This small Python command prompt application for Windows will allow you to use ACR122U USB NFC Scanners to set-up a registration or clock-in system, based on a premade object or entrant csv list. Ensure that the NFC tags used are compatible with this scanner.

Made for Anthony Veder Rederijzaken B.V.

• Python 2.7 (Required for NFCpy)
• NFCpy 0.13.2

To run the app, you will need to replace the built in driver for the USB NFC reader with a more generic winUSB driver. You could use a tool like Zadig for this step.

Additionally, for generating an executable libusb-win32 is required. Place the libusb1.0.dll file in the root folder of the application.

Before you can use the tool, ensure that you have created a list of registration objects (such as persons) and scanned their NFC tags in advance to gain a unique 8 character identifier.

Ensure that a folder named Lists/ is present in the root folder. In this folder, place a master.csv file that containts at least a RegCode column (for the identifiers) and a check column.

Running the tool will guide you through a number of options untill the system is set to a listening state. When a tag is scanned, the input is compared to the RegCode column in master.csv and 'Yes' is entered into the check column of the newly created master_temp.csv.

Currently, stopping the listening process require scanning certain specific hard coded tag identifiers. Doing so will generate a final master_out.csv file. Starting the applicaiton and picking restart to restart the registration will use master_temp.csv as input.

Pyinstaller 3.3 can be used to generate an executable from the Python file. Please note that there are two hidden requirements:

• 'nfc.clf.acr122'
• 'pandas._libs.tslibs.timedeltas'

Running pyinstaller with the provided spec file as argument should include these requirements.

The original idea was for the application to use a database for registration management. Due to time contraints the scope had to be scaled back and the choice was made to use a csv file based system.

The application is not being actively maintained, but feel free to create pull requests if so desired.
