Protective badge holder for your contactless cards. The holder prevents data theft or abuse. The RFID cards can be abused in several different ways, from hidden smart labels under the table, to terminals hidden in people's pockets in a crowded area. This data theft cannot be detected until we receive the bill by the end of the month or until our systems have been accessed without our consent. For this purpose we have prepared protective badge holders to prevent your card frequencies from being hijacked. Apart from security, these holders are an excellent way to promote yourself since they can be imprinted with the logotype of your choosing.
