While this statement may be true for certain ATM cards (including the LE155), it is certainly false in general. Every ATM card with which I have worked (IBM TW 25, IBM Charm 155, Fore HE, Iphase 5515 and Iphase 5575) all do have vendor supplied MAC addresses. (These six MAC bytes are normally appended to the 13 switch supplied bytes to comprise the 1st 19 bytes of the 20 byte ATM address in a switched environment). |
