This badge holder is strong, because it is made by rigid polycarbonate PC plastic material. Color is transparent clear so the neutral color works well with the work ID cards. Core part is covered by RFID safe material. So the contactless card (13.56 Mhz standard) can´t be read unless removed from the badge holder. To other side of the ID holder you can insert and remove your card from the top and to other side you and insert and remove the card sliding from the side. If needed, you can slide your card about halfway out easily with one hand when you present your card door reader.
This RFID safe badge holder is tested and approved (11/6/2018) by GSA FIPS 201 for using with HSPD 12 PIV credentials which are usually named for example CAC card, TWIC card, LincPass, Smart Card or Fed ID card as Federal Identity Credential.
