In a modern digital world, where everything is tracked, monitored, and logged, a return to the old ways might make all the difference for your operational and personal security one day.

These covert signaling reference decals are used to reinforce the recollection of common codes used for covert and rescue communications. Tap code was a common form of passing information audibly by detainees and prisoners of war who had no other means of communicating. While it is most often associated with tapping or knocking on a wall, it can also be delivered via flashlight signaling or other means and methods.

The same is true for Morse code. These decals can be adhered to the back of a credit card, under the sole of your shoe, or the back of your phone, so they're always with you when you need them. Although it might be best to devote time to memorizing these tables, it can be a literal lifesaver one day to have these reference guides available when you need them most. 

Combine this decal purchase with the Hobo Signs and Emergency Symbols Decal 2-Pack and the Emergency Communications Decal 2-Pack to maximize your knowledge base and options when the chips are down. Learn, train, or refer to them in a worst-case scenario.

This product is sold as a pack of two decals, because two is one and one is none. Each sticker is 3.5 inches wide and two inches tall, in a semi-gloss finish. They are peel and stick, allowing you to adhere them to a wide variety of surfaces. Due to their water-resistant coating, you can place them both outdoors or indoors.
