin CN 1457206A of the People's Republic of China (PRC), this disclosure of the Invention a kind of Mobile phone with device for checking money.The present invention is applied to the currency examine technology in the mobile phone, mainly realize cash examining function by circuit such as photoelectric sensor 1, magnetic sensor 2, currency examine light source 3, microprocessor 4 and displays 5, it is nimble small and exquisite to have brought into play mobile phone, easy to carry, widely used characteristics are for currency examine at any time provides instrument very easily.
Even so, but this invention can only singlely fixedly be applicable to a kind of concrete currency examine, its cash examining function is more fixing, can't be suitable for various concrete conditions variations and function singleness (simply with mobile phone and magnetic cash inspecting machine simple combination, adopt hardware identification, do not make full use of the characteristics of handset structure, simultaneously there is not fully to disclose the particular circuit configurations that mobile phone combines with the magnetic banknote tester) yet, if particularly banknote correcting or need test foreign exchange then turn turtle, and can't verify fields such as other bills, commodity.In addition, magnetic Mobile phone with device for checking money of the prior art owing to be to adopt hardware identification, therefore is not easy to dynamic tariffing and management, adaptability and limited expansibility.
