License Model

Introduction

The ItemEncode licensing model is a consumption-based model that tracks volume of tag encoding operations executed by the ItemEncode system. Users purchase a Volume License Key for a set volume/number of encoding operations and apply this key to their ItemEncode devices. The key unlocks the ItemEncode system to encode Monza or non-Monza tags. The Volume License Key is a one time use key that is sent to the ItemEncode device to increase the count of remaining encode volume.

In addition to the Volume License Key, all ItemEncode devices must have the appropriate Speedway Feature Key installed.

Speedway Feature Keys

ItemEncode uses Speedway Feature Keys to enable basic device operation depending on what is required for the system. To acquire a Speedway Feature Key, please contact Impinj Support with the serial numbers of the devices requiring the key.

• ItemEncodeMonza - This Feature Key enables the ability to encode supported Impinj Monza tags. It must be installed on all ItemEncode devices in the system.
• ItemEncodeNonMonza - This Feature Key enables the ability to encode supported non-Monza tags. It must be installed on all ItemEncode devices in the system.

Note

The installation of Speedway Feature Keys is documented in the RShell Reference Manual

Volume License Keys

The ItemEncode Volume License Key is a one time use key that increases the volume of tags ItemEncode can attempt to encode. End users can purchase these keys from Impinj. Separate keys are available for Monza and non-Monza tag encodes. When the key is applied to the ItemEncode system, it will add to the existing volume of encodes. When ItemEncode attempts to encode a tag, it will decrement an encode from the volume of encodes available in the ItemEncode system. When the volume of encodes available on the system reaches zero, the ItemEncode device will no longer be able to encode tags.

Volume Management in a Pipeline System

In an ItemEncode Pipeline System, the same tag could be encoded by multiple devices. To keep the ItemEncode devices in sync with each other, the remaining volume is tracked on only one device. This device is referred to as the Device of Record. It can be either an encoder or verifier. The other encoders in the Pipeline System will need to be configured to communicate with the Device of Record. For more information on how to configure the Device of Record in a Pipeline System, please see Configuring the Device Of Record.

Note

While only the Device of Record requires a Volume License Key in a Pipeline System, all devices in the system will still require the Speedway Feature Keys.

Volume License Key Activation

Unlike the Speedway Feature Keys, the Volume License Keys are activated using the ItemEncode API. For more information on how to activate Volume License Keys, please see Activating Volume License Keys in the API Guide.

Volume Monitoring

There are two ways in which to monitor the remaining volume. At any point, the ItemEncode device may be queried for the OperationData. This object will contain the remaining volume of encodes for both Monza and non-Monza tags. In addition, the ItemEncode device can generate a LowEncodeVolumeEvent when the remaining volume passes below a certain threshold. For more information on monitoring remaining volume, please see Monitoring Remaining Volume in the API Guide.

Volume Decrementing Exceptions

There are some exceptions to decrementing the remaining Monza or non-Monza encoding volume. In scenarios where ItemEncode can determine that no encoding is taking place, the volume will not be decremented. The following TagOperationResult values correspond to these exceptions:

• TAG_OPERATION_RESULT_PASS_ALREADY_DONE
• TAG_OPERATION_RESULT_RETRY
• TAG_OPERATION_RESULT_RETRY_INSUFFICIENT_POWER
• TAG_OPERATION_RESULT_RETRY_NO_RESPONSE_FROM_TAG
• TAG_OPERATION_RESULT_RETRY_SERIALIZATION_JOB_QUEUE_EMPTY
• TAG_OPERATION_RESULT_RETRY_TID_TABLE_NO_MATCH
• TAG_OPERATION_RESULT_RETRY_ORDERED_LIST_EMPTY
• TAG_OPERATION_RESULT_FAIL_SERIALIZATION_JOB_QUEUE_EMPTY
• TAG_OPERATION_RESULT_FAIL_TID_TABLE_NO_MATCH
• TAG_OPERATION_RESULT_FAIL_ORDERED_LIST_EMPTY
• TAG_OPERATION_RESULT_FAIL_TAG_CHIP_NOT_SUPPORTED
• TAG_OPERATION_RESULT_FAIL_TAG_CHIP_SUPPORTED_LICENSE_KEY_NOT_INSTALLED
• TAG_OPERATION_RESULT_FAIL_TAG_NOT_INVENTORIED
• TAG_OPERATION_RESULT_FAIL_VOLUME_EXHAUSTED
• TAG_OPERATION_RESULT_FAIL_SERIAL_NUMBER_RANGE_EMPTY
• TAG_OPERATION_RESULT_FAIL_VOYANTIC_TEST_RESULT_MISSING
• TAG_OPERATION_RESULT_FAIL_VOYANTIC_TEST_RESULT_FAILED
• TAG_OPERATION_RESULT_FAIL_TID_TABLE_INVALID_CONFIG
• TAG_OPERATION_RESULT_FAIL_FILTER_NO_MATCH
• TAG_OPERATION_RESULT_FAIL_VOLUME_LICENSE_REVOKED
