The short answer is, it depends on how much time and money you want to spend. The way most RFID security systems work is by just reading the serial number on your token, and then sending that off to a computer somewhere that will say yes this serial belongs to a resident or no it doesn't. This also means that cloning a card is just copying the token's serial number to another token.
The is complicated because:
Even if you know the chip's frequency (e.g 125khz), there are a ton of different chips used in...

SkimProt – Protective sticker against bank card fraud
RFID skimming or digital pickpocketing is the wireless interception of information from RFID chip-based debit, credit and ID cards and other documents, such as passports.
The purpose of RFID skimming may be simple theft of funds or more complex identity theft.
Anyone with a NFC reader/POS terminal (with an additional antenna) can pick up the information from your NFC bank card and without your knowledge complete a transaction for the maximum amount of money, allowed to be withdrawn from a NFC card without a PIN. In Bulgaria this is 25 bgn.
