Keyword Trends – NFC vs IoT

** This blog was originally posted in LinkedIn on March 17th, 2016

In March 2015, I posted an article on the NFC Mobile Payment Trend in order to discuss the NFC Mobile Payment movement. Today, I did another trend analysis and want to share the data and insights.

It looks like “NFC/Near Field Communication” is still an interest and India is still the number one place that is interested in the technology. A search for “Mobile Payment” remains flat and the “Apply Pay” search went down after the initial launch in November 2014. To show the relative interest, I plugged in “IoT”. You can see that interest is picking up after 2015 but I am surprised to see the search trend is relatively low vs NFC.

India’s strong interest in NFC is not surprising. When you have a chance to read my post on “NFC In Action in an IoT World”, you would learn that NFC is making a huge difference in rural areas of India and saving children’s lives with the application of the Khushi baby (KB) necklace.

This insight encourages me to update my book, “Everyday NFC: Near Field Communication Explained”, to the 3rd edition since the interest remains high and NFC enables tons of connectivity in the IoT world. Please let me know if you have any NFC product or service to share with me and my readers.


A Smart Lock – NFC enabled Secure Access Control

** This blog was originally posted in the LinkedIn on March 1st, 2016

In February, I stayed at the Best Western Hotel twice; once in Vancouver BC and once in Denver. In BC, I noticed that I was given a chip card to unlock my hotel door by tapping the lock. In Denver, “ASSA ABLOY” was printed on my Best Western chip card so it became clear to me that Best Western has adopted the NFC technology from Assa Abloy.

Assa Abloy has been the leader for door opening solutions. The newer technology has been moving from using NFC chip smart cards to mobile keys; i.e. using your mobile phone to unlock the room with either Bluetooth or Near Field Communication (NFC) technology. NFC is a wireless protocol that transmits data within a 4 cm distance vs Bluetooth that transmits data within 32 ft.

Taiwan has deployed NFC chip cards for accessing buildings and homes. They are named “感應卡”i.e. “induction card” in direct translation but “proximity card” in real application. With Asia’s rapid adoption of NFC, this is not surprising to see a more wide usage of NFC locks and NFC chip cards replacing actual keys. It’s more environmental friendly and cost effective.

The disadvantage of using a proximity card is that it’s still another “thing” to carry around; even though it replaces keys. In order to use our phones to unlock the door lock, an infrastructure needs to be in place to sync the “key” in the phone and a door lock. That infrastructure can be simple or complex based on the applications. For hotels, the frequency of changing a mobile key will require a more sophisticated platform to be in place. A few companies are providing the solutions; for example: Assa Abloy, HID. This falls into NFC secure access control” category.

Today, the main block for deploying a mobile key is Apple’s lock on its NFC connectivity. Newer Apple mobile devices are all equipped with NFC but access is not open to public. You can enable NFC functionality from Settings on Windows or Android phones but not iPhones. Over 57 million of Apple devices (iPhones + iPad) were sold in Q4, 2015. Without Apple’s support, the future of mobile key will not be well positioned in the mass market.

Hopefully, this post has introduced you some new knowledge and provokes some innovative thoughts. Please share with us your thoughts.

Will Wearable Help Manage Our Lives?

** This blog was originally posted at LinkedIn January 29, 2016.

Many of us count on our mobile phones to track daily tasks and make connections.  I don’t think I could operate as efficiently if I don’t have one.  During this last holiday session, I got an Apple Watch as a gift. I was not sure it would be a useful tool for me. After wearing my Apple Watch for a month, I have a new realization – wearable technology will help manage our lives even more than mobile phones.

With Apple Watch’s alerts, I stand up when I am reminded. I answer a call without having to fumble in my purse for my phone. I see texts coming in and am able to reply via voice. I work out and know exactly how many calories are burned. I can also listen to music without my phone.

My daughter brings Apple Watch usage to the next level. She uses it to control her iPhone for taking family pictures, and its workout tracker and pedometer function integrates easily into her existing health and fitness apps. I am starting to wonder why anyone would ever return to wearing a watch that ONLY tells time.

Apple watch utilizes a near field communication (NFC) chip which can also be used to make mobile payments.  This function opens up the mobile payment world to iPhone5 users even though their phones are not NFC-enabled.  However, awkwardly positioning your wrist over a reader in order to enable the payment does take some getting used to.

Apple Watch interacts with iPhone through Bluetooth which transmit data within 32 feet. Thus, this range is roughly how far you can leave your iPhone away from the Apple Watch. Although the watch loses a lot of its functionality when it gets too far from my iPhone, it is still convenient not being entirely glued to my phone.

Do you use wearables? What are your insights about them? paring
