About ā A metal housed keypad and proximity reader primarily for external use. It reads MIFARE 1kĀ®, MIFARE 4kĀ®, MIFARE UltralightĀ®, MIFARE Ultralight CĀ®, MIFAREĀ® DESFireĀ® and MIFAREĀ® DESFireĀ® EV1 tokens. Installation ā The reader is wired as shown on the control unit label. The cable exits centrally from the back of the reader making drilling and mounting very accurate. Operation ā A token is read by holding it within close proximity of the reader. Once a token has been read if the reader has been configured for code/PIN this must then be entered using the keypad. The control unit verifies the information and grants or denies access as appropriate. If access is granted the green LED flashes. If access is denied the red LED flashes. *MIFAREĀ®, MIFAREĀ® Plus, MIFAREĀ® Ultralight and MIFAREĀ® DESFireĀ® are registered trademarks of NXP B.V. and are used under license.
