What does the type of NFC tag supported mean? NFC tags: first contact

NFC (Near Field Communication) technology is now often victorious in all spheres of life of a modern person. Z її її vopromogoyu you can vykonat yak low basic dіy - pay for travel near the subway, shopping in stores, and so forgive the process of rozvag, for example, with one hand zavantazhit book. Businesses are especially encouraged to equip their business cards with NFC tags.

Robotic principle

NFC tags are called “passive attachments”, even if they don’t stink right away, if you don’t know two minds: you can’t live, the tag is in the activation zone. The stench cannot tell the information themselves, as it is necessary to convey it. Tags are less likely to transmit information to active attachments, for the help of which you can use notifications, for example, for the help of a smartphone.

To sleep the mark, to stop the electromagnetic induction. Practically similar technology is being developed for robots chargers type A4WP. Here, behind the magnetic field, there is an “active attachment” - for example, a smartphone. The field appears behind the shell of a small cat with a dart, which vibrates the magnetic field. The stench is located perpendicular to the flow of the snake strum near the dart.

If you regulate the strength of the magnetic field, you can change the number of turns on the coils or increase the strength of the struma. Shards of such a robot help to get a lot of energy, it is impossible to admit that the number of elements that help you, was bigger. For that reason, NFC works less on the size of a few centimeters. On the vіdminu vіd Bluetooth or Wi-Fi, yakі allow you not to go to the annex, which distributes a signal close, NFC can be used only on a small stanі.

Passive extensions, that are the marks themselves, work exactly on the spot. Like such a mark is consumed by the magnetic field, by the primal coil we have a strum. Ignorantly spend on electricity, what are you blaming, small windows allow unicating pardons and transmitting a signal to do it clearly, so that you can send a song. The circuits themselves are tuned to the specified frequency, which increases their sensitivity to signals at a new one.

See NFC tag

In the whole world, NFC tags follow the ISO 14443 standard, which can be two types - A and B. The most common standard is for contactless smart cards, which allow you to pay for travel. Such standardization and breadth of technology in the whole world allows NFC to win with different devices.

Іsnuyu mitki chotiroh types, yakі vіdіznyayutsya less than the speed of transmission and obligatory data, which stench can save. The tags of the 1st and 2nd types have 48 bytes and 2 kilobytes of memory, which means that they can transfer 106 kb/s on the built-in speed. Checking with the showmen modern technologies the rate of transmission of data can be ridiculously low. Prote sled razumіti, scho tags vikorivuyutsya for specific tasks - vikonati clumsy diyu. For example, a mark can send a coristuvach to a song site, and the main work with a resource of a person can be found on your own tight smartphone. In addition, the tags are expanded in such a way that they can be beaten a few times, overwriting the information.

The 3rd type of tags is based on the Sony Felica standard. They can transmit data at 212 kb/s, so take the tags for more complex tasks. In addition, the marks are not overwritten, so they are less suitable for typing a simple work. Marks of the 4th type are considered the most intense, although the stench is also protected from overwriting. Such tags transmit data at a speed of 106 kb/s to 424 kb/s, they have 32 kb of memory for recording information.

Alternative NFC tag

Vivchayuchi all advantages and shortcomings NFC tags, How many people can supply power, isn't it easier to win Bluetooth technology? You won’t be afraid of a person to apply attachments without delay to the mark, check, docks of the mark to appear in the singing radius of recognition. In other words, NFC tags are smartly meaningful.

For example, when paying for goods it is not necessary, so that payment data can be easily scammed, even if it would break the hands of hackers. In addition, the connection with NFC attachments is expected to be mittevo, it is not necessary to check, until one knows otherwise, but it is important for the improvement of the service that the service has been set. It is enough to guess the process of passing the turnstiles at the subway during the rush hour.

Labels are easy to put on not only at the card, but also at the business card, labels of goods, special bracelets, price tags that are practical on any object. Such tags can contain data about the product, person, phone number, URL and other information.

Where can I buy tags

First of all, nfc tags can be bought on various Chinese sites in the “gadgets and accessories” distribution. They are sold in small batches (10 pieces each), you can find the best options for 100 and more tags. It is important to read all the information about the activity of the mites and the way they are programmed, as well as the intelligence.

For the average variant of skin marks, it can cost 20 to 40 rubles, but if you buy them in bulk, then it’s much cheaper. In addition, tags are often sold in the salons of stiletto zv'yazku.

NFC tags came before me, I started experimenting with them. I'll try to describe here what NFC tags are and my first message in the phone.

NFC (Near Field Communications) - to get a new one, but already widely used is the ability to communicate on an arc of a short distance - 3 - 5 cm. frequency is 13.56 MHz, the hour of setting the day is selected from 0.1 h, the operation mode is point-to-point. You, sing-song, used NFC for children on the butt of turnstiles in the subway or public transport.

NFC controllers are often integrated into smartphones at once, for example, most Lumia models or Android-based phones have been stinking for a long time. And the axis of the “best-of-breed” phone, the meanings of an apple, traditionally passed in the tail - NFC is in the iPhone 6, but its ability is greatly reduced, more in Cupertino it could be considered “uncommon”. Therefore, the iPhone is on the side and we will try it on normal devices.

Also, NFC can be active (controller on the phone), and passive, they are called tags or tags. Ring out, just a thin chip with an antenna, vdrukovani directly into paper or plastic. Vіn not maє dzherela zhivlennya (batteries), vіn takes energy from the field induced by the active controller. Metro cards The stench is even cheaper, the retail price for “clean” marks is 20-30 rubles, and you can also take it in bulk. then it is 3-5 times cheaper.

On each chip, you can write a lot of different information, but not too much: from 140 to 512 bytes. It seems that it’s more, but I didn’t specially shukav and the stench is much more expensive.

Required for recording special program on the phone, for example:

The recording process itself is even simpler: you need to select the type of notification, you can enter additional parameters and add a tag to the phone. The phone is picked up and that's all - the mark is recorded!

Tipіv pov_domlen dosit rich, ale rich hto lie down in a particular OS. For example, in Android, you can write down the access key to Wi-Fi, and the phone will immediately be set up and connected, but in Windows phone such a focus will not pass! Maximum can be written text messages with the Wi-Fi key, that command on the required side is set. Maboot, the retailers pokahuli taka on the outside on someone else's Wi-Fi Merezha unsafe. You can write down whether the URL is how it appears in the browser, checkin in social measures, phone number, which you need to call or SMS.

But more than me, the ability to open a practically be-like program on the phone was vouchsafed. Tobto, put the phone down to the mark, the program was immediately needed (so first check the box “I trust this program”). For example, often glad to stick a label to jetless charger in the car. Tobto, you insert the phone at the trimach on the windshield, the wine stops charging and the navigator turns on the new one.

I'm still sticking the tag in my notebook and now, if I come to work, I take out the phone and put it on the notebook, the list of tasks for today is displayed on the phone.

NFC (Near field communication)- (“near contactless call”) - technology dartless sting a small radius of distance, which gives the possibility of exchange of data between outbuildings, which are located at a distance of about 10 centimeters.

In my article, I will not go into detail about those who are powerful NFC technology, on the Internet, there is a lot of information about everyone. I want to show you how you can beat it in your car to those who have this function in their smartphones. Quite a lot of automobilists sing their phone like a navigator, sing with a bluetooth headset. So the axis, to speed up the navigator, you need: turn on your smartphone GPS, mobile internet(sob traffic jams were shown), run the addon; To connect to the headset, you need to turn on bluetooth, etc. All tse zmushuє vlasnik robiti richly be-yakikh diy. NFC helps to speed up all the changes to a minimum, you will need to add your smartphone to the so-called nfc-mitzi(our type has such a sticker, in which the code is recorded), and the smartphone turns on everything you need for you.

Stopping NFC tags in cars

I have a smart phone THL 5000 that program.

1. We go into the settings and reconsider that NFC is enabled.
2. Run the NFC ReTag PRO program.
3. It says “Tap the tag”, put the phone to the tag ( back part, because there is an NFC antenna).
4. If the tag code is entered, I will enter the name in my mind: - In the car.
5. We pressed "+ Diya" and chose what we want to work, in my mood: bluetooth - on, mobile data (internet) - on, GPS - on, program launch - CityGuide.
6. We press OK.

Now, if we get into the car, just put the phone to the tag, and everything in us will automatically turn on and start CityGuide. Tsyu first mark I glued right-handed on the kermi.

Exactly the same procedure is carried out with another mark: we enter the name, in my mind: - “Viyshov from the car”, only the replacement of the inclusion is chosen - vimk. close the supplement - CityGuide.

Now, when we get out of the car, we put the phone to another mark, and everything automatically sounds and closes CityGuide. I glued the tag to another on the kermi with a levoruch. Before speech, with this program (NFC ReTag PRO) you can create triggers without using NFC tags, for example: turn off bluetooth if your headset is turned off (if you yourself know that turn off the headset).

To call respect, for deyakyh diy (for example, without intermediary warning and warning of GPS and closed programs) you need ROOT rights! One more thing: the phone screen can be unlocked!

Nasamkinets, a video about how NFC tags are used in cars.

Video

Z NFC chip), on your extension, you will see a song taken by you. For example, it's a miracle butt of how NFC can win in a wonderful life - just bring your phone to the payment terminal and everything else will be broken for you.

However, it is more practical to use NFC, less money to pay. One of the good applications is the Android 4.0 feature, which is called Android Beam. Vaughn allows two possessors NFC phones transfer data one to one, simply by pushing them together.
Another example is NFC retrieval for recording and reading data on NFC tags for further retrieval of different commands of the koristuvach.
I especially use NFC tags for automating simple tasks for a few months, and I am guilty to say - do it manually. So I sing on my phone and planner for singing speeches, but in the days of NFC, such a couple can sing and may be unrealistic.
We also respectfully marvel at the programs, like I used to record and install NFC tags.

Programs
In the first hour, we need a program, so that we can do the task and write it down at the mark. In fact, on Android 4.0.2 (I'm rooting for it myself), we really need two programs. One for formatting (clearing) the marks, and the other for compiling that record of data. As far as I know, even now on Android x.4, even though there is not much sleep, and you can easily use only one add-on (my stats have a different one). All programs, about which we have been told, can be free of charge in Google Play.

TagWriter

I am vicarious TagWriter for one reason: only for formatting tags, their cleaning
Obviously, it's not the only thing, but TagWriter can work. You can write down the tags exactly. It’s just that the wine is not like a fully functional one, like an addendum, about which I’ll tell you further.

Trigger (NFC Task Launcher)

As you can bachiti on the screenshots, I already managed to add a copy of the switch to the order for a further record. What is a jumper, feed you? In two words, these commands, so you can write on NFC tags. For example, you can write an "Intro" jumper, which, when activated, will select the next command (or the sequence of commands). Then, if you press the button again, you can select different commands (or a series of commands). We'll talk about tse trochs every now and then.

In fact, NFC Task Launcher is a very simple program for writing data to NFC tags. You can create and record different alarms, including switching on Wi-Fi, Bluetooth, air-to-air mode, as well as changing sounds, different system settings, vibrations, changing alarms, modem twirling, checking and launching social add-ons, management, tweets run the program, change the display parameters (sharpness, etc.) and put the task in the planner (which is pretty weird).

Now, if you know what we can do, let's take a look at the marks and how the stench works, and also how simple it is, like a vicarious leather day.

Sleep time!

One of the places I know zastosuvannya mitkam - beat my lizhka, I vikorist tsyu mitku before going to bed and if I roll over. In the evening, when I go to sleep, I use my phone to the point, my ringtone changes to more ... calmly, and the volume of the call automatically changes and wakes up to equal 2 and the auto-brightness of the screen is set. As I already said - it’s just a task, but I’ll work it out by hand today, it would be richly weary, I’ll just put a mark.

If I'm throwing a lie, I just pick up the phone once for another caller. I change the mode, and also change the brightness and set my melody back to the one that was sleepy.
Tse everything is simple, but it’s more scary.

Go in for sports

Let's talk about finding NFC tags on my bike. I often start my day with a ride on a bike, that’s why there’s a mark, like switching radio stations or playlists in the player and launching a bunch of add-ons and languages.

As you can see, my phone is the key part of my ranking. After the dot to the mark on my bike, I put the phone at the holder on the frame, turn on my Bluetooth headphones And now get ready for the journey. I don't like to get excited about reminders or tweets - the volume level is automatically changed to a minimum and vibration is turned on. Also, in such a way, I will save a little bit of my hour.

As soon as I turn around home, I activate the tag again, picking up another switch. Wi-Fi is enabled and the phone is connected to home measure, turn on all sound signals and vibrate. Really, the only thing that I have to do manually is to do it automatically launched addenda. I can live from cim.

In the car

This is one of the simplest signs of success that I have, and only one, as there are not any jumps. It turns on Wi-Fi, changes the volume of music to 13 and launches Google Music. I'm not a vicorist program for navigation, so in order to add more necessary functions, you can create another jumper, which launches navigation and some other speeches, for quiet vipadkiv, if you need to go far.

Visnovok

As you can see, NFC technology is no longer fantastic. It is really practical to install NFC tags. Apply, as I have given, one of the most basic ideas, and as you have, I also recommend experimenting with different switches and adjustments.
