The cards that Meng Songfei and the others received were very different from the various electronic card locks that were common in later generations.

If you look for the one with the highest similarity, it is the button TM card that was invented in the mid-nineties and began to become popular in civilian places around the world at the turn of the new century.

But Meng Songfei's hand in the hands of several people, can be much larger than the common ordinary button size TM card in the future, enough to have a dollar coin 1.5 times the size, but the thickness is similar to the future TM card, only a little thicker, according to the world's only two kinds of cards Liang Yuan observed, if not the two physical objects placed next to each other for comparison, it is difficult to distinguish the thickness only by the naked eye.

Whether the copycat TM card made by Yuanjia is bigger or thicker, it is the pot of backward Yuanjia chip process technology, of course, even if you count overseas in this era, you can't make the same thing as Liang Yuan remembers.

The real TM card invention company, Dallas Semiconductor in the United States, did not industrialize the production of TM cards until 95 years, and the process technology of the chip has entered the era of point 35 below one micron, and the gap between it is at least three times now.

Although the application of industrial control and industrial automation is also very important, as far as the simple chip usage is concerned, the core development direction of Yuanjia's enterprise is the biggest market for the vision of bringing chips into life.

In this big market, some basic industries are insurmountable, such as electronic water meters, electronic meters, electronic access control and so on, which are still at the forefront of the international cutting edge.

In the basic industries of these chip applications, whether Yuanjia chooses to choose the magnetic card and optical card that are about to expire, or the IC card that represents the next generation of technology, it can be said that it is pressed to death by overseas science and technology consortiums in terms of patents.

Although one of the core technologies of IC cards, Intel 51 microcontroller instruction set has been sold all over the world and has almost become an open technology, but in other aspects such as data bus, card reader, system integration, etc., Yuanjia is fully behind overseas technology groups for ten years, and the price that needs to be paid to catch up with Yuanjia is not ordinarily large.

In view of this, Liang Yuan decisively chose to flip the table, no longer playing with you bosses, Lao Tzu started a new stove.

At the request of Liang Yuan, Yuanjia completely gave up the technology research and development of the branch of contact IC card, but concentrated its strength on the two directions of contactless (wireless radio frequency) and button TM card.

Although Liang Yuan does not understand the specific technology, but the physical object of the TM card has been used countless times, after specifying in detail the use scenarios of the product and the detailed requirements for the use of the product, Nie Xiaotian will easily figure out what technologies are needed to complete the actual product in Liang Yuan's mouth, with the direction of research and development, in terms of Yuanjia's current research and development level, the TM card at the level of single-chip microcomputer is not so much difficult to develop as it is difficult to say that there are difficulties in the manufacturing process, such as the laser coding technology required to manufacture the TM card is one of them.

Although TM card and IC card have joined the ecological development circle of Intel 51 series microcontroller and 8031 instruction set, the biggest difference between TM card and IC card is that the core technologies such as the acquisition and reading system and data bus composition between the two are completely unrelated.

If you use a simple example to describe the difference between TM card and IC card, such as the trip from London to New York, Philips, Siemens, STMicroelectronics and other European consortiums have monopolized the two modes of travel such as flight and navigation, leaving only a glimmer of hope for building bridges in the Atlantic, and then Liang Yuan did not choose to build bridges, but chose to take a manned spacecraft directly from outer space.

The technical route of TM card is also so domineering, which integrates the data line, ground wire, control line and power line of the contact IC card into one line, so as to achieve the link of successful data exchange as long as the metal is lightly touched, and completely abandons the more complex card reading method of the IC card.

Strictly speaking, TM card is between the technology between the contact IC card and the unlimited radio frequency contactless IC card, although there is no contactless kind of convenience that can be taken out in various bags without taking it out directly, but it is durable, convenient and other factors are much higher than the contact IC card, as for the magnetic card, the light card or something is completely hanged.

In fact, Liang Yuan's last plane of the United States is also the European science and technology consortium in the dominant position of the IC card can not bear to flip the table to make the TM card, in the nineties IC card market share Siemens accounted for about 35% to 40%, STMicroelectronics accounted for 30%, Japan Hitachi accounted for 10%, Philips accounted for 10%, Motorola 10%, other countries trash fish share up to 5% or even less.

Because Liang Yuan lifted the table in advance and took the path of the old United States, someone now is particularly looking forward to what the American science and technology consortium can do in this direction in five years.

Of course, due to the immaturity of technology, the current production cost of Yuanjia TM card is unusually touching, including 4,000 pieces of an electronic lock, 500 pieces of an electronic key, 800 pieces of a data acquisition card, and 20,000 pieces of a set of data processing microcomputers for reading and writing TM systems.

This is also due to the fact that it is a locker, and the data exchange center required for water and electricity cards, access control cards, ticket cards, etc., does not need to be purchased, otherwise even the smallest Inspur data center, the price is quoted in units of 100,000 yuan.

The Lego Bath Locker Lockhead is conventionally placed in a silver metal ring much larger than a dollar coin, and the ring is made of flat stainless steel.

With a slightly smug look, Meng Songfei attached the round metal piece with the number written on the card in his hand, like a metal keychain, into the silver metal ring on the cabinet.

First, a low motor sounded, and after the next two sounds, the door of the locker opened a gap unhurriedly under the push of the damping spring.

Looking around at the stunned expressions of the three younger brothers, Meng Songfei smiled proudly and said loudly: "Pay attention, don't be scareless, just touch the ring lightly with this medal." ”

"Holy. ”

"Awesome. ”

"I saw it with Brother Fei. ”

It's not that a few people have little knowledge, not to mention that in the current republic where science and technology are not developed, even if you go to Europe and the United States, there is no induction lock, fingerprint lock iris lock and other high-tech, and the so-called electronic lock is also a variant of magnetic card, optical card, IC card.

In Hollywood blockbusters that represent top technology, such as the 007 series, which is currently in full swing, when filming the CIA or a virtual large-scale technology laboratory, the key is a card is already the world's top level, and it seems that two pieces of metal can be turned into a lock and a key, and throwing it in Europe and the United States is also a science fiction thing, and the sensational effect may be even greater than in the Republic.

Why can Mayor Fu run to Lego to bathe without caring about his face, strictly speaking, Mayor Fu is fascinated by this thing, ordinary people may only think that TM card is a novel sci-fi lock, but even if Fu Qili ignores the wide use of TM card for a while, the mayor's vast number of professional subordinates will never make this mistake.

The fact is that Fu Qili, who is young and energetic and has an excellent heart, discovered the peculiarity of this electronic lock at the first time, and then the mayor directly dragged He Yunwei to the bath to explain.

There is no way, Su Liangyu, Lu Hengsheng and others all went to Europe because of the Wafer process equipment, Li Yuanling never interfered in the business in the direction of Yuanjia Electronics, and Liang Yuan did not have the leisure to deal with the local parents, so he could only be He Yunwei.
