RFID Key Card Protector

youmagine

This case offers robust protection and durability for RFID key cards. It was created in response to a frequently used key card that kept breaking due to flexing when carried on a shared keyring. This protective case has proven its effectiveness over time, withstanding repeated use without issue. The key card remains functional within the case and is designed as a permanent addition to RFID key cards. Its design allows for continued use without removing it from the case. Specifically, this case was developed for RFID key cards with a particular shape factor, commonly found in brands such as Honeywell. These cards are typically the same size as a US driver's license, slightly tapered on one side for easy wallet storage, and feature a keyring hole at one end. If your key card matches this description, it is likely compatible with this design. However, if modifications are necessary to accommodate your specific key card, the source FreeCAD model is included for customization.
