BLANK 125KHZ PROXIMITY CARDS
These Blank Proximity cards are simply that, they’re blank proximity cards. Proximity technology operates on 125kHz frequency and is ideal for access control solutions. Proximity cards are powered by resonant energy transfer and have a range of 0-3 inches in most instances. The card reader presents a field that excites the coil and charges the capacitor, which in turn energizes and powers the IC. The IC then transmits the card number via the coil to the card reader.
