Setting up an IC card reader (macOS)

You can use an NTT Communications IC card reader in macOS.
Make sure to read the following notes before you do so.


  • USB power supply problems on Mac computers can prevent card readers from recognizing cards correctly.
    If the issues persist when you connect directly to the USB port on your machine, use a self-powered USB hub.
  • As the Tokyo Institute of Technology has yet to verify the operability of the Request System for Goods, etc.,on macOS, you may not be able to get help with issues that occur as a result of a version update or other similar procedures.
  • Please use certain IC card readers which are found to be operated, ACR39-NTTCom and ACR1251CL-NTTCom.
