remotely (web) add/remove rfid key fobs

Projects General Guidance

Hi there.

I'm new to rfid and I understand the basic working (IF key_fob == xxx THAN).
I would like to know if its possible to define a variable (key_fob) over internet and store that value somehow permanently?

I have purchased the ID-20 reader and will install this at location A, I myself live at location B and would like to be able to add/remove key fobs (new users, lost fobs etc).

Is this possible? For example to remotely add/remove key fobs in a text file stored on an sd card and pull this data into the arduino?

Kind regards,
Sebastiaan

Yes it is.
Use a long long type of variable to store a 64 bit value. Then you can store these values in EEPROM
