USB Data Blockers are a handy and increasingly important device that help to keep your clients safe when charging their devices in public. Public USB ports are being increasingly targeted in public by hackers, who can use them to gain access to your device, capture their data and passwords, and even use screen-capturing software to watch actions. Branded Data Blockers prevent this by not allowing any data transaction to take place, only power itself. Not only does this make them an incredibly useful product, but also a great promotional branding opportunity. Available in a clean white finish, these compact devices can be branded using full-colour print. UK stock.
