Thank you for the video damarius.
Yup just about anything security access technology wise including RFID can be reverse engineered; always been so.
Historically too there was that reference to magic; the blink of a virtual eye; well and an easy way to explain the unexplainable in a simple language. (hundreds of years old now).
It was always just the dissemination of a knowledge base and references to whatever using whatever could be understood or not depending on the comprehension and methodologies presented or not.
It's difficult in today's world of almost instant global communications to keep a secret. Geez what is a secret?
Not too long ago recall one bank security person smitten by an employee with him showing her the intimate details of his job...then once she learned she helped herself to the bank's coffers.
Many times absolutes not understood just get discounted / discarded for another day.
Look at the in fighting (its about money anyways) going on to patent a genotype(s).
What the heck is a genotype anyways.
Mix that in too with the nefarious chameleon like virtual doppelgänger.
The OP here is:
I'm looking for a way to have a gate open whenever I (or anyone who has access) drive or walk up to it. It can currently be opened via keypad or an RF opener. I am not concerned with having a high level of security (ie: I won't be opening doors with it). I would of course like to keep it as cheap as possible but my budget is up to $300.
The assumption was to use some passive methodology and RF came to mind. Personally here using a tiny transmitter (which could and can be easily circumvented) just passing a simple 4 digit code (non encrypted).
Who would be watching anyways?
Installing da device innocuously in an automobile; not to be seen, no batteries to change or in the way in a literal sense simple and functional. Nothing fancy at all.
