Once, a friend dropped by, when I realized that my phone rang in a trance due to the excessive sleepiness, I saw he called me 11 times. Thus, I rushed downstairs immediately.
Unfortunately, I forgot my access card, and we stayed in the scorching heat in summer for two hours. We didn't go in until someone used his card.
My friend told me that he often forgot the access card, but the smartwatch he wore solved his problem.
He uses Alfawise H19 smartwatch, which is equivalent to the combination of the access card and fitness tracker.
The price of the smartwatch approximates the deposit of an access card; additionally, it is also a smart sports bracelet. This watch can also record the amount of exercise, which is excellent for me because I am planning to lose weight and record the calories burnt to be fitter.
In fact, in comparison with other smartwatches at the same price range, the Alfawise H19 RFID smartwatch has the additional RFID function. That’s why the Alfawise H19 RFID can function as an access card.
So, what is RFID? What are the RFID functions of this watch?
Now, let’s learn more about RFID right now!
Generally speaking, RFID is the abbreviation of Radio Frequency Identification, which is a non-contact automatic identification technology.
It automatically recognizes the target object through RF signals and can quickly track items and exchange data.
The identification work can work in a variety of harsh environments without manual intervention.
RFID technology can recognize high-speed moving objects and identify multiple labels at the same time, which is quick and easy to operate.
The RFID technology is the successor of traditional bar code technology, also known as "electronic tags" or "radio tags."
This watch can work as RFID-enabled identification cards which control the access to a building.
It supports IC chip, 13.56Hz/M1 cards by default. The smart bracelet can write data into it for identification, so you won’t worry about forgetting the access card anymore.
Here is how to set up the function.
First, what you need to do is find the “Add card” function on the lock and set the user name, then, you click “Add card” and verify the administrator. Finally, if every step of the operation goes smoothly, the card will be successfully activated.
The moment you approach the watch to the identification area of the access control system, the door will open instantly. You don’t need to turn on the screen of the watch and find the access card.
What’s more, the identification speed of the smartwatch and the door is almost the same as the physical card.
In addition to the powerful RFID function, the smart sports watch also boasts excellent features which spice up life.
All these functions are good for health.
1.Accurate measurement function
The data measured by this watch is very accurate, making the smartwatch a good fitness tracker for sports.
Step count, heart rate, and blood pressure are the three of the critical measurements that everyone concerns the most.
The smartwatch will automatically track step taken, calories burned, distance traveled, heart rate and blood pressure measurement data, and display them on the screen.
All the fitness data are helpful, indicating the amount of exercise as well as the health condition.
In the past, when I needed to measure my heart rate and blood pressure, I would have an appointment with my doctor, go to the clinic or a pharmacy.
After using this smartwatch, I can measure the heart rate and blood pressure whenever I like. It is so convenient.
To my amazement, the accuracy is quite high, even when you compare the smartwatch with the professional instrument.
Additionally, I like achieving the daily goal, 10,000 steps. Every time the smartwatch vibrates because of that, I feel proud of myself.
As the saying goes, a journey of a thousand miles begins with one step!
This watch also supports the training mode.
In the training mode, there are various sports to choose from, such as running, basketball, badminton, football, etc.
If you select these sports, the Alfawise H19 smartwatch will calculate the calories that you burn more precisely, based on the duration and average heart rate of the exercise.
What’s more, you’ll have a time log of what exercises you have done in the past. I’ve used the smartwatch together with a weighing scale and quickly found that running was the most practical way for me to burn fat.
Thus, I stick to it, and the result is beyond my expectation.
The picture shows the fitness data that the running mode provides.
3. Remotely control functions
Apart from some essential sports functions, what you need to know is that the smartwatch also comes with some distinctive features compared to other watches — it can work as a remote control and a music player, and it can also be used as a Bluetooth remote shutter to take pictures.
It's so versatile, useful, and winning my heart.
I don’t use headphones for safety reasons. Before I used Alfawise H19 when I was running, my phone was put in the armband, to control the music, I needed to open the armband, took out my phone to switch the songs, then put it back, which was very inconvenient.
However, with this watch, I lift my wrist directly, and then I can control the music. This feature is practical! I love it!
Alfawise H19 smartwatch also functions as a Bluetooth shutter.
I am also kind of photography enthusiast and sort of narcissist. When I run, I take pictures of myself with the scenery around me as background. Not for a post on Facebook.
The self-motivation works! And I am glad to see that I look better and better in the selfie.
This screen is high-resolution and beautiful with vivid colors and nice-looking icons, so this watch is attractive to me.
Although there are still some features that I have not tested, such as waterproof level, sleep monitor, and so on, I assure you that they are perfect, offer great value for money.
Now, I am happy because I do a sufficient amount of exercise every day, sleep better than ever and have no more worry about missing calls and message.
To my surprise, I have lost 10 pounds within two months.
Finally, do you think a multi-functional sports watch is expensive?
No, it is even more affordable than most basic sports watches. The price of the smartwatch is under $30, which is incredible! Up till now, I haven't found a better and more budget-friendly sports watch than it.
I want to recommend this watch to everyone. I’ve bought one for myself, and I have also bought two more for my parents. They all think that the smartwatch is very fashionable and useful.
I believe that if you have this watch, you will like it, too!
