Readers Wiegand or Clock & DataSwipe Cards• Mag Swipe (Hotels – old credit cards)• A plastic card with a magnetic strip containing encoded data that is read by passingthe card through a usually slotted electronic deviceProximity (125kHz)• Contactless (Access Control)• Within the Proximity card an IC, capacitor, and coil are connected in parallel. The cardreader presents a field that excites the coil and charges the capacitor, which in turnenergizes and powers the IC. The IC then transmits the card number via the coil to thecard reader. The card readers communicate in Wiegand Protocol that consists of a data 0and a data 1 circuit.SMART 13.56mHz (MiFare / iClass / Legic / Indala / Deister etc)• Contactless (Access control / Cashless Vending)— Card• Contact― Chip and PIN― The Contactless chip communicates with the card reader through RFID induction technology.Like smart cards with contacts, contactless cards do not have a battery. The card readerpresents a field that excites the coil and charges the capacitor, which in turn energizes andpowers the card’s electronics. Data can be read and written.7Pulse Stretchers RDR-INT-PULSESTR• Allows non GTL format readers to be used on an IDC• Symptoms:• One read in 5 / 10 reads of a valid card will not allow access• Comms - View - Line Controller - Line - Box – DUMP• Same number of bits should be displayed each time the same card is presented• For each IDC only 1 x RDR-INT-PULSESTR is required73
