Description

[0001] The invention relates to an electronic component for contactless digital interaction, in particular for providing machine-readable information by means of near-field communication and optical detection. In particular, the component is portable.

[0002] Electronic components with integrated NFC chips or printed QR codes are known from the prior art. They are implemented, for example, as cards, badges, or signs that are either permanently mounted or worn loosely.

[0003] US 7523870 discloses a portable electronic component protected by a sleeve. The invention aims to protect the privacy and security of information on RFID cards by preventing these cards from being read by unauthorized readers when not in use. The special shielded holder is a sleeve or case made of materials that block radio waves. When the RFID card is in this holder, it cannot communicate with readers, thus keeping your information private and secure.

[0004] WO 2025 / 085496 discloses a wearable electronic component integrated into a lanyard. A tag without any electronic component hangs from the lanyard. The patent thus describes a lanyard that integrates electronic components directly into the strap itself. This means that small electronic components such as microphones, speakers, control buttons, or wires are embedded in the fabric or material of the lanyard. These components allow the user to communicate with other devices, make or receive calls, adjust the volume, or connect headphones while wearing the lanyard around the neck as usual.

[0005] Furthermore, holding devices and extension mechanisms are known with which objects such as keys or identification cards can be attached to a user's body and temporarily moved away from him.

[0006] However, these known solutions are generally designed for use by the wearer themselves or for interaction with permanently installed counterparts, such as locks or stationary readers.

[0007] With known electronic components for digital interaction, the problem is in particular that: - contactless interaction with third-party mobile devices often requires the component to be handed over or detached from the carrier, - the required distance or line of sight for NFC or QR-based interactions in a conversational or movement context is difficult to reliably establish, - loose or removable components can easily be lost or damaged.

[0008] The invention is therefore based on the objective of providing an electronic component that enables contactless digital interaction with mobile devices of interaction partners, without the electronic component having to be detached from the carrier or handed over to the interaction partner.

[0009] This problem is solved by an electronic component with the features of the main claim. Advantageous embodiments are described in the dependent claims.

[0010] The basic idea of ​​the invention is to provide an electronic component in which an interaction carrier with digital functionality is connected to a holding housing via an extension mechanism, so that the carrier can be moved in a targeted and temporary manner towards a mobile device of a third party in order to enable contactless reading.

[0011] The electronic component is specifically designed to perform contactless digital interaction with mobile devices of interaction partners who are not carriers of the electronic component.

[0012] For this purpose, the plate in which the NFC chip is integrated and on which the QR code is printed is connected to the housing via the extension mechanism, the extension mechanism being designed in such a way that the plate can be moved from a holding position towards a mobile device of an interaction partner in order to carry out the contactless digital interaction.

[0013] The extension mechanism not only serves to secure the plate against loss, but also represents a functional means for carrying out digital interaction by enabling the wearer to precisely adjust the distance required for NFC-based communication and / or optical scanning of the QR code, while the housing of the electronic component remains on the wearer's body.

[0014] After the interaction is complete, the plate is automatically returned to the housing by the extension mechanism, ensuring that the electronic component remains attached to the carrier and is not transferred to the interaction partner throughout the entire interaction. The digital interaction thus takes place as intended between the interaction partner's mobile device and the electronic component of the carrier.

[0015] The electronic component has a plate with an integrated NFC chip. At least one QR code is printed on the plate, suitable for optical scanning by a mobile device.

[0016] The plate is connected to a housing via an extension mechanism, which can be attached, for example, to a belt, a bag or a piece of clothing worn by the wearer.

[0017] The NFC chip and the QR code each provide information that enables digital interaction. This information, such as a link or email address, can be identical, corresponding, or complementary. However, it is preferable for them to be identical so that as many types of mobile devices as possible can be used by the interaction partners.

[0018] The combination of NFC and QR code enables multimodal interaction that can be carried out regardless of the technical characteristics or settings of the mobile device of the interaction partner.

[0019] The extension mechanism allows the user to move the plate from a holding position towards a mobile device of an interaction partner in order to establish a suitable distance or line of sight for contactless reading.

[0020] After the interaction is complete, the extension mechanism automatically returns the plate to the housing, so that the electronic component remains attached to the carrier.

[0021] The design according to the invention enables a digital interaction which: - without handing over the electronic component, - without detaching the component from the carrier, - can be reliably carried out even in dynamic conversation or movement situations, - offers increased protection against loss.

[0022] In a preferred embodiment, the plate is designed as a flat disc. This ensures good visibility and ease of handling during the optical scanning of the QR code.

[0023] If the electronic component for contactless digital interaction is designed to be portable, interaction with mobile devices of interaction partners can be carried out without having to put down or hand over the electronic component.

[0024] If the housing has fastening means, such as a buckle or carabiner, for attaching the housing to, for example, a garment or a belt, the housing is held in an essentially stationary position during the interaction and the movement generated by the extension mechanism is specifically limited to the plate.

[0025] The QR code can be placed on one or both main surfaces of the disc.

[0026] The plate is preferably made of a UV and abrasion-resistant material to ensure permanent readability of the QR code and long-term functionality of the electronic component.

[0027] In one embodiment, the NFC chip integrated into the plate and / or the printed QR code is configured to point to a digital target address managed outside the electronic component. The mapping between the electronic component and the digital target address can be changed without requiring any physical modification of the electronic component. This allows the digital information provided by the NFC chip and / or the QR code to be adapted while the electronic component remains unchanged.

[0028] One embodiment is shown in the drawing and is described in more detail below. It shows the Fig. 1 the entire electronic component and Fig. 2. An exploded view of the plate.

[0029] The electronic component 1 essentially consists of a plate 2 and an extension mechanism 3. The plate 2 has, as shown in the Fig. Figure 2 shows an integrated, invisible NFC chip (4). A QR code (5) is printed on the plate. This plate (2) looks essentially the same on both sides, as the QR code (5) is printed on both sides. Additional information, logos, and codes may also be printed on the plate, which are not shown here.

[0030] The NFC chip 4 can contain information matching or corresponding to the code, or additional information.

[0031] In the exemplary embodiment, the plate 2 is designed as a round disk 6 with a diameter of approximately 6 cm. Regardless of the diameter, the plate can be only a few millimeters thick, such as about 2 mm.

[0032] The disk 6 has a bore 7 in which a ring 8 is arranged. This ring 8 runs through a bore 9 in a plate-side end piece 10 of an intermediate piece 11. The intermediate piece 11 has the plate-side end piece 10 and an opposing end piece 12, which are connected to each other by a flexible spacer 13.

[0033] A cord 14 is attached to the opposite end piece 12, leading into a housing 15. Inside the housing 15 is a spring 16 (shown only schematically) which pulls the cord 14 into the housing 15.

[0034] When using the spacer 13, the spring 16 pulls the cord 14 into the housing 15 until the opposite end piece 12 hits the housing 15.

[0035] If no spacer is used, the spring 16 pulls the cord 14 into the housing 15 until the disc or a plate-side end piece 10 abuts the housing 15.

[0036] The durability of plate 2 is increased by the fact that it is made from a UV-resistant material. QUOTES INCLUDED IN THE DESCRIPTION
