Question

which protocol is used (other than NDEF protocol) for communication between Mifare classic 1k and nfc enabled mobile, when we raed or write indvisual blocks.

Was it helpful?

Solution

NDEF is not a communication protocol, but the message content description:

"...The NDEF specification defines a message encapsulation format to exchange information... NDEF is a lightweight, binary message format that can be used to encapsulate one or more application-defined payloads of arbitrary type and size into a single message construct. Each payload is described by a type, a length, and an optional identifier. Type identifiers may be URIs, MIME media types, or NFC-specific types..."

The protocol to read/write Mifare sectors is a proprietary see e.g. here: http://www.nxp.com/documents/data_sheet/MF1S503x.pdf
