RFID cards: How they work

The goal of an RFID card is to send and receive data, without the necessity of contact. Simply by positioning it close to the reader, the information will be transferred to it, enabling the transaction (whichever it might be) to happen or be denied. The great advantage that they have, over the swipe cards with a magnetic field, is that they don’t get thorn by being inserted into machines. Therefore, it is very unlikely that such a card won’t work at any point in time, which is not true of magnetic cards.
