EZVIZ Proximity Card RFID Access Key for Smart Locks & Doorphones
The EZVIZ CPU Proximity Card (CS-DL-IC-CPU-R200) is a contactless key tag for EZVIZ smart door locks and EZVIZ smart video doorphones. You hold it close to the reader to unlock, without a code or a phone. It comes in a pack of 4 grey tags, each 40 × 32 × 3.7 mm.


Contactless unlocking: The tag works at an operating frequency of 13.8–14.4 MHz and only needs to be held near the reader. It gives a quick way in without typing a passcode.
Encrypted CPU card: The card uses EZVIZ's own encryption algorithm with chip authentication to protect the data stored on it, which EZVIZ designed to prevent the card from being copied.
Pack of 4 tags: Four tags let you give a key to several members of the household or keep one as a spare. The key-fob shape has a hole for a key ring.
Who it's for / Works with
EZVIZ smart door locks and EZVIZ smart home video doorphones (such as the HP7 2K) that support proximity cards. Check that your lock or doorphone model supports card unlocking before buying.
