5. Opsætningsvejledning
Follow these steps to set up your ACR122U reader:
- Driver installation:
- Insert the provided Driver U-Disk into your computer's USB port.
- Locate and run the appropriate driver installer for your operating system (e.g., Windows). Ensure your system has Windows Installer 2.0 or later.
- Follow the on-screen instructions to complete the driver installation. If the U-Disk is unreadable, drivers can often be downloaded directly from the manufacturer's support webwebsted.
- Tilslut enheden:
- Connect the ACR122U reader to an available USB 2.0 port on your computer.
- The system should recognize the device after driver installation.
- CIE 3.0 Functionality (for Italian users):
- For CIE 3.0 functionality, the NFC driver must be installed first.
- Download and install the appropriate CIE ID middleware from the official Italian government webwebsted.
- After installing both the NFC driver and CIE middleware, open the CIE program and place your CIE card on the reader's NFC area. Follow the program's instructions to complete the process.

6. Betjeningsvejledning
The ACR122U functions as a reader and writer for various smart cards and NFC tags. Its operation largely depends on the software application you are using.
6.1 Basic Read/Write Operations
- Softwarevalg: Choose a compatible smart card or NFC application. For general NFC tag reading/writing, applications like NFC Tools are often recommended for their ease of use. For more advanced or specific applications (e.g., programming custom cards), you may need specialized software or development kits.
- Place Card/Tag: Position the smart card or NFC tag directly on the surface of the ACR122U reader. Ensure it is within the reading range (up to 50 mm).
- Perform Operation: Use your chosen software to initiate read or write operations. The software will communicate with the reader to interact with the card/tag.
6.2 Advanced Usage and Programming
The ACR122U is often utilized for secondary development and programming. Users intending to program or develop applications with this reader should have familiarity with programming concepts and software development. The included Driver U-Disk provides SDKs (Software Development Kits) and demo applications to assist in this process.
The blank UID cards and key fobs included in the package are suitable for secondary development and testing purposes.
