BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to technology filed of card readers, and more particularly to a card reader device for facilitating normal users and visually impaired users be able to input their card password with safety.
2. Description of the Prior Art
Nowadays, high-technology electronic devices make consumers change their habit of paying. For example, consumers finish their payment transactions by the use of a specific financial transaction tool except for cash. The specific financial transaction tool can be credit card, debit card, chip card, prepaid card, or electronic wallet.
Although the various financial transaction tools have been widely applied in payment transaction, consumers still worry about the security of payment and owner identification during the payment transaction. Therefore, before the payment transaction is made to be effective, a consumer is demanded to input a specific password for confirming consumer's identity through a specific electronic device like card reader. FIG. 1 shows a stereo view of a conventional point of sale (POS) system. As shown in FIG. 1, the conventional POS system 1′ mainly comprises: a card reader 11′ and a touchscreen 12′, wherein a financial card 2′ such as credit card can be accessed by the card reader 11′ for carrying out a payment transaction after being inserted in to a card receiving groove of the card reader 11′. Before the payment transaction is made to be effective, the touchscreen 12′ would show a virtual keyboard 13′ comprising a plurality of virtual buttons 131′ randomly arranged for a user to input a password thereon. After the password is inputted successfully, the POS system 1′ transmits user data comprising card No. and user identity to a database of a bank for identity authentication. As a result, the user pays his bill payment by the use of the financial card, without using cash.
However, the POS system 1′ is just designed for normal users. It is extrapolated that, it is difficult or even impossible for any blind users to recognize each of the virtual buttons 131′, so as to finish their password input. Besides, when the blind user input the password, the password is easily peeked by other people with normal sight.
Through above descriptions, it is known that the conventional POS system integrated with card reader still show drawbacks and shortcomings. In view of that, inventors of the present application have made great efforts to make inventive research thereon and eventually provided a card reader device.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a card reader device, comprising: a card reader unit, a human machine unit, a physical keyboard, and a virtual keyboard-to-physical keyboard conversion unit. The human machine unit is configured to show a first virtual keyboard comprising a plurality of first virtual buttons randomly arranged for a normal user to input a password thereon. More particularly, the physical keyboard comprises a plurality of physical buttons, and each of the physical buttons is provided with an embossed braille thereon. According to particular design of the present invention, a plurality of the second virtual buttons are showed on the human machine unit, such that the plurality of physical buttons correspond to the plurality of second virtual buttons, respectively. Consequently, a blind user or a visually impaired user is facilitated so as to be capable of completing a password input of the card reader unit through the physical keyboard. Therefore, this novel card reader device makes both visually impaired user and normal user be able to finish a safety password input of the card reader unit.
For achieving the primary objective of the present invention, the inventor of the present invention provides an embodiment for the card reader device, comprising: a card reader unit;
- a human machine unit, being electrically connected to the card reader unit; wherein the human-machine unit is configured to show a first virtual keyboard comprising a plurality of first virtual buttons randomly arranged for a normal user to input a password thereon;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
To more clearly describe a card reader device, embodiments of the present invention will be described in detail with reference to the attached drawings hereinafter.
With reference to FIG. 2, there is provided a first stereo diagram of a card reader device according to the present invention. Moreover, FIG. 3 shows a second stereo diagram of the card reader device. The card reader device 1 of the present invention comprises: a card reader unit 101, a human machine unit 101, a physical keyboard PK, and a virtual keyboard-to-physical keyboard conversion unit, wherein the human machine 111 is electrically connected to the card reader unit 101. As explained in more detail below, the human machine unit 111 is configured to show a first virtual keyboard VK1 comprising a plurality of first virtual buttons randomly arranged for a normal user to input a password thereon.
Continuously referring to FIG. 2 and FIG. 3, in which the physical keyboard PK is integrated on the human machine unit 111, and comprises a plurality of physical buttons formed with a braille embossed thereon. Particularly, a virtual keyboard-to-physical keyboard conversion unit is provided in the human machine unit 111 for identifying a plurality of first virtual positions of the plurality of first virtual buttons, so as to correspondingly convert the first virtual positions to a plurality of second virtual positions. By such arrangements, the virtual keyboard-to-physical keyboard conversion unit shows a second virtual keyboard VK2 comprising a plurality of second virtual buttons through the human machine unit 111, and then makes each of the plurality of second buttons be identified to has one second virtual position. Therefore, the plurality of second virtual buttons are able to correspond to the plurality of physical buttons, respectively. Consequently, a blind user or a visually impaired user is facilitated so as to be capable of completing a safety password input of the card reader unit 101 through the physical keyboard PK. It needs to further explain that, the card reader device 1 further comprises a plurality of anchor points. More particularly, the plurality of anchor points are disposed on the lower surface of physical keyboard PK, such that the human-machine 111 make the plurality of second virtual buttons individually correspond to the plurality of physical buttons based on the plurality of contact position of anchor points.
Inheriting to above descriptions, the card reader device 101 accesses a card from a normal user or a visually impaired user based on radio frequency identification technology (RFID) or near field communication technology (NFC). Besides, the card reader device 101 also accesses a card from the normal user or the visually impaired user based on bar code scanning technology, magnetic strip card decoding technology or smart card identify technology. It is worth explaining that, the human machine unit 101 is selected from group consisting of tablet PC, laptop computer having touchscreen, all-in-one touch computer, smailphone, portable point of sale (POS) device having touchscreen, and POS device having touchscreen.
