1. Introduction
The ACM1252U-Y3 is a versatile USB NFC reader module designed for rapid integration into embedded systems, leveraging advanced 13.56 MHz contactless technology. Building on the success of its predecessor (the NFC Forum-certified ACR1252U-A1), this module supports all three NFC modes—card reader/writer, card emulation, and peer-to-peer communication—making it ideal for secure transactions in vending machines, kiosks, gaming systems, and industrial applications.
