MIDDLEWARE DEVICE, DRIVING METHOD OF READER AND METHOD FOR DETERMINING MISRECOGNITION OF TAG
First Claim
1. A method for determining tag misrecognition by a middleware device that is operated in relation to a reader, the method comprising:
- pre-storing receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader;
acquiring the receiving sensitivity of tag information of the tag recognized at a preset time interval while the object is passing within a range of the reader; and
determining misrecognition of the tag by comparing the acquired receiving sensitivity with the pre-stored receiving sensitivity of tag information.

Abstract
A middleware device, a driving method of a reader and a tag misrecognition determining method are provided. The middleware device operated in relation to a reader includes a storage configured to pre-store receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader as a reference value, a communication interface configured to, in response to the object approaching to the reader, acquire the receiving sensitivity of tag information of the tag recognized at a preset time interval, and a tag misrecognition processor configured to compare the acquired receiving sensitivity with the pre-stored reference value to determine misrecognition of the tag.

9. A method for driving a reader that is operated in relation to a middleware device, the method comprising:
-
measuring, by a reader, receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader; transmitting the measured receiving sensitivity to the middleware device; measuring, by a reader, the receiving sensitivity of the tag information of the tag recognized at a preset time interval while the object is passing within a range of the reader; and transmitting the receiving sensitivity measured according to the preset time interval to the middleware device for comparison with measured receiving sensitivity according to the different distances in order to determine misrecognition of the tag. - View Dependent Claims (10, 11, 12)
