The RFID-B1-USB from ECCEL is an integrated RFID reader and antenna designed for use in applications such as contactless payment systems, access control, and asset tracking. The reader antenna measures 94x37.5mm, and consists of an RFID transceiver with an ADC, GPIO, PWM, UART and USB interface, powered by a 4.5÷5.5V supply. The device is capable of reading most common RFID tags, such as Low Frequency (LF), High Frequency (HF) ISO14443 and NFC tags. The USB port allows for the reader to be connected to a host computer, allowing for the setting of parameters, tag data transfer, and remote radio frequency identification (RFID) checks.
