SD Port Blockers can be inserted into SD card ports on memory readers, in cameras, and other devices. These devices provide a visual deterrent to anyone looking to copy data or viruses from, or to, an SD card.
The SD Port Blocker is made up of a combined "key" and "lock" assembly which plugs into the SD Card. To use, simply plug the "keylock" into the card slot and release the latch - the lock remains in place! Plug the key back into the lock to remove.
