FAQs – RFID Sleeves & Envelopes


What is RFID?

RFID, or radio frequency identification, is the technology that lets you simply wave your credit card, passport or license in front of a nearby scanner instead of having to slide the magnetic stripe through it.

The electronic scanner sends a signal which is received by an antenna embedded into the card, which is connected to the card’s RFID chip, thus activating it.

The RFID chip in these cards emits all of the information, including the account number that is needed to complete a transaction.

Why is there a need for RFID shielding for credit cards?

About 100 million credit cards in North America now have RFID technology embedded into them. However, over the next two to three years, credit card issuers plan to replace every single magnetic stripe credit and debit card with a new contactless smartcard.

These cards can be read without even taking them out of your wallet. The RFID shielding technology in our ArmorShield™ card sleeves blocks this transmission from happening as long as the card is inside the sleeve.

This technology will also be incorporated into Debit Cards and Passports in Canada.


What is skimming?

Skimming is the process where “thieves” record your personal information from your card without your knowledge.

This technology is relatively easy to acquire and is so unobtrusive, you would never know it has happened.

What is ArmorShield™?

Exclusive to our supplier, ArmorShield™ is a unique material used to make our Secure Sleeve™ which protects smart cards and contactless cards from being read without your knowledge.

ArmorShield™ is durable and resistant to tears, punctures, moisture and chemicals, and provides shielding for ISO 14443/15693 and EPC Gen 1/Gen 2 contactless smart card and any contactless card that operates at 13.56 MHz and above.

Secure Sleeve™ effectively blocks the ability to read a RFID encoded card. The Secure Sleeve™ made from ArmorShield™ is FIPS 201 approved by the U.S. Government as an electromagnetically opaque shield.

It is also used by NEXUS and the BC Motor Vehicle enhanced driver’s licences.

cards and gift cards where the card will be used and the sleeve will not 
be used again.
