The 1840-5084 is an RFID-blocking credit card sleeve that blocks radio frequency signals from reaching credentials stored inside. Constructed from tear-proof, water-resistant paper with embedded metallic shielding, each sleeve accepts standard credit-card-size inserts measuring 3.38" x 2.13" (86 x 54mm) within an outside sleeve dimension of 3.50" x 2.13" (89 x 54mm). The multi-directional opening allows cards to slide in from either end.

The embedded metallic barrier blocks RFID skimming attempts from electronic readers. Cards remain easy to access when needed while staying protected from unauthorized electronic reads when stored inside the sleeve. Simply slide the card out of the sleeve when you need it read by an authorized terminal, then return it to block all signals again.

Banks, financial institutions, government agencies, and corporate travel programs issue these sleeves to protect employee and customer credentials from electronic data theft in public spaces. Healthcare organizations use them to protect smart ID cards and access badges. IT security teams and loss prevention departments use them to protect RFID-enabled credit cards, CAC cards, and e-passports across large workforces. The blank exterior surface accommodates custom printing for organizations that want to add branding or usage instructions to the sleeve face. USA made and GSA approved.
