The primary function depends on your requirements. It is on the covert entry page of www.oscardelta.co.uk as it can be used for lock bypassing ‘carding’ a door; however, there are other technical uses…
The card is frosted allowing for you to place the card over printed text with the cut-out slot over the sensitive or private information. Using a black marker pen you then cover the text in black to redact the information from a document in preparation for publication. Ideally you should then photocopy the document and destroy the first copy to prevent recovery of the redacted text.
The LTX1 can also be used as a privacy screen for video calls on a mobile device. Simply place over the front camera to ‘blur’ your face/location. Light will still enter the sensor so the screen will remain on.
The LTX1 can also be used with Cavity Tray for The Ridge RFID Blocking Wallet, so you can easily load/unload the tray.
Audio jammers are popular tools used during confidential meetings. They produce a unique sound for masking and protecting conversations from external listening devices, such as a smartphone running an audio recording app, hidden in one of your guests’ pocket.
The sound of a jammer should be very difficult to filter out or remove when present in an audio recording. While commercial audio jammers often rely on white noise, this generator, however, uses a more efficient sound with articulation similar to speech. It is also buried under severe distortion, which makes recovery algorithms have a hard time producing exploitable results.
For further privacy, increase the generator’s volume to play louder than your voice. Then, if you are holding a conversation in person, speak quietly, and very close to your partner so they hear you over the sound.
