Researchers have developed a new method for entering a pin. This is based on touch-sensitive screens on phones are found. Connection with a terminal is possible with nfc.
One of the on touch-based methods to work with so-called tactons: touch-sensitive buttons on a touch screen which, when pressed, the phone in a particular pattern vibrate. Because the tactons for each pin transaction be randomly linked to a certain vibration pattern, users need to use different buttons to touch to figure out what pattern this produces. When users feel that they have the correct order of patterns, the transaction can be confirmed.
In the second method is with a dial worked, where the user’s finger moves in a certain direction. When the correct number of vibrations is felt, the user with his finger in the other direction to move, until the correct number of vibrations is felt.
The new pin methods could be used for mobile payments, where use of phones with touch screen. For the wireless connection with the pos terminal may be made use of nfc, which already has a few applications in the payment system. The advantage of the Portuguese and Korean scientists developed techniques is that someone who is looking, the code can not reproduce. The disadvantage is that the entering of a pin code takes longer.
