Here we depict the origination of anti-faking effect. In a word, if a thing is valuable then people would like to pay for it, for example, Apple iPhone. Since it is profitable, the original manufacture will protect them to be reproduced. There are several methods to protect original makers or inventors' right from being re-produced. Patent right is the first way to protect inventors' ownership. However, the right of patents is only twenty years at most. After twenty years of patent right then it will become public domain meaning everyone can reproduce them. Therefore, there is another way to protect original owner's right. The products being made with higher cost or not possibly being copied. Laser hologram is a most used method to protect the original manufacture's right.How can a product not be reproduced? It is dependent that what the cost to re-make it is. When the re-produced thing has much higher cost or not profitable, then there is no one willing to do faking product. This is why we make the anti-faking products by using novel semiconductor IC tooling and process. This is the first time in the world that to solve the tough issue of anti-fake products using novel semiconductor equipment and process, as expected that to re-produce similar products will become not feasible or too costed.

Author: Kung Linliu, Ph. D. The RFID is a great invention for many fields of applications such as anti-fake for groceries and goods, door access key, car key, book burrow and return of library, animal identification, inventory management and luggage or cargo tracking, etc. RFID will provide a fast and precise method for identification than bar code scanning. However, the cost of RFID tag is more than that of a bar code since the RFID IC is made by semiconductor fabrication for mass production.The process and manufacturing methods are described for more detailed discussion. And the final cost down of RFID tag is discussed with chipless method using inkjet printing technology. All printed RFID tag is not yet mature technology for mass production due to many reasons is depicted in this book.Lots of efforts need to be inputted into this field to solve the cost of a RFID tag for the method of mass production.

Relative to the piezoelectric inkjet printhead, thermal bubble inkjet printhead has some disadvantages, such as the high heating temperature and the short lifetime expectancy. However, there are some advantages of thermal bubble inkjet printhead, the lower cost of manufacturing. Thus, how to use advantages and improve the disadvantages, then there is a chance to compete with piezoelectric printhead. For example, the solvent-based inks are used almost for all piezoelectric inkjet printheads rather than thermal bubble printhead. Therefore, Hewlett-Packard has developed a special ink, named as the Latex ink. The Latex inks are aqueous inks and after printing and heating up at some temperature, it then can adhere to non-porous substrate such as plastics and glass as the solvent-based ink. The water-based inks are more environmentally friendly than the solvent-based inks. As a result, Hewlett-Packard has also improved the disadvantage of thermal inkjet printheads and turned it into an advantage, but Latex inks cost more than solvent-based inks. The price of Latex inks might be lowered down if they are at mass production, and perhaps new innovative processes or innovative materials that can improve the cost of Latex inks in the future. Therefore, the cost of the Latex ink can be reduced again and it can compete with the solvent-based ink. In fact, those new or cheap technologies will replace old and obsolete technologies. However, the environmental factors may become essential and necessary, knowing the pros and cons of various technologies, the availability and inability of a wide range of materials, understanding the trends in industries and knowing the needs of business and industry is what the authors hope that readers can get more inspiration from this book.

RFID applications are widely used in many fields such as cellar phone, airport luggage, NFC money security, car keys, door keys, grocery checkout, inventory management, etc. Japanese convenience store is the first use RFID for checkout in the world. However, there is compensation from government due the shortage of man power in Japan. Long time age, Walmart announced that their supermarket will use RFID if any vendor can provide 1 cent per tag. However, there is no any vendor can provide that price to anyone.Since a RFID tag needs an IC for ID, antenna for receiving or sending signal and finally the process of packaging for IC attached on antenna. Typically, it costs one cent for each component IC and antenna and packaging process.There is a possibility for a tag to decrease cost for manufacturing a RFID if there is no packaging process which is chip less RFID. Chip less RFID or all printed process of RFID, it is now not possible yet for manufacturing vendors. More efforts need to be engaged in this field, IC manufacturing method by inkjet printing technology and materials for process of inkjet printing the memory and logic units. The last factor but the important one is that the rule for RFID might be not very applicable for the future chip less RFID and then it will need revision for the all applications.Continuous innovation and hard working to grab the marketing and success!
