These tiny, inexpensive devices will send your message to anyone with an Android phone that has Bluetooth and location turned on within 100 meters. That is more than a football field.
Just for being nearby, these messages appear in the same place that you see your email or Facebook notification. No app download needed. Simply pull down the notification from the top of your Android phone.
This is where your customized 40-characters notification appears. When the user touch the message, they will be sent to your website, landing page, coupon, or video. This message will broadcast 24/7. The battery lasts up to 2 years.
