The batwings are larger than postage stamp, but means it can operate to a few tens of feet.The technology feels like magic the first time you see it. Some major clothing retailer uses such technology.</p><img src="https://community.element14.com/aggbug?PostID=6348&AppID=96&AppType=Weblog&ContentType=0" width="1" height="1">
