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

If you find a button-type TM card that was invented in the mid-1990s and began to become popular in civilian places around the world at the turn of the new century.

However, the cards in the hands of Meng Songfei and his men are much larger than the common common button-sized TM cards in the future, which are 1.5 times the size of a one-yuan coin. However, the thickness is similar to that of a future TM card, and it is only a little thicker. According to Liang Yuan, the only one in the world who has seen two cards, if the two physical objects are not placed next to each other, it is difficult to distinguish the thickness by the naked eye.

Whether the counterfeit TM card made by Yuanjia becomes larger or thicker, it is the backwardness of Yuanjia's chip manufacturing technology. Of course, even if overseas is included in this era, I can't get the same thing as Liang Yuan's memory at the moment.

A real TM card invention company, Dallas Semiconductor, the United States, will only be industrialized in 1995. At that time, the chip process technology has entered the point three-five era below one micron, and there are at least three eras left.

Although applications in industrial control, industrial automation and other directions are also very important, in terms of simple chip usage, Yuanjia's core development direction of enterprises, letting chips enter life is the biggest market.

In this big market, some basic industries cannot be overcome, such as electronic water meters, electronic electricity meters, electronic access control, etc., which are currently at the forefront of the international market.

In the basic industries of these chip applications, whether Yuanjia chooses to choose magnetic cards, optical cards that are about to go out of date, or IC cards that represent the next generation of technology, it can be said that it has been suppressed by overseas technology consortiums in terms of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, almost public technology, Yuanjia lags behind overseas technology groups for ten years in other aspects such as data bus, card readers, and system integration. If you want to bypass the patented technology group of top international manufacturers such as Philips, Siemens, and STMicroelectronics, the price you need to pay to catch up with Yuanjia is not an ordinary price.

In view of this, Liang Yuan decisively chose to turn over the table and stop playing with you guys, so I started a new job.

At Liang Yuan's request, Yuanjia completely gave up the technical research and development of the contact IC card branch, but instead focused its strength on the two directions of contactless (radio-radio frequency) and button-type TM card.

Although Liang Yuan does not understand specific technology, he has used the physical objects of the TM card countless times. After specifying the use scenarios of the product and the detailed requirements of the product, Nie Xiaotian will easily solve the actual technologies that Liang Yuan mentioned to complete. With the current R&D level of Yuanjia, TM cards of the microcontroller level are not as difficult as R&D, but rather difficult in manufacturing processes. For example, the laser encoding technology required to manufacture TM cards is one of them.

Although both TM card and IC card have joined the ecological development circle of Intel 51 series microcontrollers and 8031 ​​instruction sets, the biggest difference between TM card and IC card is that the core technologies such as card collection and reading system and data bus composition are completely incompatible.

If we use simple examples to describe the difference between TM and IC cards, such as traveling from London to New York, European consortiums such as Philips, Siemens, and STMicroelectronics have monopolized flight and navigation, and these two travel methods have only left a glimmer of hope of building bridges on the Atlantic Ocean. Liang Yuan did not choose to build a bridge, but chose to take a manned spacecraft and go directly from outer space.

The technical route of TM cards is also so domineering. This guy integrates the data cable, ground wire, control wire and power cable of the contact IC card into one line, achieving the successful exchange of data with just a touch of the metal, completely abandoning the more complicated card reading method of IC cards.

Strictly speaking, TM cards are technology between contact IC cards and unlimited RF contactless IC cards. Although there is no contactless type that can be easily passed by without taking it out in various bags, it is considered to be durable and convenient, which is much higher than contact IC cards. As for magnetic cards, optical cards are completely beaten.

In fact, the Americans in Liang Yuan's plane were also unable to bear the dominant position of European technology consortiums in IC cards, so they turned over the table and created TM cards. In the 1990s, Siemens accounted for about 35% to 40%, STMicroelectronics accounted for 30%, Hitachi Japan accounted for 10%, Philips accounted for 10%, Motorola accounted for 10%, and other countries shared at most 5% to less.

Since Liang Yuan turned the table up in advance and took the American path, someone now looks forward to what other tricks the American technology consortium can do in this direction in five years.

Of course, due to immature technology, the current production cost of Yuanjia TM cards is extremely touching, including an electronic lock of 4,000 yuan, an electronic key of 500 yuan, a data acquisition card of 800 yuan, and a set of 20,000 yuan for reading and writing TM system data processing microcomputers. Although Lego bathing is down-to-earth, the cost of the locker room alone is close to three million yuan.

This is because of the locker. Data exchange centers such as water and electricity cards, access control cards, ticket cards, etc. do not need to be purchased. Otherwise, even the smallest Inspur data center will be quoted in units of 100,000 yuan.

The LEGO bath lock lock is placed in a conventional position. There is a silver metal ring that is much larger than a one-yuan coin, and the ring is flat stainless steel.

Meng Songfei, with a slight smug look, pasted the round metal plate with the number written on the card, like a metal keychain, into the silver metal ring on the cabinet.

First, a low motor sounded, and then two sounds later, the cabinet door of the locker slowly opened a gap under the push of the damping spring.

Looking around the three little brothers' stunned expressions, Meng Songfei smiled proudly and said loudly: "Please pay attention, fight hard like a cannon, use this round card to gently touch the ring."

"Damn it."

"Awesome."

"Follow Brother Fei to gain a better understanding."

Not a few people have little knowledge. Not to mention that in the current Republic where technology is underdeveloped, even if you go to Europe and the United States, there are still no induction locks. High-tech such as fingerprint locks and iris locks, the so-called electronic locks are all variant magnetic cards, optical cards, and IC cards.

In Hollywood blockbusters representing top technology, such as the 007 series currently at its peak, when shooting CIA or virtual large-scale technology laboratories, the key is a card that is already at the top of the world. Two metal pieces that seem to be unsurprisingly can turn into locks and keys. Throwing them in Europe and the United States is also a science fiction thing, and even the sensational effect may be greater than in the Republic.

Why can Mayor Fu run to Lego without caring about face and take a shower? Strictly speaking, Mayor Fu is fascinated by this thing. Most people may just think that TM card is a novel science fiction lock, but even if Fu Qili ignores the wide use of TM card for a while, the mayor's many professional subordinates would never make this mistake.

The fact is that Fu Qili, who was young and prosperous and had excellent intentions, discovered the special features of this electronic lock as soon as possible. Then the mayor directly pulled He Yunwei to the bathhouse for an explanation.
