Frequently Asked Questions
Where are you based and how long will shipping take?
We’re based in Sydney Australia and it is our policy to get everything shipped out within 24 hours on business days.
From then onwards, our team of highly trained kangaroos will carry your order in their pouch. If you’re based within Australia, you should receive your order within 1-6 business days. Orders are usually delivered to metropolitan areas within 1-3 business days.
International shipping takes between 3-12 business days.
There are indeed a few differences between our Mifare, NTAG213 and Topaz 512 Tags.
Our Mifare NFC tags have the largest memory capacity amongst our product range (716 bytes of writeable memory). They sport our Android edition theme and are constructed in exactly the same way as our NTAG203 and Topaz 512 tags (30mm in diameter, made from PVC with our class leading 3M adhesive back). However, these tags are not compatible with all devices.
Our NTAG213 tags are our next step up. These tags hold 137 bytes of writeable information and are perfect for regular NFC use. They come in our gorgeous ‘tap here’ design and are compatible with all NFC devices. These tags also feature a quick read/write time.
Our Topaz 512 NFC tags sport our Android edition design and can hold up to 450 bytes of writeable information. These tags are our newest offering and are compatible with all NFC devices.
Our NTAG216 NFC tags are our latest offering. These tags sport a brand new design and come with a 888 bytes of writeable memory. These tags, like the NTAG213 and Topaz 512 tags, are compatible with all NFC enabled devices.
Erasing your NFC tags is pretty straight forward and shouldn’t take more than a few seconds.
The option to erase NFC tags often comes embedded in your standard NFC writer app. For this demonstration, we’re going to use the NFC Tools App. If you don’t have it, you can grab it here.
Open up the app and select 'Other' (available at the top of the screen).
Select 'Erase tag’.
Now simply hold your NFC tag against the back of your NFC-enabled smartphone where your NFC receiver is located.
All done! Congratulations on formatting your NFC tag!
If you were unable to format your NFC tag, the tag might be locked.
They most certainly are!
When writing to the NFC tags, be sure not to ‘lock’ them via your NFC app. Once tags are locked, they cannot be unlocked. This is an inbuilt security feature that is designed to prevent other people from altering the information stored on your NFC tags.
If the NFC tags are not locked, you will be able to continuously erase and write to them.
We recommend that WhizTags be stored in an area where the maximum temperature does not exceed 70º Celsius (158º Fahrenheit). Anything hotter than this will result in the PVC becoming temporarily soft, however the functionality of the NFC chips inside the tags will remain unaffected.
The NFC chips inside the NFC tags will survive temperatures in excess of 175º Celsius (347º Fahrenheit). In fact, each NFC tag is laminated at this temperature with the NFC chip already inside.
So the NFC tags aren’t working and you’re just about ready to pull out your hair. Don’t stress! There are three common reasons behind this:
1) Please double check that you’re not using the NFC tags against a metal surface. As mentioned in our product listings, unfortunately WhizTags are not compatible with metal surfaces.
2) Please also make sure that you’ve located the NFC receiver on your smart phone. This is usually located somewhere along the back of the phone. To find the NFC receiver, first enable NFC on your smart phone and slowly run the NFC tag along the back of the phone. You’ll have found the NFC receiver once you hear the NFC beep. Tapping your NFC tag against this area will allow you to seamlessly use your new NFC tags.
3) Please make sure that your phone is not locked (i.e. the lock screen is not activated). This is a safety feature that’s embedded into NFC technology which is designed to prevent strangers from using NFC to maliciously interacting with your device without your knowledge.
If neither of these steps work then you may need to erase your NFC tag. Our NFC tags already come completely erased, but in some rare situations you may need to redo this process yourself. Luckily it’s really straight forward and only takes a few minutes.
Firstly download “NFC Tools” from the Play Store (https://play.google.com/store/apps/details?id=com.wakdev.wdnfc&hl=en).
Open the application and select “Other” (at the top of the screen). Select ‘Erase tag’ and then place an NFC tag at the back of the phone. This should erase the tag. After this happens, try rewriting the tag using the NFC Task Launcher application.
Please double check that your device is listed as a compatible device with our NFC tags. You can find the list of compatible devices in our product descriptions.
This is an error that is normally associated with Mifare NFC tags. As a general rule of thumb, our NTAG213, NTAG216 and Topaz 512 NFC tags are compatible with all NFC-enabled smartphones.
