Rewritable EM ID 125KHz White Card with EM4305 Chip for Access Control

Rewritable EM ID 125KHz white card with EM4305 chip, PVC material, dimensions 85.6x54x0.88mm, blank white color, 125KHz frequency, EM4305 chip with 512-bit EEPROM and 32-bit UID, ISO 11784/11785 compliant.

The RFID card contains a small chip and an induction loop that the transmitter on the card reader can access. The main advantage of RFID cards is that they do not need to be taken out of a wallet or pass holder — card readers can typically read from a distance of a few inches.

Blank Unprinted Card

There is no printed content on the white card. Many customers order large quantities of blank cards and print them themselves with a printer to save costs. A laminated coated overlay should usually be added to the white card so customers can print on it.
