Abstract: A password setting method includes the following steps of: providing a lock body, which is configured with identification data; providing a reset device including a RFID, which has characteristic data; accessing the RFID to obtain the characteristic data; transmitting the characteristic data to the lock body; comparing the characteristic data and the identification data; and when the characteristic data matches the identification data, enabling a password setting function of the lock body. In addition, a password setting system and a lockset matching method and system are also disclosed.

Abstract: A wireless authentication system includes an execution end device and a control end device. When the execution end device and the control end device receive an activation signal, the execution end device generates a time related random code, and transmits the time related random code to the control end device; and the control end device generates a comparison authentication code according to the time related random code, a fixed password and a variable password. When the execution end device determines that the comparison authentication code corresponds to a set of data stored in the execution end device, the execution end device performs a predetermined operation, and the variable password is changed.

Abstract: A packaging structure to package a target includes: a tag with a first portion being adhered to the target and a second portion wrapping the target; and a film wrapping and sticking the second portion of the tag. When the film is torn, the second portion of the tag is torn as well and the tag cannot be used to re-package.

Abstract: An authenticating method includes enabling a transponder to receive a read request that contains an authentication code, enabling the transponder to extract the authentication code from the read request, enabling the transponder to generate and wirelessly transmit a reply signal that contains the authentication code, and enabling a reader to authenticate the transponder based on the authentication code contained in the reply signal. An identification system, which includes the transponder and the reader is also disclosed.

Abstract: A method for verifying authenticity of an object includes the steps of: enabling an electronic device to generate and transmit a request signal; in response to the request signal, enabling an RFID tag to generate a first authentication code based on a varying secret key, a second authentication code based on a unique identification code of the RFID tag and the varying secret key, and a third authentication code that is based on the unique identification code of the RFID tag and the first and second authentication codes, and to wirelessly transmit the third authentication code for reception by the electronic device; and enabling the electronic device to forward the third authentication code received from the RFID tag to an authenticating center for verification. A system, which includes the RFID tag, the electronic device, and the authenticating center, and which performs the method is also disclosed.
