Abstract
A folding mechanism is used to authenticate purchases when making transactions using a contactless smart card. By folding the contactless card in a precise manner, the electrical resistance of the antenna circuit of the contactless card is changed by bypassing the card's built-in resistors. A user may set a folding orientation as the 'password' of the contactless card. This folding orientation determines the electrical resistance of the card necessary to authenticate a purchase.
