Introduction
The ACR122U ACS Reader Writer is a PC-linked contactless smart card reader/writer developed on the 13.56 MHz contactless technology. It is the world’s first CCID-compliant contactless card reader/writer that follows both ISO 14443 and ISO 18092. ACR122U is also PC/SC-compliant which allows interoperability across different applications and platforms.
Both ACR122U Windows SDK and Android SDK are included in the software download with the purchase of ACR122U NFC writer.
Sample codes, utility programs, and ACR122U drivers are included. There are also user manuals to guide developers in building NFC-enabled and contactless smart card applications using the ACR122U NFC Reader Writer.
