I am interested in experimenting with NFC and or RFID for some projects, but I don't know what range to look for.
I know that I want to be able to both READ and WRITE to some blank tags, cards, etc. I know that I want to be able to use the cards with my phone's integrated RFID and or NFC (I own a Samsung Galaxy S5, but I am assuming most smartphones use the same range) I know that I want the ability to read data from a reasonable range, it should ideally work indoors at about 12 inches.
I need a read and write module of the specific range type, I need some cards that I can read and write to, and some tags. Do I need anything on my phone to enable the NFC? If I use cards that can only be read, what will already be on the card? Is there a specific brand, kit, or product that you recommend for my needs?
Thanks in advance.
I forgot to mention, I would like to be able to tap the reader, as well as have a card in my pocket and read it from about 12 inches away. I will be using it to store information that will let you into a room or will allow you to make changes to the whole automation system that it will be integrated into. Maybe also basic information about a person like name? Or, information about what key set is in the drawer when a tag is on a key chain.
Thanks again! I look forward to learning, so please let me know WHY you suggest anything you do.
