The PRX M motor-driven reader is a special reader designed to retrieve business cards, when leaving visitors, preventing them from leaving the establishment with the card. Unlike with the single and double mailbox readers, the motorized system allows its installation in posts at 90º thanks to its electromechanical mechanism automatically introduces and ejects the cards. The PRX M motor-driven card reader includes a 13.56 MHz Mifare® card reader, with read/write capability that allows the use of encrypted Mifare® sectors to store the card's serial number, avoiding use of the CSN of the card as it is not protected and insecure. Thanks also to the ability to read / write, the PRX M motor-driven reader also allows the use of DOC SYNC™ technology for the integration of autonomous equipment.
