[0002] In the current contactless card reader, the antenna parameters or positions are fixed after the design is completed, and it can only adapt to certain types or types of contactless cards, but cannot adapt to more types of cards.
And the center of the general PCB antenna, close to the position of the antenna plane, is prone to card reading blind spots, resulting in card reading failure; The antenna package of the card deviates from the center, causing the position of the card antenna to deviate from the antenna area of the card reader, and the card reading effect of the card reader will be poor; if the resonance point of the contactless card antenna is too high or too low, it will also cause the card reading effect poor

Embodiment 1
[0074] Embodiment 1 of the present invention provides a method for improving the adaptability of a contactless card reader, such as figure 1 As shown, the method of this embodiment includes:
[0075] Step 101: the card reader activates the card detection device;
[0076] Specifically, in this embodiment, the card detection device includes: an infrared position recognition device, an image position recognition device, an antenna signal feedback recognition device, etc.;
[0077] Step 102: The card reader detects whether there is a card entering the card inspection area through the card detection device, if yes, execute step 103, otherwise return to step 102;
[0078] Step 103: The card reader performs card inquiry operation according to the preset first method;
[0079] Step 104: The card reader judges whether the card inquiry operation is successful, if yes, the card reader and the card start to communicate, otherwise, execute step 105;
[0080] Step 105: The card reader ch...
Embodiment 2
[0435] Embodiment 2 of the present invention provides a device for improving the adaptability of a contactless card reader, such as Figure 34 shown, including:
[0436] Starting module 21, used to start the card detection device;
[0437] The first judging module 22 is used to detect whether a card enters the card inspection area through the card detection device;
[0438] The card inquiry module 23 is used to perform the card inquiry operation according to the preset first mode and the modified first mode when the first judging module 22 judges that a card enters the card inspection area;
[0439] The second judgment module 24 is used to judge whether the card inquiry operation of the card inquiry module 23 is successful, if so, the card reader and the card start to communicate;
[0440] The modifying module 25 is configured to modify the first mode when the second judging module 24 judges that the card inquiry operation is unsuccessful.
[0441] In this embodiment, the car...

Abstract
The invention discloses a method and device for improving the adaptability of a contactless card reader. The method includes the following steps that 1, the card reader starts a card detection device; 2, the card reader detects whether or not a card enters a card detection region through the card detection device, if yes, the step 3 is executed, and otherwise, the step 2 is repeated; 3, the card reader conducts card inquiring operation according to a first preset mode; 4, the card reader judges whether the card inquiring operation is successful or not, if yeas, the card reader starts to be in communication with the card, and if not, the step 5 is executed; 5, the first mode is changed by the card reader, the card inquiring operation continues to be conducted according to the changed first mode, and then the step 4 is repeated. According to the method and the device, on the premise that a user does not replace hardware, the card reader can adapt to more types of the cards or the cards different in size, the card reading effect of the card reader is better, and the adaptability of the contactless card reader is improved.
