Also, I'm the associate director of sales at Nexqo. I've been working in Nexqo for almost 10 years. 10 years ago, if you ask me what is RFID, what is NFC, what is locking system, my answer would definitely be, I don't know, I don't know, and I don't know. But now, I can not only explain what RFID and NFC are, but also can tell you the difference between them, and how you can use them in your industry, and your daily life to build an IoT world. I love traveling, and before getting into this industry, I would never know how hotel key cards and transportation ticket works. I love visiting all kinds of amusement parks, before getting into this industry, I would never know why a normal silicone wristband has so many functions. I love shopping - women, you know - but before I got into this industry, I would never know how the anti-counterfeiting could be simply realized with just a tap with an NFC smartphone. Realizing that many people don't know anything about RFID - but the fact is RFID is now everywhere in our life - in order to show them how amazing this technology is, I decide to write some articles about it. And I'll try to make it easily understood as possible I can. Don't worry that you couldn't follow me, if you do, that's definitely my bad, then please feel free to contact me for further discussion; if you disagree with any of my opinions, welcome to argue with me any time.
