TWR Pro is revolutionary and innovative product, based on 13.56 MHz RFID and 433 MHz wireless technology. These relatively well known technologies are combined with D-logic's genuine Low Power Consumption fundamentals. D-Logic – Low Power Consumption (DL-LPC) is a result of 2 year long research conducted at our R&D labs. After thorough research and lot of testing, finally we got unexpectedly good results regarding devices power consumption. Based on that result, we made TWR Pro, unique product among all other RFID readers worldwide. TWR is acronym for Total Wireless Reader; Pro stands for Professionals, for whom it is primarily intended. It comes as a set with all needed resources, including additional Reader/Writer for MIFARE® card programming, set of cards for testing, well documented SDK API and DLL, demo software with examples and source-code for several programming languages like Delphi, Lazarus, C/C++. Regular updates and improvements of firmware and documentation can be obtained absolutely free from download section at our site. TWR Pro can read MIFARE® ISO 14443 type-A proximity cards and tags. It can read MIFARE® unique CSN (4-byte or 7-byte) only, or user defined data like cardholder number and system ID's. Card blacklisting feature is also avaliable as a standard option. TWR Pro incorporates 48-bit standard MIFARE® keys with special security keys to provide better security.


Technology Brief

TWR Pro is set of two paired hardware devices: a Card Reader and RF transceiver. Card Reader device is contactless RFID Reader intended for all passive ISO14443 A-type MIFARE® cards and tags. Maximum card reading range is up to 4 cm (approx. 1.5 “) from Reader's surface. It uses 433 MHz wireless technology platform to transmit all card related data and device status data to RF transceiver. Due to our Low Power Consumption technology, we can provide enough power for Readers everyday regular operations with only one battery pack. According to our lab and on-field testing results, one battery pack has enough capacity to provide 1,000,000 (1 Million) card reading cycles. Also, it can work in stand-by mode for 10 years or it can give one Full-dump Log package (64KB) package per day for next 80 years! Reader can be mounted as indoor or as outdoor device, with the use of special housing. Reader has it's paired device, a small and clever RF transceiver which can be connected to PC's USB port. Reader and RF transceiver communicate with each other by dedicated wireless link established on a frequency of 433 MHz. It also incorporates separate channel groups, which are good way to avoid collisions or "RF pollution". NO external power is needed. Known limitations of USB cable length can be override by RS-485 RF transceiver module, if needed. This is exception from common installation practice, since that type of topology needs some cabling, but is also good way to override longer distances and get closer to reader's area due to some specific site installation demands.
