Problems solved by technology

[0002] Card reader (Card Reader) is a card reading device, according to the different types of cards, it can be divided into IC card readers, including contact IC cards, non-contact IC cards; currently non-contact card readers It is widely used in the fields related to identity verification, such as the cooperation of contactless card reader and fingerprint card to complete user identity verification. The verification process between the card reader and the fingerprint card is completed based on the non-contact field strength. When the time interval for the field strength sent by the non-contact card reader is long or the field strength sent by the card reader is weak, it cannot meet the requirements. The need for a fingerprint card, making it impossible to perform security verification

Embodiment 1

[0029] Embodiment 1 of the present invention provides a working method of a card reader auxiliary device, the card reader auxiliary device is attached to the card reader, and is used to provide a non-contact field for the fingerprint card during the interaction process between the fingerprint card and the card reader, It can make the fingerprint card obtain enough power for fingerprint comparison.

[0030] Such as figure 1 As shown, the method includes:

[0031] Step 101, the card reader auxiliary device detects whether there is a card based on the non-contact field of the card reader, and starts a timer when the presence of the card is detected, and opens its own non-contact field;

[0032] Step 102, the card reader auxiliary device obtains the current time of the timer, and judges whether the current time is greater than the first preset time, if yes, execute step 103, otherwise return to execute step 102;

[0033] Step 103, the card reader auxiliary device turns off its o...

Embodiment 2

[0056] Embodiment 2 of the present invention provides a working method of a card reader auxiliary device, such as figure 2 Shown is a structural block diagram of the card reader auxiliary device, the card reader auxiliary device includes a main control module, a sending module, a receiving module and a power management module; the card reader auxiliary device is used for the interaction process between the fingerprint card and the card reader, through The contactless field provided by the card reader auxiliary equipment can enable the fingerprint card to obtain enough power for fingerprint comparison.

[0057] Such as image 3 As shown, a working method of a card reader auxiliary device includes:

[0058] Step 201, the auxiliary device of the card reader is powered on, and the system is initialized;

[0059] The power-on of the card reader auxiliary equipment is as follows: powered by the built-in power supply in the card reader card holder, such as battery power or capacit...

Embodiment 3

[0121] Embodiment 3 of the present invention provides a working method of a card reader auxiliary device, the card reader auxiliary device includes a first coil, a second coil, a main control module, a sending module and a receiving module; Figure 4 The schematic diagram of the auxiliary device of the card reader is shown. The auxiliary device of the card reader is used for the interaction process between the fingerprint card and the card reader. Through the non-contact field provided by the auxiliary device of the card reader, the fingerprint card can obtain enough power for fingerprinting. Comparison.

[0122] Such as Figure 5 As shown, a working method of a card reader auxiliary device includes:

[0123] Step 301, the auxiliary device of the card reader is powered on, and the system is initialized;

[0124] Specifically, in this embodiment, the auxiliary device of the card reader is powered on as follows: powered by the built-in battery in the card reader sleeve;

[01...

Abstract

The invention discloses a card reader auxiliary device and its working method, and belongs to the field of card readers; the invention uses the card reader auxiliary device to detect whether there is a card based on the non-contact field of the card reader, and reads the card when the card is detected. The card reader auxiliary device opens its own non-contact field to provide sufficient field strength for the fingerprint card, so that the fingerprint card can complete the fingerprint comparison. The card reader auxiliary device obtains the current time of the timer and judges whether the current time is greater than the first preset time. If it is, close its non-contact field. By adopting the present invention, the fingerprint comparison of the card can be realized without upgrading the card reader, so that the card and the card reader can successfully complete the communication.

Description

technical field [0001] The invention relates to the field of card readers, in particular to a card reader auxiliary device and a working method thereof. Background technique [0002] Card reader (Card Reader) is a card reading device, according to the different types of cards, it can be divided into IC card readers, including contact IC cards, non-contact IC cards; currently non-contact card readers It is widely used in the fields related to identity verification, such as the cooperation of contactless card reader and fingerprint card to complete user identity verification. The verification process between the card reader and the fingerprint card is completed based on the non-contact field strength. When the time interval for the field strength sent by the non-contact card reader is long or the field strength sent by the card reader is weak, it cannot meet the requirements. Fingerprint card requirements, so security verification cannot be performed. Contents of the invent...
