## Abstract

The present disclosure provides a RFID terminal and a method of using the same. The RFID terminal includes: a directional antenna module configured to directionally receive a signal transmitted by an electronic tag on an item in a region to be read; a camera configured to collect an image of the region to be read; and a control unit configured to screen information of a target item according to the image of the region to be read captured by the camera.

## Claims

### Claim 1

A method of using a RFID terminal, the RFID terminal comprising:
a directional antenna comprising a reception range, and configured to directionally receive signals transmitted by electronic tags on items in a region to be read;
a camera configured to collect an image of the region to be read, wherein the reception range of the directional antenna is located within a field of view of the camera;
a display screen configured for a user's operation to select an item within a region; and
a controller configured to adjust the reception range of the directional antenna according to a range of the item selected by the user on the display screen, and screen information of a target item according to the image of the region to be read captured by the camera;
the method of using the RFID terminal comprising:
capturing, by the camera, an image of the region to be read,
displaying, by the display screen, the image of the region to be read in the display region;
receiving, by the directional antenna, the signals transmitted by the electronic tags in the region to be read;
manually selecting an item in the image on the display screen; and
screening information of the selected item;
wherein the manually selecting the item in the image on the display screen comprises:
selecting a first region and a second region in the image, respectively; and
reading information of the item in an intersection set region, an union set region, or a complementary set region between the first region and the second region according to a preset manner.

### Claim 2 (depends on 1)

The method according to claim 1, wherein a display range of the display region substantially coincides with the reception range of the directional antenna, and the display region varies with a variation of the reception range of the directional antenna.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the screening information of the selected item comprises:
comparing, by the controller, an image of the item selected by a user with an image in an image library stored in a memory via a deep learning neural network to identify the item selected by the user.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the controller selects information of all items, which has a same kind as the item selected by the user, from information of all electronic tags received by the directional antenna according features of the information of the electronic tags on different items.

### Claim 5 (depends on 1)

The method according to claim 1, the screening information of the selected item further comprising: adjusting the reception range of the directional antenna to a range at which the selected item is located, and receiving the signal transmitted by the electronic tag on the selected item.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising:
displaying, by the controller, the items in the region to be read on the display screen in categories for the user to select the target item.

### Claim 7 (depends on 6)

The method according to claim 6, further comprising:
displaying, by the display screen, only the information of the item selected by the user; or
displaying, by the display screen, only the information of other items other than the item selected by the user.
