I have an acccess/entry card chip I want to copy for demonstrational purposes. However I am not sure how I can find out what type of RFID reader I need to get a hold of.
Does anyone have a suggestion how I can figure out what type of chip it is and thus what type of reader I need to be able to copy it?
Possible use cases:
- Social engineering the business who owns the card or the card issuer (ex. G4S) and try find out the manufacturer is.
- Oscilloscope - Read the frequency and get a reader with the same scope.
- Dissolving the card (ex. with nail polish remover) and try find out who the manufacturer is by looking for clues on the chip or on the plastic.
