Frequently Asked Questions

This area contains the questions our customer ask us most frequently. Maybe your question is also in this list and can be answered right away...

What is the difference between RFID and NFC?

Often these two terms are used identically, even if they are actually different things. RFID (radio frequency identification) is the generic term for the entire technology, i.e. passive transponders and corresponding read/write devices. NFC (Nearfield Communication) is based on RFID, but describes a sub-form. Here, the format of the data is also defined and the type of communication. So all NFC products are also RFID products, but not vice versa.

If you are looking for a device to read and write data in an industrial NFC-compatible way, our QuasarMF is the right product for you.

Why does the PC not find a USB-driver for my metraTec product?

Normally the driver should install itself automatically via Windows Update under Windows 8 / 10 (sometimes it takes a while). This requires an internet connection.

Otherwise, please disconnect the device once and download the driver from http://www.ftdichip.com/Drivers/CDM/CDM21226_Setup.zip and follow the instructions. If this also does not solve your problem, please contact our support team.

What is the default IP and password of a metraTec Ethernet device?

The default IP address of all metraTec devices is If your host device (laptop, PC, etc.) happens to be in the same subnet (i.e. it also has an address that starts with 192.168.2.x) you can use the internal webserver on port 80 to change the IP address.

If you are in a different subnet, use our TUC Configuration Manager to change the IP to something else even across subnet borders.

The default login for our devices is "admin"

The default password for our devices is "tucadmin".
