How to use NFC in a tablet without a built-in reader

Enabling NFC applications on tablets without built-in NFC capability

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.

Using an NFC Reader as Keyboard Entry Device

Using an NFC reader to enter keystrokes generated from NFC tag scans is becoming more common. This article describes the various approaches and solutions.

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.

With iOS 12 Apple has done its part, NFC enthusiasts need to do ours

CoreNFC was updated in iOS 12 to include two new highly impactful and desired features.

New Features in CoreNFC CoreNFC was updated in iOS 12 to include two new highly impactful and desired features. For marketers wanting to leverage NFC to push content, the day has finally come where no app is required to scan an NFC tag on an iPhone. For developers wanting to use NFC to trigger actions in their apps, CoreNFC now includes background tag reading that can notify third party apps that an NFC tag has been scanned which matches a specified domain.

iPhones don't identify unique NFC tags

Apple may want to verify tag originality in iOS before enabling tag discovery or other NFC features

Since reading a tag’s unique identifier (UID) or other hardware characteristics of NFC tags cannot be done with the beta release of CoreNFC, all anti-cloning measures at the developer’s disposal are precluded. The concept of tag originality and reading a UID are related since both naive and advanced anti-cloning measures involve using it in some way. The decision to not allow developers to access the UID is discussed in this article.

iPhones won't yet automatically discover tags

By withholding certain NFC features, both Apple and iPhone users could reap rewards

Apple will be playing a far more prominent role in determining how its customers use NFC when compared to Google which takes a far more open approach. There are two areas of NFC integration Apple is choosing, so far, not to leave in the hands of app developers. The first is tag discovery and the second is anti-cloning measures used to validate that a tag is not a clone. This first article will discuss tag discovery, the next will focus on anti-cloning measures Apple may want to implement within iOS.

Using NFC to make a visual phonebook

Improving smartphone accessibility with NFC

So you’ve finally bitten the bullet, you had to get Grandma and Grandpa smartphones, and it’s really not going well. The contacts app is confusing, they don’t like using a touchscreen, and they keep accidentally calling the wrong person or opening Angry Birds when they’re trying to make a phone call. Let’s face it, smartphones are really designed to be “smart” first and phones second, which is troublesome when you grew up with phones that were just phones, and all you want your “phone” to do is make phonecalls!

The Forgotten NTAG215

A less common, but quite useful tag

Recently, there has been an uptick of interest in the NTAG215 chip due to its use in products such as Nintendo’s Amiibo figurines. The NTAG215 is a fairly uncommon tag from consumer retailers, but here at TapTrack, we’ve worked with it quite a bit in our business-to-business solutions, and have sold it as part of our tag evaluation kits for quite a while. While the rest of this post will simply describe the NTAG215 and why it’s less common than other tags, if you’re on this page simply because you’re interested in purchasing NTAG215s, please click the link below to order some:

NFC business card tag choices

What tags should you choose for your NFC business card

So you’ve decided to add NFC to your next batch of business cards and start designing them. You’ve picked the perfect subtle off-white colouring, the most tasteful thickness, an elegant font, but suddenly you’re faced with a choice of tag technology. NTAG? Ultralight? DESFire? Classic? Topaz? What do you choose? Why? If you’ve read our Tag 101 article, you probably already have some idea what tag you want, but, even if you haven’t, we’ll explain everything here.

You can't copy your NFC payment card

Thinking of copying your credit or transit card to another tag? Fortunately, you probably can't.

In the NFC space, it is quite common to hear consumers asking if it is possible for them to copy their credit card or bus pass onto another NFC card. Fortunately, for security reasons, you generally cannot do this. Most commonly available NFC tags aren’t very complicated devices. Effectively, they are small chunks of read-write memory with a radio interface tacked on. However, a we mentioned in our post on cloning hotel cards, there are also advanced cards available with the ability to perform cryptographic authentication and enciphered communication.

Presto's 24 hour delay: the theory

Cashless payments and the tyranny of CAP Theorem

It’s 2016, why does still Presto take 24 hours to update my balance? For those not in Ontario, Presto is our province-wide transit farecard system, which supports online topups, but with the caveat of requiring 24 hours for your balance to be updated. For those in Ontario, you’re probably already aware of this limitation there’s a good chance that you’ve heard some variation of the above quote. Indeed, it is 2016, so why does it take 24 hours for an online-topup?
