Near Field Communication (NFC), which has been mainly used as a smartphone for electronic payment, file transfer, or traffic card, has started to be applied to Automotive's 'smart key' technology in earnest. Now it is time to open the door of the car through the NFC communication of the smartphone without a separate car key.

ST Microelectronics (ST) applied the NFC chip for smart key function to the European automobile brand for the first time in the world, and the vehicle started mass production last year. We are pleased to announce that we are pleased to announce that we are pleased to announce that we are pleased to announce that ST's NFC technology features and NFC's prospects for the automotive market will be met by Tae Young Yang, director of marketing, STMicroelectronics Memory Division.

NFC is a non-contact wireless communication technology that allows data to be exchanged within a distance of about 10cm using a frequency of 13.56MHz. With NFC, you can easily open and close door locks with your smartphone. You can easily use public transportation such as buses and subways as a substitute for transportation cards, and store coupons for shopping.

Since the communication distance of NFC is short, the user must directly touch the smartphone to the communication target device in order to exchange data. Therefore, the security is higher than RFID (Radio Frequency IDentification), which is widely used in the electronic tag. The advantage of NFC is that it can be both 'read' and 'write'. It also aims at zero power. For this reason, NFC can be used on bus cards that do not have a separate battery.

The NFC Forum decides whether to receive data from the standard NFC data format (NDEF) and Android and Windows (handover) and how to extend the Apple PayPay on the iPhone. More than 50% of smartphones will be compatible with NFC in 2015, but this is only used for Android phones. But as Apple begins to join the NFC Forum in 2015, the NFC market is likely to grow. In the meantime, Apple used NFC-based payment functions like Apple Pay, but recently announced Apple Watch at the Apple Developer Forum, which made it possible to use another NFC feature.
Taeyoung Yang said, "I expect the technology to expand more rapidly if NFC, which was mainly used in smartphones, is used by Apple as well as Android."

Automotive smart key that must be on at all times
NFC, power consumption technology is key

ST's NFC chips are largely classified into Smart Driving and IoT (Internet of Things). Automobiles are a conservative industry where safety is more important as they relate to the lives of people and must be tested for stronger security. On the other hand, it is also an industry where market expansion can be facilitated if product reliability is acquired in the industry.

In the automotive field, ST applied NFC technology to the first smart key for car doors, and the car with this technology was released for the first time this year. In addition, the NFC automatically adjusts the height and rearview mirror of the chair whenever the driver changes based on previously stored data. In addition, when an abnormality occurs in a vehicle, it is possible to use it as a diagnostic tool to notify the smartphone of the problem immediately without having to look at the manual of the vehicle.
Tae Young Yang said, "Radio communication is very important because antennas are easily absorbed by objects made of metal like automobiles. The size and design of the NFC IC is important because the handle of the car door with the antenna for NFC communication needs to be small and the design aspect should be taken into consideration. "

In addition, the car key must be always powered, so do not affect the current consumption. Therefore, the ST chip keeps the minimum power required for communication on, thus preventing energy wastage. When waking up the chip to communicate, it needs to consume less energy. ST supports both capacitive wake-up and inductive wake-up functions.

For example, the ST25R3911B's capacitive wakeup capability of ST's NFC reader IC can detect up to NFC and human proximity while consuming less than 5μA in sleep mode, and inductive wake-up is a low-power mode And senses appropriately.
Yang Tae-young said, "Disadvantages of capacitive wake-ups are waking up too often. That is, the sensitivity is excellent. On the other hand, the inductive wake-up function consumes a little more current. Therefore, ST determines the optimal ratio of the two functions for each product with the car customer. This feature allowed ST's NFC reader ICs to be adopted by automotive OEMs, receiving a score of 10 times better than their competitors in their current consumption. The ST25R3911B has about 5 times better sensitivity than typical devices and can extend its range without adding additional amplifiers with up to 1.4W of output power. "

Another advantage is that in order to amplify the signal from the antenna, the booster must be in front of the antenna. ST's product includes a booster in the NFC chip to save space. In addition, it provides automotive tuning, which protects the antenna components when they are distorted by metal.

NFC IC chip securing safety in the automotive market, unlimited use
NFC brought the advantages that were used in the consumer market, such as e-passport, payment, and hotel key, to the automotive market. The NFC technology used in Automotive has secured stability, which is why it is favorable to expand the product as the demand in the consumer market increases.

Since ST offers MCUs and other products, it has a peak that it can provide a total solution by flattening NFC. ST also supplies the ST25R3911B, an NFC reader IC, and the Discovery kit ST25R3911B-DISCO, which integrates a microcontroller STM32L476RE.

Taeyoung Yang said, "We expect NFC usage to increase in the automotive market in the future. Another wireless communication technology, Bluetooth low energy (BLE), is a disadvantage in security that coverage is wider than NFC. NFC, on the other hand, can provide secure security because it operates when the human hand reaches directly. We expect that the security capabilities will be further strengthened by adding fingerprint recognition to NFC in the future. "

In addition, the audio speaker function of most cars now uses a smart phone in conjunction with Bluetooth. Instead, the NFC function of the smartphone's wireless charger in the car will be charged and the user can listen to music through the NFC connection at the same time. In addition, it is anticipated that when NFC IC is installed at the upper end of the charging cable at the charging station of an electric car, that is, the part of the car which is connected to the car, it is possible to confirm the monthly charge at once through communication. The possibility that NFC is applied to various fields of automotive is unlimited.

What should I do when I need to use my car with someone else? An NFC smart key can give a vehicle owner a key authorization to a third party, such as a spouse. If you need permission, you can install the app on your smartphone and go through the verification process. At this time, the owner may give up only a part of the authority and prevent the risk of accident caused by unreasonable use of the vehicle. For example, a third party could have the car write at a certain time, or the door might open but not start. Hyundai Mobis developed a 'certified controller' that uses data encryption technology and authentication technology in preparation for the risk that the smart key will be hacked and the car stolen. Highly encrypted car and smartphone information prevents hacking programs from reading information and accurately verifies whether the car and smartphone owner match up. For more complete security, MOBIS plans to verify security threats even after product launches. http://biz.khan.co.kr/khan_art_view.html?artid=201803281642001&code=920508#csidx2b3b3337f0ad73bae4e0d2b58e82346

A car that can be used to open and open the car door without a key using a phone is being developed, the Wall Street Journal (WSJ) reported Wednesday. The rugged keychain or electronic key needed to open the car door and start it is now in the same position as the cassette to enter the list of antiques to be found in car history books. Several major auto parts suppliers have developed a system that can connect to a smart phone and open the door without a key. Car manufacturers also offer mobile apps that allow drivers to open or start the car remotely, but now the electronic key must be in the car before the car can move. However, if you lose your electronic key, it will be cumbersome and expensive to replace. Denso Corp., a Japanese auto parts company, announced today that it has acquired InfiniteKey Inc., a US-based software startup with patented technology that allows smartphones to open doors without a key. This key-free technology can quickly spread through Denso's extensive supply network. "Vehicles with Denso's new technology will be available to dealers in 2019," said Bill Foy, senior vice president of Denso's US operations. Hotels and other businesses are also researching smartphone apps that replace traditional keys. Keyless cars are the latest in a series of innovations that make old standard car parts obsolete, from wire antennas to dangling fuel tank caps. Manufacturers of these components also need to keep pace with this new technology. Vehicle antennas with sophisticated wireless connectivity do not appear hidden in roof mounted 'shark fins', and in newer models cars do not have caps on fuel tanks. Parts maker Martinrea International Inc., who contributed to the market with a cap-less fuel filler 10 years ago, says that 30 percent of cars sold in North America are equipped with screw cap tanks. In addition, cigarette lighters, compact disc players and spare tires are just some of the things that will remain in the foreseeable future. The keys to the car made of metal gave way to a thick electronic key or push-button, and now it's time for them to disappear. http://www.econovill.com/news/articleView.html?idxno=328505
The biggest rival in the smartphone market Samsung and Apple are expected to use the same kind of 'digital key'. Two companies are participating in a technology development consortium that can use smart phones like car keys. According to industry sources, the Car Connectivity Consortium (CCC) group, which Samsung and Apple are part of, will launch a 'Digital Key 1.0' system that can use smartphones as a car key, (Local time). According to CCC, digital key 1.0 allows you to open, lock and start your car through the smartphone app. Because it uses Near Field Communication (NFC) technology, it can be used even a few steps away from the car. In addition, other settings allow you to have access to your car even with someone else's smartphone. This technology is expected to be used in emergencies, ballet parking and car sharing industry. "The digital key we provide is very popular with a lot of people," said Maffir Rahman, CCC group president. Leading global innovation for smartphone-based automotive connectivity solutions, the CCC Group is an organization in Oregon, USA that focuses on developing systems such as 'digital keys' using smartphones to help people get more comfortable with their cars. . CCC is also known as MirrorLink ™, a solution that links bi-directional links between smartphones and in-car displays. Rahman said he has "the best security system" for Digital Key 1.0, and showed strong confidence in the security issues people might be worried about. "We used the same NFC chips used in our existing Android and iOS smartphones and based on TSM (Trusted Service Manager), so we have thorough security from start to finish even when connected to mobile apps," he said. The digital key service can be used for all vehicles belonging to the CCC group such as Hyundai Motor, Audi and BMW. Volvo cars have also been applied for, but have not been commercialized yet. The CCC group has already begun developing the next step, 'Digital Key 2.0'. The market launch date is scheduled for the first quarter of 2019. Rahman said, "Digital Key 1.0 already boasts a strong influence in the market." Digital Key 2.0 is expected to have even greater impact.

When the driver puts the smartphone on the handle of the car door, the near-field wireless communication (NFC) receiver mounted inside the door recognizes the signal of the smartphone and opens the door. After sitting on the driver's seat, put the smart phone on the car stand, press the start button, the wireless charging starts and the car and the smartphone are connected with Bluetooth. As NFC technology is applied to car keys, driving habits are changing rapidly. According to the industry on November 11, NFC technology, which was developed in 2002 and used mainly for transportation cards and credit card payments, has been expanded to car keys, and smart phones are turning into car keys. NFC is a kind of electronic tag (RFID) that transmits and receives bidirectional data by bringing two or more terminals close to each other. In the second half of last year, Mercedes-Benz E-Class was the first to adopt the first type of digital key using NFC. Hyundai Mobis participated in the Consumer Electronics Show (CES) held in Las Vegas in January and introduced the NFC-enabled digital key system. When NFC technology is applied to a car key, the driver automatically adjusts the seat according to the driver's body type, and the smartphone screen cooperates with the display of the car to reproduce the usual favorite music according to the driver's voice command. When you turn off the car, you can see the status of the car, the driving record, and the parking position, etc. The proliferation of car digital keys has a side to prepare for the expansion of 'car sharing' service, which will be coming soon. If autonomous vehicles become commonplace, autonomous vehicles can be obtained in a short time through smartphone applications, and it is more convenient to share the car than to own it. It is an analysis that digital key using smart phone will be utilized for such car sharing. In some cases, there is a concern that smartphones can become targets of hackers if they replace their car keys. However, it is safe to apply advanced encryption techniques used in financial settlement to automobile digital keys http://www.hankookilbo.com/News/Read/201809101443388972
