Sihl – Security and protection for data content

GERMANY • Protective sleeves and envelopes made of Enduro Effect RFID shield by Sihl offer protection against unauthorised reading or manipulation of the data content.

In recent years transmission technologies have developed and are largely established on the contact- free transmission of personal data via RFID (Radio frequency identification) or NFC (Near-field communication). Data is transmitted and stored to a transponder, which can be read using a reader.

This process is used to read and verify a range of data, i.e.

  • ID cards
  • Entrance tickets or payment cards, used for access to public transport, ski resorts, leisure events, or similar
  • Credit or debit cards

All data stored on transponders is encrypted, but these codes can be decrypted, manipulated or simply made unreadable by means of electro-magnetic radiation.

Although all data is encrypted when stored in the transponders, ensuring a high level of security against abuse of the data, further security and protection possibilities are useful and are desired, both by the user and the provider of the RFID /NFC systems.

Enduro Effect 135 RFID shield 6821 is a compound material made of a shield core sandwiched between two layers of paper. According to Sihl, protective sleeves and envelopes made of Enduro Effect RFID shield offer protection against unauthorised reading or manipulation (via various commercial RFID or NFC frequencies) of data content.

The resonance circuit of the transponder is clearly shielded by the compound material, which reduces the reading range from a few centimetres to a few millimetres and distorts the frequency to such a degree that no data transmission is possible.

The frequency shielding product offers a variety of advantages: it is tear resistant and impermeable to water making it extremely hardwearing and durable. The high folding strength and excellent printability makes further processing possible.
