An adhesive-backed electrical discharge patch that can be applied to clothing, bags, or directly to skin, delivering a 55,000-volt shock to anyone who touches the protected surface. The TS-3 is a thin, flexible circuit printed on a polymer substrate with a pressure-sensitive trigger — any contact pressure above 500 grams activates the discharge. The user's own skin is insulated by the adhesive backing, while the outer surface is the active electrode.

Axiom Systems markets the TS-3 as passive defense — protection that works even when the user cannot actively respond. Patches are commonly applied to purse straps, jacket shoulders, backpack handles, and anywhere a pickpocket or grab-attacker is likely to make contact. The patches are disposable, with each containing a single-discharge capacitor that depletes on first activation. They are sold in packs of five for Φ60.

The TS-3 has found unexpected popularity among delivery workers and couriers who are frequently targeted for their cargo. Applied to the handles of delivery containers, the patches deter grab-and-run theft with painful consistency. The primary limitation is single-use — once triggered, the patch is spent and must be replaced. Axiom is developing a rechargeable variant, but the current disposable model dominates the market.
