Amazon now offers push button devices for placement around your home to facilitate reordering of staple goods such as laundry detergent. They are called "Dash Buttons".
Presently, the $5 cost of the buttons is refundable upon your first order.
The idea of easy restocking is appealing, but I can't seem to find any products promoted with the Dash Button which I regularly use, so I decided to use my Android phone's near field communication (NFC) capability to duplicate the button in a more open format. I also have quite enough entities on my wifi network at home and prefer not to add several more without a good reason.
Step 1: Resources
To use NFC tags you will need to have an NFC enabled smart phone (at this point in time, that isn't an iPhone).
Head over to the App Store and download NFC Tools: https://play.google.com/store/apps/details?id=com.wakdev.nfctools.pro
Now buy your NFC tags. NOTE: not every smart phone can read every tag! Read the description carefully to check compatibility. I've had excellent results from these Topaz 512 Whiz Tags on my Samsung Note 4: http://amzn.com/B00FS4AF0S
