Sept 15, 2018 The all-in-one nature and large touch screens offered by tablets at very reasonable price points make them a very appealing option for many of uses - displaying product information microsites, powering brand activation points, and simply being the brains behind kiosks of all varieties. Unfortunately, while these tablets offer many connectivity options and plenty of sensors, one thing they often forgo is NFC capability. Further, even if the tablet does have NFC, using it often requires the tag to be tapped on the back of the tablet, which is highly impractical in most NFC applications.

Sept 24, 2018 Using an NFC Reader as Keyboard Entry Device Over the past couple of years, we’ve helped customers achieve keystroke entry from an NFC tag. Barcode scanners have for years come with this as a standard feature yet NFC readers for the most part don’t come with this capability in a built in or plug and play fashion. In this article we’re going to discuss this topic and the various solutions to this problem.

Dec 8, 2016 Previously, we showed how you can easily start developing NFC applications on NodeJS with a Tappy device using the TappyTcmpJs library. While that project was very short, much of the code we had to write was boilerplate for composing commands and making sense of the Tappy’s responses. This is necessary in order to take advantage of the full power of the Tappy family of NFC readers with all of their advanced commands and any custom commands we may develop for your use, but in a lot of applications, you only really need to detect tag UIDs as well as read and write NDEF messages.

Even after a decade since the term Near Field Communication (NFC) was introduced, I still have clients, advisors and prospective customers ask me if NFC can be used to track physical location or operate at multiple meter ranges. Although NFC is considered a subset of Radio Frequency Identification (RFID) in the hierarchy of electrical engineering applications, there are several distinctions that make them suitable to different applications. NFC is designed to realize a fundamentally different set of features than those supported by traditional UHF RFID.
