Is this compatible with IOS NFC: MIFARE Classic 1K Chip 13.56mhz
What did MIFARE say when you asked them?
Mifare Classic 1k are not fully compatible with CoreNFC, but you can use the "compatibility mode" in NFC Tools settings to read and write standard records (NDEF).
Unfortunately, some features, like reading the memory cannot be used with this type of NFC chip.
CoreNFC does NOT support Mifare Classic 1K, so we've created the Mifare Classic Tools for iOS - MTools Lite app, which can use an external BLE Reader to read/write Mifare Classic 1K card.
It also supports reading or writing NFC tag and transportation card which has SAK under 20 and 28.
