The basic RFID system is a simple transponder. All it does is enables the chip to transmit a number when scanned. That number is essentially an indexing string of data which contains no personal information. Out of the context of the process of the read - the number has no significance. Plus - that context has deeply embedded encryption algorithms based on time, location and date - which are called "one way ciphers". Credit cards can store other information on the magnetic strip - including your name but never a PIN - some contain only a number.
