Question about ACS Acr122 Mifare/Nfc USB

GoToTags Windows App

ATTENTION product not compatible with the current nfc21 program, reader not recognized . Impossible to write pages 43 and 44 of the NTAG213 with the PC NFCtool software !

I use nfc21 from nfc21.de. Simple tool - there are far more complex ones.

Attention for Windows 7 you need an additional driver. You can find details under Q&A

It depends on what you want to do with the reader. If you want to program NFC chips, I could recommend you
ACR122U Made Easy (you can find it on ebay). For applications such as unlocking a PC, there are many programmes on the internet. However, I can't give you a recommendation.
