I have in my the city turnstiles transport systems, which read the cards of the mifare classic 1k type nfc-a, how do I determine at what speed from the datasheet they expect the data from the map?
I think Manchester coding use but according datasheet this cards can transmit data on NRZ-L. How me know on Manchester or NRZ-L use PCD in my transport systems ?

You need to sort several things out and rephrase your questions because:
There is no Mifare Classic NFC type
There is only one speed in the Mifare Classic Datasheet
Mifare Classic uses Modified Miller coding from PCD to PICC and Manchester coding from PICC to PCD.

@piwi, i try my device-emulator 1k in transport system. My device do AUTH operation about 500 mks, but turnstile send me HALT. Why ? I read datasheet about mifare classic and in datasheet 1 ms is max AUTH operation.

There might be an error in your device-emulator, or you may have the wrong key.
May I remind you that this is a Proxmark forum, not a "my device-emulator" forum. How can you expect help for something which only you have and know?

What is error ? My device correctly read and write your proxmark3.
Key is correct, i checked the log that I'm sending At the right turnstile.
But i have problem and with proxmark3 on turnstile too after correct AUTH proxmark get HALT.

My basic question what about timing on transport system do on comand AUTH ? How fast need answer on reader request with nr,ar. I answer about 500mks after get nr,ar.
