How to use the EMV Credit Card Reading SDK with the µFR Nano Online

How to use the EMV Credit Card Reading SDK with the µFR Nano Online Although the device delivers the raw read data to the remote server, it does not support EMV encryption on its own. This means that without deploying any intermediary software solution that applies such encryption, the device cannot transfer the encrypted credit card data to the web-based system. In order to test the device’s credit card reading, you can use some of the desktop SDK projects from the list of SDKs below: Credit card reading software SDK C++ Credit card reading software SDK C# Credit card reading software SDK C  Credit card reading software SDK Java Credit card reading software SDK WPF USB-connected device requirements This device can be used with the desktop software in the same way as any other µFR Series reader without network support if you plug it into the PC’s USB port. You only need to have the FTDI drivers installed on your machine in order to use the software. Please check the FTDI drivers installation instructions at https://www.d-logic.com/knowledge_base-tag/ftdi-drivers/.

µFR Reader Writer on macOS – FTDI drivers and communication permissions tips

µFR Reader Writer on macOS FTDI drivers and communication permissions tips *NOTICE: Applicable only to old macOS versions and legacy µFR devices. Do not use for the µFR Zero series and recent macOS releases! macOS has a bit different structure than Linux so communication with the reader cannot be enabled with a simple script available for Linux users. Enabling the communication between the software and the USB-connected reader varies depending on the macOS version. The OS versions from Mavericks (version 10.9) and above already have the AppleUSBFTDI driver. The interface is matched to the FTDI kext, which in turn creates a BSD serial port for use at the application layer. The application opens the serial port to communicate with the hardware. On the other hand, the USB-connected µFR devices implement user client drivers to communicate directly with the device from the user space (FTDI D2XX Driver). Therefore, the presence of the AppleUSBFTDI kext might affect communication with the software. Software applications may fail to open a connection with the hardware because IOKit already has matched the AppleUSBFTDI driver to the device. The solution in this instance is to unload the AppleUSBFTDI drivers before installing the FTDI D2XX. You may find...

How to access the µFR Nano Online configuration panel after setting the 2.4GHz BLE HID mode?

How to access the µFR Nano Online configuration panel after setting the 2.4GHz Low Energy HID mode? When µFR Nano Online works in a 2.4GHz Low Energy HID mode and is paired with the host device (PC, phone), its Wi-Fi access point is turned off to save power. To access the device frontend configuration panel, you need to disable (unpair) the 2.4GHz Low Energy connection on the host device first. After that, the access point with the Wi-Fi SSID named the serial number of the device (i.e. ON1XXXXX) will be turned on. Finally, connect to this Wi-Fi access point and access the configuration panel by typing the IP address 192.168.4.1 into your browser. Alternatively, you can reset the device to Wi-Fi Slave mode by resetting the device to factory settings using the uFR Online Flasher tool.

Running Python SDK/software on macOS

For Python software examples, we suggest you use any Python 3.x.x version. If you don’t have the right Python version installed, use the following command line to install a new version: brew install python Now simply run our source code software example with the command: python3 file_name.py Please have in mind that our Python SDK structure has only one executable .py file (main file) and that one imports all other files as modules. For example, the NDEF Python SDK console uses ndef_example.py as the main file, so the software is executed with the following command: python3 ndef_example.py To make sure which file is the main executable file, you can simply check the source code of the *.py files and look for the one that has a ReaderOpen/ReaderOpenEx function calls.   NOTE: This test was performed with Python 3.7.2 so and included the following SDK:     https://code.d-logic.com/nfc-rfid-reader-sdk/ufr-ndef-examples-python-console     https://code.d-logic.com/nfc-rfid-reader-sdk/ufr-mf-examples-c
