Remarks

Required Version

The RFIDScanner class requires POS for .NET version 1.12 or later versions.

Capabilities

The RFID Scanner device has the following capabilities:

  • Reads TagID and UserData from RFID tags

  • Reads partial UserData

The RFID Scanner device may also support the following capabilities:

  • Continuously reads tags

  • Writes TagID to RFID tags

  • Locks a tag

  • Writes UserData to specified RFID tags

  • Disables (kills) RFID tags

  • Writes partial UserData

Programming Model

The RFID Scanner is both an event-driven input device and an output device. Input and output are always asynchronous. The tag is considered to consist of contiguous fields called the TagID and the UserData. This present standard does not currently define the TagID or UserData fields. They are determined in a device-specific manner by the RFID Scanner Service and may vary depending on the protocol property setting.

Device Sharing

The RFID Scanner is an exclusive-use device, as follows:

  • The application must claim the device before the application enables it.

  • The application must claim and enable the device before accessing many of the RFID Scanner-specific properties.

  • The application must claim and enable the device before it calls methods that manipulate the device.
