Description

-M367382 Repeatedly, the new type of description: [New technical field] ·· This creative department provides a license identification machine with multiple file inputs, especially after the user inserts the card and the identification is successful, the radio frequency card can be placed. And after entering the security password on the keyboard, you can operate the automatic trading machine to buy and use ', and use this double confirmation to improve the anti-theft effect. '[Previous technology] • According to 'the development of today's social science and technology, shortening the distance between people, but also speeding up the pace of people's touch, making human beings tend to be convenient and fast in the requirements of life (four) 'in many public In order to consider the convenience and speed that modern people pay attention to in the place, there is an automatic vending machine II. By automating the vending machine, not only can the personnel be greatly saved, but the convenience is more convenient for modern people. Automated vending machines from the most common beverages, cigarettes or ticket vending machines to the ice cream, people tickets, hard fries and ramen vending machines, have been sold to date, and more and more varieties have also been formed. Many virtual stores 'emphasize the unmanned classics # and self-checkout methods, will bring the people to the freedom, and provide the _ material-like experience. P, the object of the general vending machine does not have the age limit 77 automatic rebel buying machine items, such as: fragrant, alcoholic drinks, condoms, etc., making juveniles or children, easy to Age-restricted merchandise is available in such vending machines, and even some vending machines may be sold - some items such as medicines, ship cleaners, blades • M367382-6; /1Η V; or More dangerous controlled commodities, etc., not only lead to the growth of n or less, but also cause physical and mental health, and it is expected to cause unscrupulous people to be easy; The reason is blamed for the inability to make an age-identification for consumers. Therefore, it is necessary for manufacturers to design vending machines that can be purchased for consumers' age restrictions. Therefore, such vending machines need to add a license identification device to allow consumers to insert personal cards (such as driver's license, ID card, health insurance card). ,

I,, etc.) After the 'determination of the actual age and identity of the consumer', it is determined that after the age of 18 or the actual identity, the vending machine that sells the mosquito product or controlled goods can be used. However, some unscrupulous persons Using computer scanning, copying, cutting, and printing to make sophisticated cards to complete the misuse of miscellaneous and age, so the card identification device set by the vending machine should have multiple identification functions, so how to do it on a card Identification of different feature parts (such as watermark, paper, personal data, etc.), or multiple identification processes to allow people other than the original cardholder to use the card, even if they get the card, it is also the future of the vending machine. One of the other priorities of R&D. In addition, with radio frequency identification (R F ID ; R a d i ^

FreQUenCy Identif ica/^n Continuous research and development and progress 'The daily use of the paper card and contact type magnetic card used by the company has been replaced by the non-contact RFID card.' SI paper card has (4) The shortcomings of wet or material damage, but the contact can be sensed. The county is affected by the magnetic object and the data juice is * * M367382. When the paper card or magnetic card is to be used, the card must be taken out first. Contact induction, and extremely inconvenient 'its wireless shooting _ knowledge stored value card can be read at the predetermined distance of the card reader, Chengjin Machinery should read, and then they will not practice the RF identification stored value card from the wallet oblique bag and other materials. It is possible to carry out the money and reading of the stored value card of the radio frequency identification card. The convenience of recording on the secret use is that when the wireless radio_age card is launched, it is greatly loved by people, and more likely to be in the existing The card (such as driver's license, ID card, health insurance card, passport, etc.) adds wireless radio function, allowing users to carry the single-card with them to identify the identity data and consume it. ° However, the existing vending machine on the county has a recording side identification function 'and because of its large size, the machine can not be used inside the existing vending machine', which not only limits the use of the RFID card, but also Due to the high price of the stored value machine, it is impossible to spread to all corners of society. Therefore, the shortcomings of the above-mentioned various technologies are the subjects that those who are engaged in this industry are eager to improve, and they need to be made by the side players - New Zealand and innovative design. [New content] Therefore, the creators have designed and produced this in view of the above-mentioned _ and lack of details, which are based on multiple trees, and have been evaluated by many trees. It can be used for double confirmation to enhance the integrity of the literary scale. The main purpose of this creation (four) is that the shell is mounted on the top of the panel (4) with M367382 keyboard, the coffee maker inserts the card in the slot, and the card is swiped to make the lion ^ = and after the seam is not _ frequency card, It is expected that the automatic kingdom password of the money silker will be allowed to carry out the Qing, because the card and the ^RF card can be used, m drink _ can be stored value, through this double-layer confirmation procedure, you can Let the card other than the original card holder not be able to operate the card and the value of the radio frequency card.

2 Trading machines to make purchases' not only enhance security but also protect consumers' rights. The second purpose of this creation is that the keyboard is provided with a waterproof ring on the periphery of the transparent miscellaneous holding groove, and a waterproof sheet is arranged between the keyboard and the rear plate, and the waterproof I flip cover and the waterproof sheet have a true Isolation and blocking the effect of the external water droplets 'so that the second circuit board will not be affected by the external water, the short circuit 2 is damaged, and the coffee hood is easy to hide and stain, so the keyboard can be kept clean. Neat appearance, and then achieve the effect of waterproofing and anti-fouling. The other purpose of this creation is the secret, the gambling body is wearing the wireless surface group of the jig plate of the fiscal gear and the space formed between the coil plate and the circuit board. In order to align the slot, the user can also insert the radio frequency card from the slot to operate the automatic trading machine to perform the purchase action, and the scaled RF card of the storage surface can be read and deducted. And the library movement action axis does not touch the cards such as the passport, driver's license, and ID card, which can improve the applicability of the license identification machine. 6 M367382 ------- I , ; [Embodiment] ______ *** .丨1丨_ __ __丨f Well- v In order to achieve the above purposes and effects, the technical means used in this creation and its.
