+Local Isracard: 8(-9?) digits
+
+From http://www.wysiwyg.co.il/Anatomy-of-CreditCard-Number-formats.asp#IsraCard-algorithm
+8-9 digits, non-LUHN validation
+
+From Erik Levinse:
+ i think it's like luhn, except instead of 212121... you put
++987654321 under the number you're validating, multiply each, and do mod 11 on
++the sum, instead of mod 10.
