Abstract
2.1 The problem with security in paying with chip cards is the loading of input data into an algorithm during authentication.
2.2 Separating the data blocks and switching; an additional feedback after the post-connected counters on and off at preselected times (number of clock pulses) helps to improve the security of debited and credited data.
2.3 The invention can be used for all authentication procedures where chip cards are used.
