Embodiment 1

[0028] figure 1 The composition structure of the NFC antenna module provided by the first embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0029] Such as figure 1 As shown, the NFC antenna module 1 includes at least two NFC antenna coils 11 .

[0030] Preferably, the NFC antenna module 1 includes at least two NFC antenna coils 11 with different area sizes;

[0031] Preferably, among the at least two NFC antenna coils with different sizes, the smaller NFC antenna coil is embedded in the larger NFC antenna coil, and the at least two NFC antenna coils with different sizes are on the same plane. figure 2 An example is given, the NFC antenna module includes two NFC antenna coils with different sizes, wherein the NFC antenna coil with a small area is built into the NFC antenna coil with a large area, and the two NFC antenna coils with different sizes The NFC antenn...

Embodiment 2

[0044] Figure 4 The composition structure of the card reader or the smart card provided by the second embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0045] Such as Figure 4 As shown, the card reader or smart card 4 includes a multi-channel controller 41, and an NFC antenna module 42 as described in Embodiment 1 connected to the multi-channel controller 41;

[0046] The multi-channel controller 41 is used for reading data from at least two NFC antenna coils 421 in the NFC antenna module 42 in a polling manner. That is, when the multi-channel controller 41 has no response to a certain NFC antenna coil 421 reading data, read the data of another NFC antenna coil 421 until the highest degree of overlap is obtained, that is, the easiest NFC antenna coil to read data 421.

[0047] Specific application scenarios using the foregoing embodiments are given below.

Abstract

The invention belongs to the technical field of data communication, and provides an NFC antenna module, a card reader and an intelligent card. The NFC antenna module comprises at least two NFC antenna coils. With the adoption of the NFC antenna module, the card reader and the intelligent card, the problems that the NFC antenna on a conventional card reader has poor sensitivity and high probability of signal unsteadiness during card reading, and even has a signal blind zone at times can be solved.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to an NFC antenna module, a card reader and a smart card. Background technique [0002] Near Field Communication (NFC) is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission and exchange of data between electronic devices. [0003] The NFC antenna is an important part of the card reader. In the prior art, the NFC antenna is installed on the circuit board of the card reader or the NFC antenna is integrated with the circuit board of the card reader, which can only be applied to standard smart cards. When some special-shaped smart cards (non-standard smart cards) and smart cards with relatively small areas use the card reader, due to the low sensitivity of the NFC antenna on the card reader, the signal is unstable when swiping or reading the card, or even Sometimes there is a problem with signal...
