/**
* Send raw NFC-F commands to the tag and receive the response.

- * <p>Applications must not append the SoD (length) or EoD (CRC) to the payload,
- * it will be automatically calculated.
+ * <p>Applications must not prefix the SoD (preamble and sync code)
+ * and/or append the EoD (CRC) to the payload, it will be automatically calculated.
+ *
+ * <p>A typical NFC-F frame for this method looks like:
+ * <pre>
+ * LENGTH (1 byte) --- CMD (1 byte) -- IDm (8 bytes) -- PARAMS (LENGTH - 10 bytes)
+ * </pre>
*
* <p>Use {@link #getMaxTransceiveLength} to retrieve the maximum amount of bytes
* that can be sent with {@link #transceive}.
