ACR122U Software Development Kit SDK

The ACR122U is a USB NFC reader that supports contactless smart cards and tags based on the 13.56 MHz frequency. It is compliant with the CCID specification and can be used for various NFC applications, such as e-payment, access control, personal identity verification, mass transit and toll road fare collection. The ACR122U also supports peer-to-peer communication and card emulation modes, making it a versatile and powerful NFC device.

To help software developers integrate the ACR122U into their applications, ACS provides a comprehensive Software Development Kit (SDK) that includes sample codes, tools, documentation and drivers. The SDK supports various programming languages, such as Java, Delphi, Visual Basic, Visual C++, Visual Cand Visual Basic .Net. The SDK also provides a simulation of a real-world NFC peer-to-peer application, called Smart Poster, that demonstrates how two ACR122U devices can exchange data via NFC.

Applications of the ACR122U SDK

The ACR122U SDK can be used for developing various NFC-based solutions, such as:

E-payment: The ACR122U can be used as a payment terminal that accepts contactless cards or NFC-enabled mobile phones as payment methods.

Access control: The ACR122U can be used as an access control device that grants or denies access to authorized users based on their contactless cards or NFC-enabled mobile phones.

Personal identity verification: The ACR122U can be used as a personal identity verification device that authenticates users based on their contactless cards or NFC-enabled mobile phones.

Mass transit and toll road fare collection: The ACR122U can be used as a fare collection device that deducts fares from contactless cards or NFC-enabled mobile phones when users enter or exit public transportation or toll roads.

Smart Poster: The ACR122U can be used as a smart card poster that displays information or advertisements on its LCD screen and allows users to interact with it using their NFC-enabled mobile phones.
