Tum jese dehati ganvar ki soch hai kapade me jadu thode na hai ki bina kisi tag k bajne lagega or ye alarm sirf plastic ke tag se bajta hai ye sticker nahi bhi nikalata to bhi nahi bajata
Mall pe Plastic tag bhi laga rehta hai jo ese nahi hat ta sirf payment vaali jagah pe hi hat ta hai , aur agr voh laga reh gya aur chahe pehnke ya kese bhi baahr nikle to us tag me magnetic lagi rehti hai aur gate pe sensor laga hota hai , magnetic waves catch krne ka to kese nikloge vaha se?
