The ACR122S NFC Contactless Smart Card Reader is the serial interface reader in the ACR122 family developed based on the 13.56 MHz Contactless (RFID) Technology and compliant with the ISO/IEC 18092 Standard for Near Field Communication (NFC). It supports for Mifare， ISO 14443 Type A and B， FeliCa and NFC cards and devices， including all three NFC modes (reader， card emulation and peer-to-peer) and four types of NFC tags.<br>ACR122S is a plug and play device which does not require any driver installation. It comes with a built-in ISO 7816 SAM slot for enhanced security， plus a buzzer and two LEDs for rich user interaction. The reader can also read and write faster and more efficiently by making use of up to 424 Kbps for tag access. The proximity operating distance of ACR122S is up to 5cm， depending on the type of tag in use.<br>ACR122S is also available in module form for easy integration into bigger machines， like physical access devices and vending machines.<br><br><strong>Features:</strong><br>Serial RS-232 Interface: Baud Rate = 115200 bps， 8-N-1.<br>USB interface for power supply.<br>CCID-like frame format (Binary format).<br>Read/write speed up to 424 kbps.<br>Built-in antenna for contactless tag access， with reading distance of up to 50mm(depending on tag type).<br>Support for ISO 14443 Part 4 Type A and B cards， Mifare， FeliCa， and all four types of NFC (ISO/IEC 18092 tags).<br>Built-in anti-collision feature.<br>ISO 7816-compliant SAM slot. ?<br>Two user-controllable LEDs.<br>User-controllable buzzer.<br><br><strong>Applications:</strong><br>Vending Machines;<br>Public Transportation Terminals;<br>Customer Loyalty;<br>Time and Attendance;<br>Contactless Public Phones;<br>Network Security;<br>Access Control;<br>Physical Access Control， etc.<br><br><strong>Installation of Testing Software:</strong><br>https://www.dropbox.com/s/zog2ssym1aq07up/S368.zip?dl=0?<br><br><strong>Specifications:</strong><br>Interface: RS232 for data communication， USB for power transmission<br>Operating Distance: Up to 50mm (depends on the tag type)<br>Supply Voltage: Regulated 5V DC<br>Supply Current: 200mA(operating); 50mA(standby); 100mA(normal)<br>Operating Temperature: 0~50°C<br>Operating Frequency: 13.56 MHz<br>Smart Card Interface Support: ISO14443 Type A !#!amp!*!
