Question and Answer:

Q: Why my phone can't read the card? The card hasn't responded?

A: Please your phone has the NFC function, that has resopn. Otherwise, you may mistakenly think the card is damaged.

Q: Can my iPhone read/copy the card?

A: Please be sure your iphone model has the NFC function. Sometimes even if the phone has authorized NFC function, even if you download other NFC software, the UID card may not respond. So I suggest you use a professional 13.56MHz programmer to write data.
