hey guys, I already have a database that can add a person with the RFID card number,
I just want a little help of you guys if how can I code the rfid and when I tap the card, the RFID# of that person will be there together with the name, time and department of that person.?

Example if tag name is 00123456 (Thats my rfid card# saved to my database) if I tap the card to the RFID reader, the FORM should show that this TAG belongs to me showing my details)

Please help me, I'm doing this for almost a month so I decided to get some advise now from you guys. I only have 2 weeks left for my defense. :/ Thank you for your help. (If you can create a system that will be much better. )

This code is just for showing my rfid card# (without my details).
