Embodiment Construction

[0052] Figure 1 shows a typical card used to store information, especially confidential information inf. In this embodiment, the card is a smart card CAR. For example, such a smart card CAR has the physical size of a typical credit card. The smart card CAR has a small keyboard KEP located on it. The keypad KEP is composed of an input element such as a key KEY for inputting numbers or characters for inputting a PIN code. The smart card CAR displays the PIN code PIN and possibly text information and digital results on its display DSP, for example, an LCD display. In addition, the smart card CAR also has a power source such as a battery (see Figure 2).

[0053] In addition, the smart card CAR has an interface device such as an electrical interface board INT, which provides electrical contact points between the card reader (not shown in FIG. 1) and the circuit of the smart card CAR.

[0054] When the smart card CAR is inserted into the slot of the card reader, the electrical interface...

Abstract

A card (CAR), for example, for storing confidential information (inf) and / or performing security actions, the card (CAR) comprising input elements (Tl, T2) for entering a PIN code, wherein a specific unambiguous value is assigned to each input element (Tl, T2), and wherein the card (CAR) comprises at least two and maximally nine of said input elements (Tl, T2).

Description

Technical field [0001] The present invention relates to a card including an input element for inputting a PIN code. [0002] The invention also relates to a method of entering a PIN code into the card. [0003] The invention also relates to a card reader. Background technique [0004] This type of card is usually used to store information, especially confidential information, and / or generate information after a PIN code (personal identification number) is correctly entered into the card. Alternatively or in addition, such a card can also be used to perform security functions, such as generating a TAN code (transaction number). Only after the PIN code is correctly entered into the card, or when the information is generated after the PIN code is correctly entered (preferably in the card), is it allowed (for at least a predetermined period of time) to access the confidential information stored on the card . [0005] As mentioned above, after the correct PIN code is entered, a securi...
