From GE Infrastructure, Security comes the Transition Series card readers. The readers are multi-vendor compatible with GE and HID Proximity cards, and with contactless smart cards that meet Mifare and Vicinity standards. The readers feature four-state supervision, which continuously monitor for cut line, short circuit, closed circuit, and open circuit conditions at door contacts and request-to-exit connections. If the reader is violated, an automatic internal tamper switch alerts security personnel. GE Infrastructure, Security
