Description

Tablet computer with near-field communication card simulation function

Technical Field

The utility model relates to the technical field of terminal near field communication, in particular to a tablet personal computer with a near field communication card simulation function.

Background

Near field communication (near field communication), devices using NFC technology (such as mobile phones) can exchange data in close proximity to each other, and is evolved from the integration of contactless Radio Frequency Identification (RFID) and interconnection technology. The induction card reader and the induction card are integrated on a single chip to realize the function of point-to-point communication, and the mobile terminal is utilized to realize the applications of mobile payment, electronic ticketing, entrance guard, mobile identity recognition, anti-counterfeiting and the like. Through the NFC function, wireless connection and data sharing can be conveniently achieved among various electronic devices such as mobile phones, PDAs (tablet personal computers) and computers.

For the PAD or the computer, when the NFC card has the NFC card simulation function, the NFC card can be read by external NFC equipment in an induction mode, and then the near field communication function is completed. In order to have the NFC card simulation function, many computer products directly attach a passive NFC tag to the lower right corner of a keyboard key, as shown in fig. 1. It is clear that this solution is not applicable to PAD, whether from a structural or appearance point of view. In addition, to PAD, often there is very big screen, and the screen has the protection of metal protection cover moreover, and the shell is generally also the metal material, and the metal can shield NFC antenna performance.

Therefore, it is difficult to design an NFC antenna for a PAD to have an NFC card simulation function, and a solution is needed.
