Yes i understand that but what after reading block 5 you want to go back to read block 3 again for instance (do you then have to authenticate with the sector once more?
For example (1 Card Session / Using connect() function)
Authenticate (Sector 0) -> Read Block 2 -> Authenticate (Sector 1) -> Read Block 5 -> Write Block 1 (Do i need to re-authenticate with sector 0 again)?
