Abstract: An electronic ticket admission verification anti-counterfeiting system includes a ticket database for storing a ticket identifier to be downloaded and stored to a user-end device including a display screen and a sound receiving device; at least one admission determination device including a sound broadcasting device and a barcode reader for sequentially scanning a the first QR code and a second QR code displayed on the display screen. When analyzing that the first QR code is valid, the admission determination device controls the sound broadcasting device to broadcast a notification sound, and then analyzes the second QR code to determine whether to admit the user holding the user-end device. The first or second QR code is associated with the encrypted ticket identifier, and the second QR code is generated after the notification sound is received. The first QR code is different from the second QR code.

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: A control system includes a portable electronic device and a controlled device. The portable electronic device includes a user input unit, a first processing unit, and a transmitting unit. The controlled device includes a controlled module and an RFID tag. The RFID tag includes a receiving unit, a tag memory unit storing a first code, and a second processing unit. The portable electronic device generates and wirelessly transmits a first key and a control command according to user operation of the user input unit. The second processing unit of the controlled device is configured to determine, with reference to the first key received by the receiving unit and the first code, whether or not to output a control signal for controlling the controlled module to perform an action that corresponds to the control command received by the receiving unit.

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: An RFID tag includes a substrate, a chip, a conductive unit, and an antenna. The substrate is attached to an article. The chip is disposed on the substrate to partition the substrate into a first region on one side of the chip and a second region on the other side of the chip. The conductive unit is coupled electrically to the chip, and is disposed on the substrate to form a loop in cooperation with the chip. The antenna is disposed on the substrate and coupled electrically to the chip. The loop and an area of the substrate encompassed thereby are disposed in the first region, and the antenna is disposed in the second region. Removal of the substrate from the article results in a break in the conductive unit, and the chip is operable to detect the break in the conductive unit.

Abstract: An online trading method includes: configuring a marketplace server to receive a product verification request from a first user terminal and to send an authentication request to a second user terminal; configuring the second user terminal to receive the authentication request and to send a code request to a transponder that is associated with a product; configuring the transponder to receive the code request and to send a response signal that includes a unique identification (UID) code of the transponder, the second user terminal sending out the UID code of the transponder; and configuring an authentication center to receive the UID code of the transponder, to generate a verification result based on the UID code of the transponder, and to send out the verification result for notifying the first party accordingly. An online trading system for implementing the online trading method is also disclosed.
