An IC card has a housing (20) which can hold a circuit board (32) at a selected level. In one card (10), the card housing comprises lower and upper halves (22, 24) that each has platform parts (114, 116, 120, 122) that engage corresponding surfaces of the circuit board. In another card (310), the housing includes housing connector parts (312, 314) with platforms (390, 392) that are received in holes (400, 402) of the circuit board. The platforms can have two or more steps to hold the circuit board assembly at a selected one of a plurality of different heights.
