ABSTRACT:
A fool-proof mechanism for memory card is presented, in which an asymmetrically configured insertion end of a memory card is provided to ensure that no incorrect insertion of the memory card will be done; and a length or height gradient of circuit's contact produced according to an asymmetric arcuate or curved alignment of a plurality of circuit's contacts will create a contact time difference between contacts of different circuit's contacts with corresponding contact terminals for application in design of specific circuits.
