Description

Title: ULTRA SLIM CARD INCORPORATING A USB DEVICE

TECHNICAL FIELD

This patent application relates to the wallet-sized plastic card like a credit card or membership card that incorporates a USB (Universal Serial Bus) device and/or magnetic strip and/or a smart chip and/or NFC (Near field communication) device.

BACKGROUND A USB card is already commercially available, and it consists of a card body which is a plastic body and a USD device connected with the card body. Figures 1A-1E depict several samples of the existing USB cards. A common feature of these USB cards is that the card body has a cut-out portion accommodating a USB device.

The USB device can be securely attached to the card body or it ca be pivotally/slidably connected to the card body, depending on the aesthetic and design requirements. Figure IE also shows a USB card connecting to a USB port of a computer.

The prevailing manufacturing technology of the existing USB card is injection molding of ABS to form the card body. Patterns and labels are direct printed or adhered onto the plastic surface of the card body. Patterns and information cannot be printed on the ABS surface of the body by offset printing; labels bonded to the surface are subject to peeling up.

Due to an overall thickness of at least 2.5mm, the ABS USB card cannot be embossed. Also magnetic strips or smart chips cannot be embedded into the body, due to the potential overall thickness makes the card non-operates with a regular card reader. PVC card is also well known as it is normally used as credit cards or membership cards. A PVC card can be applied to more manufacturing technologies, such as embossing, offset printing. A PVC card may also embed a smart chip and/or magnetic strip and/or NFC chip. See figure 2. Even embedded with a smart chip, a magnetic strip and an NFC chip, a PVC card can still swipe across a card reader, see figure 3. A web key is recently-developed tiny electronic device that can be connected to any reader equipped with USB or mini USB port, such as computers, mobile phones, smart phones, tablets, etc.. Once such a connection is established, an internet browser will be pop-up, and a predetermined web page will be shown in the display. As a web key contains no memory therein, it usually has a small size, compared with other storage devices, like USB memory devices. Detailed descriptions of a web key incorporated slim card can be found in the Hong Kong short-term patent Publication No. 1146194A.

DESCRIPTIONS OF EMBODIMENTS

Referring to figure 4, the figure which demonstrates an existing PVC card with a USB storage, the card body is cut out to accommodate a smart chip. This card (commercialized by www.plug-up.com) is similar to a USB storage that can be directly connected to the internet using the USB port without a card reader or any hardware drive software. The USB storage may be embodied as a web key. The USB storage and its cover are attached to the card body by breakable joints along its edges. Users have to break the joints to get out the USB storage and insert the same into a USB port afterwards. The disadvantages are that once the USB storage is removed from the card body, it can not link to the body again.

Figure 5 depicts samples of the ultra slim card of an embodiment of the present invention. The ultra slim card comprises a card body formed of multiple PVC layers by lamination, an attachment by which a USB device can slide in and out of the card body. Figure 5 illustrates the USB device is completely received in the card body and is slid out of the card body.

Figure 6 shows more details of the ultra slim card incorporating a USB device. In this embodiment, a sandwich type card consisting of three layers are explained. Other numbers of layers are also within the scope of this invention. Each layer is made of PVC and forms the card body by lamination. A middle layer 1 accommodating a USB device 2 has a cut-out portion, and the cut-out portion is provided with a groove 3 along both of its edges, so that the USB device 2 can freely slide within the groove 3.

To restrict the extent of the sliding of the USB device 2, the groove 3 is configured with two recesses 4 along its length. The recesses 4 can engage with a projection 5 at an end of the USB device 2 which extends laterally from its side. The projection 5 contacts with the groove 3. Once the projection 5 engages with a recess 4, the USB device 2 can be secured in that position. Each recess 4 defines a sliding position of the USB device 2. Although the embodiment of figure 6 shows recesses 4 are farmed on both sides of the groove 3 and both sides of the USD device 2 have a projections 5, disposing the recesses and projection on one side only is also possible. If only one sliding position which defines the most extent that the USB device can slide out is preferred, the groove 3 can be configured with only one recess or one pair of recesses on both sides of the groove 3.

The USB device 2 is formed as a frame 7 carrying an electronic chip 8 in a cavity 9 thereof. The projection 5 extends laterally from the sides of the frame 7. Due to the larger thickness of the electronic chip 8 located at the connecting end of the USB device 2, the USB device 2 has a maximal thickness of 2.3 mm at the connecting end (the electronic chip 8), and the frame 7 overall is less than 1.1 mm in thickness.

The embodiment of figure 6 shows the middle layer 1 has a thickness not less than that of the frame 7. However, if a thicker frame is applied, more layers are required to form the cut-out portion so as to accommodate the USB device.

In an alternative embodiment, the middle layer 1 has a thickness at least the same as the frame 7. No groove is provided whilst the USB device 2 can still slide in the cut-out portion. However, a stop 6 is formed as a protrusion from one or both sides of the cut-out portion. Once the projection 5 of the USB device 2 contacts the stop 6, the USB device 2 cannot slide outward any further.

The USB device can be made by chip-on-board (COB) or surface mounted technology (SMT) and with a maximal thickness of 1.2mm. A known method to prepare a USB data storage with such a small thickness is taught in US 201110292586 Al, the prior art which discloses a storage device of a package of COB.

Except the connecting end of the USB device 2, the ultra slim card is less than 1.1mm in thickness. Such a slim dimension allows to be swiped across a POS machine. Contrary to that, the existing ABS USB card cannot swipe across a POS machine.

In a preferred embodiment which is similar to figure 6, one of the PVC layers making the card body has a hollow area 13 fitting a NFC (near field communication) chip 12. This permits the card to communicate with external reader wirelessly, as shown in figure 7.

Still referring to figure 7, a folding function of the frame is described. Since the frame 7 is very slim with a thickness of less than 1.1 mm and some adapting ports of external devices are larger than that dimension, the connecting end of the frame 7 can be folded up by the hinge. The connecting end of the frame 7 may have a folding line 11 with a reduced thickness as so to act as a hinge, and a folding piece 10 may be folded along the folding line 11 and abut against the frame 7. In this embodiment, the electronic chip 10 is carried by a cavity in the folding piece 10.

In another embodiment, the frame 7 is configured as that in figure 6, but the folding piece lO.is connected to a connecting member 12 by the folding line 11. The connecting member 12 is attached to the frame 7 by adhesives.

As illustrated in figure 8, the ultra slim card is configured as a credit card or membership card. A magnetic tape is embedded into the card body or adhered onto the surface of the body. This card has an embedded microchip. Preferably, the card may have a chip therein to communicate with an external device wirelessly (e.g. an NFC chip). All of the magnetic tape, microchip and wireless chip can store data. Once the card is inserted into a reader, users can access to the data and change the same if necessary.

Still referring to figure 8, the card is embossed to present personal information, say cardholder’s name and account numbers. ABS cards cannot be processed by embossing. Surfaces of the card body can be decorated with card issuing company’s logo by offset printing.

As can be seen from the above disclosure the ultra slim card is advantageous comparing with the existing ABS USB card and the PVC card with USB function. Specifically, the ultra slim card can be made with less that 1.1mm thickness at a high quality of surface printing. The ultra slim card can also incorporate with magnetic strip and/or smart chips; the card body can be embossed for personalization.

It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
