With this you can intercept only the first command send by the NFC chip of the card. the so called ATR. But after that you need to continue the "communication" with the chip. This is not like magnetic STRIPE, where you get all the information at once. There is a very strict standart (ISO) for communication between terminal(NFC COPIER) and CHIP (NFC Card). With this device you will get only the ATR of the card, which is totally useless. As i have said in the fist post, it is for people who know what they do
