Check out mifare-tool - it provides a write command. The following
command line works for me (16 byte write command - read write sector 4
MIFARE Standard 1K official OpenPCD RFID card):

# ./utils/mifare-tool -w 4 00112233445566770011223344556677

write(key=' ff ff ff ff ff ff',page=4): ' 00 11 22 33 44 55 66 77 00 11
22 33 44 55 66 77'(16):opening layer2 handle
running layer2 anticol
ISO14443-3A anticollision succeeded
running layer3 (ats)
we now have layer3 up and running
Mifare card available
mifare auth succeeded!

error during write (-110)

# ./utils/mifare-tool -r 4

read(key=' ff ff ff ff ff ff',page=4):opening layer2 handle
running layer2 anticol
ISO14443-3A anticollision succeeded
running layer3 (ats)
we now have layer3 up and running
Mifare card available
mifare auth succeeded!

Warmest regards,
