Defining nfc tag for access

I am working on rfid project. Is there any chance to connect smartphone and arduino in the way, i would be able to to define on smartphone(which will connect to arduino) which nfc tag is valid.

Yes there is a chance, but exactly what do you want to do?

You can send the tag's number to the arduino and store it in EEPROM for use in the validation process of an RFID system, but how are you going to know the tag's number, is it printed on the tag?
