Desktop RFID Card Reader/Writer, USB, 107 mm Square: overview
The PC-120 is a square USB desktop reader for card enrollment and encoding at front desks, security offices and membership counters. Its 107 × 107 × 24 mm footprint gives staff a generous target for presenting a card, and it runs driver-free from the host's 5 V USB port on Windows, Android and Linux.
Four versions cover the usual desk jobs. PC-120-E reads 125 kHz EM4100, EM4102 and EM4200-compatible cards and fobs, while PC-120-M reads 13.56 MHz UIDs from MIFARE Classic, DESFire, MIFARE Plus, Ultralight, NTAG2xx and CPU cards. PC-120-MS adds MIFARE Classic 1K/4K sector read/write and key changes through host software. PC-120-MS-N further supports CPU-card writing, DESFire EV1 application files and Ultralight/NTAG read/write.
Read-only versions send the card number in a format you configure in software, so it matches the numbering held in your access or attendance platform. PC-120-MS-N switches between active output and passive, command-driven operation, and its active output format can be configured too. Firmware updates are applied online.
Integration notes
Expect a read distance of 30 mm or more depending on the card and surroundings, with each read finishing in under 100 ms. Operating current is 150 mA or less. The reader is rated for −10 to +60 °C at 15–90% relative humidity. If you need a smaller rectangular unit with a metal frame or ICODE, iCLASS and FeliCa support, look at the PC-110 instead.

PC-120 FAQ
How does the PC-120 differ from the PC-110?
Up to the MS-N tier the card functions are the same. The PC-120 uses a 107 × 107 × 24 mm square housing, while the PC-110 measures 110 × 80 × 16.2 mm, has a metal middle frame and offers an extra ICODE/iCLASS/FeliCa tier.
Can the read-only versions write cards?
No. PC-120-E and PC-120-M only read card numbers. Choose PC-120-MS for MIFARE Classic sector writing, or PC-120-MS-N for CPU-card, DESFire EV1 file and NTAG writing.
Is a driver needed?
No. The reader is driver-free over USB, takes its 5 V supply from the port and works with Windows, Android and Linux hosts.
Does it read ICODE (ISO/IEC 15693) tags?
No PC-120 version lists ISO/IEC 15693 card support. Use the PC-110-MS-N-IC, PC-140 or PC-150 for ICODE tags.
How fast is a read?
A card inside the read distance is read in under 100 ms. Rated read speed is 0.2 s, with 0.5 s between consecutive reads.
