Abstract: An e-paper identification card system including an e-paper identification card and a data updating apparatus is provided. The e-paper identification card is configured to display first image information. The data updating apparatus is electrically connected to the e-paper identification card. The data updating apparatus is configured to update the e-paper identification card according to the first image information to drive the e-paper identification card to display second image information. In addition, an e-paper identification card is also provided.

Abstract: An electronic card receiving device, including a housing, a card stand, a rotating shaft, and a contact element, is provided. The housing includes a front plate having an opening. The card stand is disposed in an inner space of the housing and includes a plate section, a connecting section, and a hook section. The connecting section is connected between the plate section and the hook section. A terminal of the hook section protrudes toward the opening. The rotating shaft is attached to the plate section and is lower than the opening. An axis of the rotating shaft is substantially parallel to the front plate. The rotating shaft rotates to drive the card stand to oscillate between an initial configuration and a card-reading configuration. The contact element is disposed on the plate section of the card stand. A method of using an electronic card receiving device is also provided.

Abstract: A connector structure includes a first connector and a second connector configured to rotatably connect the first connector. The first connector includes an insulating support, a first conductor and a second conductor. The first and second conductors respectively include first and second convex curved surfaces. The second connector includes first and second insulating housings and first and second conductive layers. The first and second insulating housings are configured to cover at least a portion of the first conductor and at least a portion of the second conductor, respectively. The first conductive layer includes a first concave curved surface matching the first convex curved surface, and is configured to be in contact with the first conductor. The second conductive layer includes a second concave curved surface matching the second convex curved surface, and is configured to be in contact with the second conductor.

Abstract: A sequential displaying method is provided. The method includes providing a display device which includes a first display area. The first display area has N first sub-areas that are arranged in sequence, wherein N is positive integer. Then, displayed images in the N first sub-areas are sequentially updated, wherein a time interval of updating the displayed images in two adjacent first sub-areas is 60/N seconds and a frequency for updating a displayed image in each of the first sub-areas is once every 60 seconds. Thus, a method for displaying time information could be improved.
