1. An entry security device, comprising:
- a validation device having at least one identification code adapted to control an electronic door lock, wherein the validation device comprises an antenna;
a power chip connected to the antenna, wherein the power chip has a control unit and a flat battery module connected to the control unit;
an encoder connected to the antenna;
an decoder connected to the power chip;
a read/write memory connected to the decoder; and
a code generator connected between the read/write memory and the encoder to open or close the electronic door lock; and
at least one contactless keycard having at least one identification code inductively read by the validation device to control the electronic door lock operation based on a match of identification codes in the contactless keycard and the validation device.

Abstract
An entry security device has a validation device adapted to control an electronic door lock and at least one contactless keycard. The contactless keycard and the validation device have the same identification codes, so that the contactless keycard sends the identification code to the validation device to check for a match with the identification codes in the validation device. A new identification code is generated by the validation device when a match is found and then is inductively sent to the contactless keycard to replace the previous identification code.
