I need about a coverage area of 7 meter by 2 meter range, the MCU devices Ive found online seem more geared toward close contact (in centimeter ranges) like ID cards / key fobs / badges etc. Also I need to scan hundreds of tags within seconds. But I'm no expert, I'm learning. I haven't been lucky in finding open source software for the task. -- Waitman Gobble Los Altos California USA 510-830-7975
