An example multifunctional card holder comprises: a transparent screen that is attached to a back piece, a spring inside a card holding space between the transparent screen and the back piece, where in the spring connects to the back piece so as to hold one or more cards inside the card holding space by pushing one or more cards against the transparent screen, wherein the spring in substantially straight; the back piece; and a clip attached to the back piece outside the card holding space, wherein the clip includes a first connection opening located substantially at center of upper portion of the clip and is configured to mechanically connect the card holder to an item of a user; and wherein the clip includes a second strip shape opening located at substantially center of the clip.

An RFID protection and low frequency signal isolation sheet for a folding wallet has a metal interlayer. Upper surface and the lower surface of the metal interlayer are covered with protective layers to form an RFID protection folding sheet. The RFID protection folding sheet is inserted into a cash compartment of a folding wallet. The RFID protection folding sheet has a length slightly less than that of the cash compartment. The RFID protection folding sheet has a width slightly less than a depth of the cash compartment. The RFID protection folding sheet is placed into the cash compartment and located at an inner edge close to an outer layer of the folding wallet. By folding the folding wallet, the RFID protection folding sheet forms the peripheral protection of the folding wallet, and the data of the electronic chips (RFID) of cards inside the folding wallet is blocked.

The disclosure includes a wallet comprising an open-sided shell, a flexible member coupled to the open-sided shell, and a pull tab coupled to the external surface of the flexible member. The disclosure also includes a wallet comprising an open-sided shell, a flexible member coupled to the open-sided shell, a stretchable band configured to wrap around the open-sided shell and the flexible member, and a radio frequency identification (RFID) protection plate coupled to the open-sided shell. In some embodiments, the RFID protection plate is configured to securably couple at least one personal card between the RFID protection plate and the open-sided shell. The disclosure includes a wallet comprising an open-sided shell, a first protruding portion coupled to the open-sided shell, and a second protruding portion coupled to the open-sided shell.

A contactless card divider includes a body having a front side and back side and a width therebetween, and a waveguide disposed between the front and back sides. The waveguide is configured to guide a first electromagnetic wave emitted toward the front side through the width of the body to the back side with a first predetermined delay.

System and method of storing cards for ease of carrying and access by a user. The system, which may be a wallet, may include a sleeve or band that tightly holds or maintains a card or plurality of cards. The sleeve may have an opening at the top and at the bottom to allow for cards to be positioned within the sleeve. A pull-strap may be coupled to the sleeve and weave through the sleeve in an S-shape to create a first pocket for cards and a second pocket for cards. The pull-strap may pass through a guide in the body of the sleeve that can be pulled or actuated to allow for easy retrieval of the cards from the pockets. The pull-strap and cards can be easily retracted within the sleeve with a single hand of a user.

A strap is provided which may be attached to a rear portion of the casing of a cell phone obviating the need for a user to wrap her/his hand around the phone. A plurality of embodiments depict different quick-change ways of attaching the strap to the casing or directly to the back of a cell phone. A quick-removal holster is also described, as is a belt clip which engages the strap without the need to grasp the phone casing. The case is provided with a compartment for 2-3 credit card-sized items. A retractable kick stand forms a hood over the compartment providing physical and visual protection to the contents of the compartment and a pusher is provided to facilitate removal of the items.

A clip suitable for holding money, credit cards and document is described. The clip includes features that enable use of decorative leather, cloth, rubber, polyester or polyurethane covers that can be interchanged and conceal the inner, typical metal, workings of the clip.
