Hi,

I need to save the NFC reading result to a file or database and append timestamp and after continue waiting for a reading.

Should be straightforward. Pick where and write code.

Thank's crjeder,

Now i'm using raspbian. I'm not sure what language can I choose... I'm confortable using bash script. It's possible?

Finally, mysql or mariadb as db it's ok. If it's easy save the reading to a file, it's ok too, after i know how to export to a db.

Thank's again

UNIX has a very powerful concept named "pipes" which is was you need. You can read more about it e. g. here: Linux Tutorial - 11. Learn Piping and Redirection

Basically to redirect the output of "nfc-read" to a file you do:

nfc-read > file

If you want to redirect to an other program do:

nfc-read | db-import

I already know about Pipes, but you give me a great idea. Thank's!

By now I'm using this bash script...

#!/bin/bash
explorenfc-basic > temp_file.txt
input=`grep UID temp_file.txt | cut -d " " -f 3`
mplayer beep-07.wav
mysql -u MYSQL_USERNAME -pMYSQL_PASSWORD -e "INSERT INTO table_name (field1,field2,field3) VALUES (NULL,'$input',CURRENT_TIMESTAMP)" database_name

Thank's again!
