An integral grip system for electronic circuit cards 1, such as mobile phone SIM cards, comprises moulded or cut grooves, slots or serrations 2 that improve the ease of removal and insertion of the cards in to other devices. The slots or grooves are suitable to allow a finger nail to slide the card in and out of position. A series of fine serrations (figure 3) may facilitate grip. The slot may be a complete fingernail hole slot.
