Definitions
- SUBSTANCE invention relates to smart cards made in the form of rings and operating on Near Field Communication (NFC) wireless data transmission technology. These smart cards can be used to make contactless payments, as tickets when using public transport or when attending a mass event, authentication, information exchange, and more.
- NFC Near Field Communication
- Contactless smart cards allow the bank account holder to make transactions by exchanging information between a contactless payment device and a reader over an RF channel.
- the resonant circuit of smart cards includes, as a rule, a connected antenna, a capacitor and a microchip.
- a contactless smart card in the form of a ring is known from the prior art (CN 203930905 U, 05.11.2014), containing a printed circuit board in the form of an arc, on which a loop antenna and an NFC microchip connected to it are placed, and a multi-component housing consisting of the following parts: a body with a recess for accommodating a printed circuit board on a surface oriented to the opposite side from the user's finger, a shielding layer covering the recess, and an outer protective layer.
- the disadvantages of this solution are complex and unreliable design.
- Several elements of the case make it massive and unstable to loads, since the outer side is most often subject to mechanical stress, including shock, which can lead to detachment of parts of the case, damage to the printed circuit board and failure of the payment device.
- a contactless smart card in the form of a ring (WO 2018020055 A1, 02/01/2018) was chosen, containing a one-piece body and connected loop antenna, a capacitor for finer tuning of operation and a microchip on a conductive pad that supports NFC technology.
- the one-piece case has a frusto-conical recess on the inner side designed to fit the finger to accommodate the antenna, capacitor, and microchip.
- the cone of the notch is directed inside the body and has a base height of 8 mm, while the height of the entire ring is 9 mm, so on the inner side of the ring there is 0.5 mm left on the protrusions of the body on each side until the notch, which is subsequently sealed along the entire height.
- This smart card provides more security components of the contour, however, the thin edges of the housing protrusions on the inside before the notch make it not strong enough.
- the disadvantages of the ring are also its massiveness, since the case is made quite wide due to the recess, and the complexity of production, since the conical shape of the recess requires a special approach in manufacturing, plus the installation of a capacitor is required, which, according to the authors, is necessary for more precise tuning of the smart -cards.
- the objective of the invention is to create a contactless smart card in the form of a ring containing a recess on the inner side facing the user's finger and having the smallest number of constituent elements, less massiveness, simplified design, increased operational and production reliability while maintaining the advantages achieved by the prototype.
- the technical result consists in reducing the weight and size characteristics of a ring with a solid body and a recess on the inner side while maintaining the health of the resonant circuit of the smart card and protecting its components from external mechanical influences.
- a contactless smart card in the form of a ring containing a connected loop antenna with a microchip on a conductive pad that supports NFC technology and a one-piece body, in which a recess is made on the side intended to fit to the finger, accommodating an antenna with a microchip and sealed in its height, the microchip is made with an electric capacitance that ensures the operability of the smart card, and the recess is made rectangular with a height of not more than 5.0 mm and a depth of not more than 1.5 mm, while the thickness of the protrusions of the housing above the recess is from 1.0 to 1.5 mm.
- the microchip is made with an electric capacitance of at least 78 pF.
- the mass and dimensions of the ring are reduced while maintaining and even increasing the protection of the components of the resonant circuit (microchip with a loop antenna) from external mechanical influences.
- Security is not only affected by the thicker housing protrusions above the notch, but also by reducing the number of parts that can fail by eliminating the capacitor and using a microchip with an electrical capacitance that ensures the operation of the smart card.
- the implementation of a rectangular recess also provides a simplification of the design - such a recess is made faster, with less likely to be defective and easier to seal than a cone, in addition, it is easier to ensure the correct positioning of the microchip with the antenna.
- Figure 1 schematically shows the connected microchip and loop antenna.
- Figure 2 shows a housing with a notch.
- a contactless smart card in the form of a ring can be used for contactless payments, when using public transport or when attending a mass event, authentication, information exchange or other.
- the device contains a connected semiconductor microchip 1 on a conductive pad 2 and a loop antenna 3, the contacts of which are connected to the contacts of the microchip 1, as well as a solid body 4.
- the microchip 1 supports the NFC technology and is made with an electrical capacitance sufficient to ensure the operability of a smart card and, as a rule, not less than 78 pF.
- the specified required capacitance value was obtained as a result of testing microchips with different capacities.
- the performance of a smart card means, in fact, the performance of its resonant circuit, namely, the provision of the possibility of stable interaction with the reader.
- the housing 4 is provided on the inner side, designed to fit to the finger, with a rectangular recess 5 containing a microchip 1 with a loop antenna 3, which has a length L from 310 to 490 mm and fits into such a number of turns that provides a stable resonant frequency of the oscillatory circuit.
- the recess 5 is a groove or recess made along the entire circumference of the inner side of the ring (figure 1, 3), and has a height H of not more than 5.0 mm and, as a rule, not less than 2.0 mm, and a depth D, typically 1.2 to 1.5 mm.
- the recess 5 is sealed along its height flush with the protrusions of the body so that the inner side of the ring is smooth.
- a sealant a coating of ceramic, plastic, two-component epoxy pigmented compounds (epoxy resins) or composites based on a ceramic matrix is used.
- the body 4 is made with a height W from 4.0 to 8.0 mm, a total thickness T from 2.0 mm to 2.8 mm, a thickness of the protrusions 6 above the recess from 1.0 to 1.5 mm and a ring size S in range from 15 to 25 (Fig.3).
- the housing 4 may be made of ceramic, plastic, epoxy resin or composite material.
- the specified parameters of the product make it possible to reduce the mass and dimensions of the ring while maintaining the health of the resonant circuit of the smart card and the protection of its components from external mechanical influences.
- a hole can be made on the case to install an LED 7 to indicate that a smart card has entered the coverage area of a reader, which can be a smartphone that supports NFC technology, a payment terminal, a turnstile or a lock with contactless activation, and other devices.
- a reader which can be a smartphone that supports NFC technology, a payment terminal, a turnstile or a lock with contactless activation, and other devices.
- a contactless smart card in the form of a ring works as follows.
- a body 4 of the ring is made with a size S in the range from 15 to 25 with a rectangular recess 5 with a height H from 2.0 to 5.0 mm and a depth D from 1.2 to 1.5 mm for the selected microchip 1 NFC on a conductive pad 2 with a capacitance, for example, 78 pF, as well as a thickness of the housing protrusions above the recess from 1.0 to 1.5 mm.
- An antenna 3 with a length L from 310 to 490 mm is selected, which is placed in a certain number of turns to ensure a stable frequency of the resonant circuit and connected to the contacts of the microchip 1.
- the connected components are placed in a rectangular recess 5 (figure 2-3), which is sealed flush with the surface of the inner side of the housing 4.
- the personal payment data of the user and the payment application of the issuing bank are recorded on the microchip 1, which interacts through the payment system with the acquiring bank of the seller during the payment transaction.
- the data is stored encrypted with crypto keys and protected from overwriting or modification.
- the finished ring with encoded data is put on the finger by the user so that the inner smooth side of the ring, consisting of projections 6 and recess sealant 5, is adjacent to it.
- the resonant circuit formed by the loop antenna 3 together with the microchip 1 with capacitive characteristics ensures the transmission of encoded information over a radio frequency channel over a distance of at least 2 cm.
- the circuit components With active movement and receiving mechanical impacts in the form of possible impacts on the body 4 and its ends, including recesses 6, the circuit components are not damaged and remain in working condition due to a smaller number of parts and thicker walls of the body with a general reduction in product dimensions.
- the use of a special capsule to seal the inside of the ring can make it possible to achieve water resistance of the product, which will make possible water procedures without losing the performance of the smart card.
