Product Detailed
reading range:2-5m communication port:RS232/485, wiegand 26/32bits frequency:865-928MHz

On the current market, all the active tag readers with direction have a common, that is, on the back of the antenna can also read the signal the label launches, the reading region when it works is as below figure:

ACM-818Z is a patent product developed by Goldbridge Co. The reading region when it works is as below:
