What does NFC stand for?
NFC stands for “near field communication”. It is a standard for exchanging data between different devices over short distances. Its most well known application is the mobile payment, where payments are made by cell phone.
How does the NFC technology work?
The technology is based on RFID. A passive receiver (NFC tag) contains the information to be read. If the user holds the sending device (smartphone) up to this radio tag, a connection is established and the information is sent automatically.
What distinguishes NFC from other wireless technologies like Bluetooth and WLAN?
NFC has a significantly lower operating range of just a few centimeters. Another distinguishing feature is the establishment of the connection: While for Bluetooth and WLAN the connection of two devices must be established manually by the user, for NFC the communication takes place automatically due to the physical proximity of the sender and receiver.
What are the benefits of NFC?
Thanks to the short transmission paths, NFC allows for the direct and unique assignment of the sender and recipient. There is no risk of incorrect parameterization of a neighboring device. Furthermore, NFC does not need its own power supply. The energy required is created by the smartphone through induction.
How close do I have to be to the component to establish a connection?
The devices connect at a distance of 0-2 cm. Please hold the NFC tag on your smartphone as close as possible to the NFC logo on your Schmalz product.
Do I have to install an app on the smartphone?
An app is not required as long as you just wish to read data from your Schmalz product. A website with all the relevant information opens as soon as you connect your smartphone to the Schmalz product.
An app needs to be installed if you wish to configure your product using your smartphone. This function is coming soon.
Which devices from Schmalz support NFC?
Currently, NFC is supported by the vacuum and pressure switches in the VS/VSi series and the compact terminal SCTMi. The technology continues to be rolled out in additional products.
What data is transferred?
Schmalz transfers a range of information for the purpose of identifying (e.g. a serial number) and parameterizing (basic and process settings such as the display unit and switching points) its devices and for diagnostics (e.g. error messages).
Which devices/smartphones currently support NFC?
The following smartphones support NFC:
BlackBerry, Google Nexus, HTC, Huawei, LG, Motorola, Nokia, Panasonic, Samsung Galaxy, Sony Xperia. The iPhone 6 has a NFC chip, but this cannot be used by third parties. As a result, we are only offering our app for android phones for the time being.
Does NFC have to be enabled in the smartphone?
NFC is enabled differently for each manufacturer. It can typically be found in your device settings, near the WLAN settings.
Who controls the data: Input via the controller or via NFC?
Input via the controller.
The parameter values generally have equal rights. The system operator can use the controller via OI link to set whether to accept the values transmitted via NFC.
How can I find the NFC tag on my Schmalz product and on my smartphone?
The NFC chip is identified by a logo on the Schmalz product. A symbol may also be attached to the smartphone, depending on the specific manufacturer. Please read the instructions provided with your smartphone.
Can NFC be used for writing or just for reading?
Data can currently be read out from the Schmalz product via NFC. Configuration will be possible shortly.
Is internet required to use NFC?
You need an internet connection to display the website. An app, which will also allow the contents to be displayed offline, is coming soon.
