The Victorinox SwissCard Classic has compact dimensions of 82 mm in length, 55 mm in width, and a height of only 4 mm, weighing just 26 g. Although specifically designed as a credit card-sized wallet, its integrated blade (letter opener) and scissors generally make it unsuitable for carry-on luggage on flights, as these items are frequently confiscated at security checkpoints. It is recommended to transport the SwissCard in checked baggage or to check with your airline beforehand regarding their current regulations.
