Pipe tracking using Passive RFID

Water Pipe is a highly concerned issue in HK recently for material safety issues. Pipe tracking is also very highly concerned in fuel and power delivery . To ensure or even enhance pipeline safety, a good tracking, recording system is required. Auto-ID system can provide a faster data retrieval  when comparing to visual methods, which data and drawing of the pipeline are hard to obtain or hard to understand. 

With RFID, Information of the pipeline network can be all stored in tiny tags that are easy and convenient to read or write by RFID reader. 

Such as below:

A tiny RFID tag with an industrial ring that can firmly hold on any rod-shape object

A tiny RFID tag with an industrial ring that can firmly hold on water PVC pipeline

RFID system can be applied throughout different processes includes sampling, construction, 
installation and usage stage and possibly provide functions like pipeline tagging, direction tracking, material record and worker maintenance record.......

If you are interested in applying RFID system in your pipeline network, there are few concerns you need to think it through:

1.  Installation method, in-situ or pre-tagged? 
2.  Weather proof of tag? how about explosion-proof?
3.  Any reading range concerns?
4.  The readers and the web-data to back up this system

Review on deco fingernail, with LED flashing using NFC

Typical deco nails can no longer satisfy ladies on pursuing beauty on their fingernail. And now even mobile technologies can also play a part in improving the shininess of the deco nails. This is one of the latest applications of NFC technology which can be defined as a perfect combination of beauty and technology.

Today, we are going to share about a latest décor on your fingernails, using NFC to trigger extra-shiny effect. Please study this carefully before you out of words in front of your girlfriend/wife who is showing off her LED blinking fingernail.

This is the little chip that provides flashing LED on deco nail, the deco nail that will light up when your fingers place near NFC working devices (or any 13.56MHz RF field). Basically, it is just a simple tuned antenna coil with a LED.

Size of the chip 

A 0.5mm thick NFC tag embedded, enables your nail flashing when you using your phone, making your payment at POS terminal or entering office/home with your contactless card.


The LED light can actually keep lighting
up, if other NFC chips that with IC are

Will it be dangerous to put a NFC & LED chip inside your deco nail?
I can say that it is nearly impossible to trigger any accident as there is no battery inside.

Will the nail be hot if it keeps flashing?
As no energy is required or generated, your nail will keep blinking without emitting any heat.

Will the NFC function drains my phone’s battery?
Switching on the NFC function for a whole day will only cost less than 5% of your phone’s battery.

Will the NFC embedded in the nail affect other devices that using NFC (e.g. octopus, access card, payment card……)?
As the NFC embedded in the deco nail is not complied with IC chip. That’s mean your flashing nail will not affect the function of other NFC devices.

Things you should know

1.         NFC only works when your NFC mobile phone is unlocked.

2.         Passive-type NFC only works on android smartphone, so if you are iPhone (any, include 6/6+) user, you can ignore this by now or you can send your complaint to Apple on why they locked up the NFC.

3.         LED deco nail also works on any proximity card reader that uses 13.56MHz.

4.         If you are using your phone, texting or playing games…. You cannot see your flashing nails since your fingers are the back of the phone.

5.         To get the best and brightest flashes, your fingers should put closely to where the NFC smartphone antenna is located (different from model to model)

6.         The only function of this LED chip is flashing only. No other use (interacting with NFC apps/storing data…..) is available.

Other uses

If you are a non-deco nail user, you can stick this LED chip to anywhere you want (access card, payment card……), it will light up when it is near any NFC reader.

Normally, it can work on Octopus, contact-less access card of your home, office….. I can sure that the LED chip will not affect the function of your card.
In our test, our octopus card can be read by the tablet successfully with the LED light blinking.

BUT sometimes there may be special cases that the chip doesn’t work well. It depends on different versions of octopus card (different versions of octopus have different structure) and different types of reader that your card and LED chip reacted with.

Just like that, it will flash when your Octopus is placed near NFC reader

Review of NODE, a multi-sensor on your smartphone

Today we are gonna to review this gluestick-like stuff.

Its name is NODE.

If I just show you the NODE, without telling you any things about it, I can guarantee that your blind guess can never be right.

It is a Bluetooth-connectable gadget that can connect with up to 2 sensors. And there is a wide choice of sensors; a whole lot of choice for sensors. Extracting the introduction of NODE from the official, it is a handheld sensor powerhouse with BLE 4.0 Smart supporting with different sensors. Each NODE can pair with two sensors at the same time.

They have 8 functions provided at this moment


The upper one is the CLIMA Module, the white sphere up there act as a mini, pocket observatory. It provides the measurement and recording of climatic information include Air Pressure, Light Index, Humidity and Temperature. It just gives you a chance to be a weatherman around your friends and colleagues. I’m sure you will become a weather-checking junkie after using the CLIMA.

OXA – CO2 & NO2 (not shown in picture)

The lower one is the OXA – CO2 Module, those tiny holes on the surface of the sensor help you to measure and record the carbon dioxide/nitrogen dioxide level around you. It is actually quite interesting to know about how good the air quality is throughout your daily life. Isn’t it?

Luckily, it shows that my working environment is within the CO2 safety level   

Well, this is empty and it is not an error NO2 level should remain zero or very low in normal environment

Now, just have a short summary of NODE, as a cutting edge gadget, NODE is really easy to use
even for a novice. Install the apps, turn on your NODE and you can have fun with it. I won’t say NODE is kid-and-grandma-friendly, yet…its aimed for student or someone who want to get a taste on mini-scale scientific investigator.

The only real problem is that NODE and their sensors remain a relative high price (for any student to own one) even though it has been released about 2 years ago. What we can do is just to hope that, in one day, NODE will move to large production runs and price will come down hopefully.
