The trick of lightening different specified Tag (HL5303) is easily using by HL5308 reader. When Tag was appeared in the antenna field, HL5308 will first detect the Tag-ID then shine the HL5303 when it was close to antenna. As this characteristics, we could quick turn off the antenna power when got the wrong Tag-ID. It seems magic to lighten the specified Tag.
