NFC implant received – and now?
Here we explain how to describe your NFC implant correctly in order to use it optimally for everyday life. All these possibilities are also applicable for normal NFC tags. We recommend the app “NFC Tools” to get started, because it is easy to use, you don’t need any previous knowledge and it supports many free functions.
What you should know about the NFC implant beforehand
Read NFC implant
First, your smartphone needs to get acquainted with your NFC implant. This way you ensure that the functions selected and configured later are also compatible and work properly. The RFID spiral that is essentially responsible for reception is located in the batteries of smartphones. Since these have different shapes, it may take time to determine the correct point and angle. With this reader tool, you can also check whether your purchased NFC lock, car lock or similar lock is working. Your implant supports. The exact NFC type can be found in the data sheet of many devices. If you still have any questions, please do not hesitate to contact us.
In the Writing subsection, we get down to the nitty-gritty. Different data sets can be added and combined from a pool of functions. But more about that in the next step. The Pro version is suitable for NFC users who want to copy and manage many data sets, so less interesting for the implant user. Immediately below is the trigger for the write function with information about the size of the data set being written. Keep in mind that the new data set is always exchanged for the old one. In turn, a data set can completely occupy the memory. You will quickly get a feeling that the 888+ bytes (unformat) are more than sufficient. Since many functions can be combined, it makes sense here to set the priorities by shifting them up or down. However, this causes the functions below to be partially ignored, as Android finds them to be of little use or some functions to be contradictory. The proof of the pudding is in the eating.
Available NFC functions
All “single” ways to describe his NFC implant. Why individually? In the Tasks section you will also find pre-programmed combinations. For example, when you are sitting in the car, you not only want your smartphone to connect to the Bluetooth handsfree, but also want the wifi to be turned off to save power for navigation. But more about that later.
Now select the desired function and follow the tutorial below. If you get stuck at any point, support will be happy to help. email@example.com
Describe NFC implant
If you have now successfully added a function to the data set using the tutorial below, you can write the data set to the NFC implant. To do this, select “Write / X bytes”. Now a window will open asking you to touch the tag. The same principle applies here as for the readout. It can take some time to find the right spot on your smartphone.
The implant only reacts the second or third time? This can be quite normal and has several causes. Firstly, the chipset we use is a Mifare Ultralight and is therefore just large enough to evaluate data at this high frequency in the latest NFC technology. Larger chipsets are not suitable as implants. The other cause is people and smartphones. We are accustomed by ever faster processors that a touch causes a reaction in fractions of a second. After a little practice, hardly any repetition will be necessary.
Share social media data
“Do you have Istagram?” or “Ad me on Facebook!” is something you hear almost daily. Especially with new acquaintances, it is now common to ask for a social profile instead of mobile number. Often it fails at frequently represented names or very neutral profile photo to filter out the right contact. This can be remedied with an NFC implant. Select the desired platform. Then enter your user name. If you don’t know your profile name, just log in to Facebook or co. using your browser and copy the name or ID into the appropriate field. If your opponent has the preferred social app, your profile will open automatically.
Open a specific file with one touch. This can be a photo or an .mp3 file. If you do not know the exact path, you can select it manually by clicking the arrow next to the text input. Keep in mind that if you move the file to another folder on the smartphone, you have to adjust the path.
Here you can create a sample email in no time at all, which then opens automatically when you touch the NFC tag. The “send” button, however, must still be clicked manually. This is also intentional, because you can still decide from which email address the pattern message should be sent. With a character length of 100 plus a 12-character subject line, we need a storage space of 148 bytes.
Problems describing the NFC implant
The smartphone does not respond to the implant
If you exclude the typical causes, but I still want to mention once:
- NFC is not enabled
- The smartphone does not support NFC
- The avoidable NFC tag is not an NFC tag
- The repurchased non-original battery does not support NFC
in fact, only the defect remains. Often it is due to the NFC tag, since these chipsets are produced in large quantities, it can happen that a tag was produced incorrectly. With our NFC implants, this can usually be ruled out because we subject each day to strict controls before it is shipped. If the NFC implant is still not found, please contact support.
A spelling mistake occurs
A write error occurs when the smartphone has recognized the NFC tag, but there are problems with the labeling. If you hold your implant to the device before the write process is complete or the NFC tag is simply not writable, this error message occurs. To determine this, switch the tab to “read” and check after the scan whether the tag can also be written. If this is a 125Khz tag, it cannot be written to. If the app displays a “MIFARE Classic®” format, these formats are to be described, however MIFARE Classic® is not supported by most cell phones.
Our NFC implants can be equipped with a 3DES encryption algorithm as it is based on a MIFARE NTAG216® technology. Depending on the execution of the tag, even a password can be set. If you do not have these write permissions or enter them incorrectly, you will get exactly this message.
