Abstract: A digital transaction method is applied in a user device. The user device instructs a digital transaction management server system to bind a device identification code of the user device and an order after the user device purchases with the digital transaction management server system and accordingly obtains the order. The user device generates a digital certification and a safety code, wherein the safety code varies according to a predetermined varying sequence during a predetermined time interval. After the safety code passes through an electronic verification of a service provider, the user device requests the service provider to settle an electronic transaction.

Abstract: The present invention provides a tag ablation mechanism and a tag-and-tape combination apparatus using the same, wherein a driving gear is actuated to rotate by a rotating device by way of a lever to drive a driven gear to rotate so as to ablate a tag from a bottom paper extended from a tag roll on the driven gear. In the present invention, an ablated tag is capable of being combined with a tape so that the tag attached to the tape can be adhered to a packaged object. The mechanism and apparatus of the present invention are capable of adjusting a rotating arc length so as to handle various tags with different sizes and lengths and to complete tag ablation and tag-and-tape combination in each driving operation.
