Abstract: An anti-counterfeit device with dynamic barcodes is disclosed. An anti-counterfeit system with dynamic barcodes provides an anti-counterfeit mechanism when a user uses an electronic value barcode. The anti-counterfeit device includes a barcode generator module, an anti-counterfeit generator module and a combination module. The barcode generator module generates electronic barcodes that can be read directly by a barcode reader. The anti-counterfeit generator module generates dynamic anti-counterfeit labels with dynamic exchange information varying in time. The combination module generates anti-counterfeit barcodes by combining the electronic barcodes and the dynamic anti-counterfeit labels. The dynamic anti-counterfeit labels are visible, and are used for enhancing the anti-counterfeit capability of the electronic barcodes. Moreover, the electronic barcode with the dynamic anti-counterfeit labels can be read directly and correctly by the barcode reader without illuminant interference. Therefore, whether the electronic barcodes are forged barcodes is determined by observing the dynamic changes of the dynamic anti-counterfeit labels.
