# Add Value In Encrypted Rate

## How to Add a Value to the Encrypted Rate in Barcode Label Printing?
In this tutorial, we will learn how to use the **"Add Value in Encrypted Rate"** feature in Logic ERP to add an additional encrypted value to the rate displayed on barcode labels, providing an extra layer of security for rate information.
***
### Objective of This Feature
* Add an additional value to encrypted rates
* Enhance rate confidentiality
* Encrypt numeric values into alphabets
* Replace characters within the encrypted rate
* Improve security of rate information on barcode labels
***
### Observe the Default Rate Display
* Navigate to the **Barcode Label Printing** module.
* Select the required **Purchase Voucher**.
* Select the required item and click **Create**.
* In the Barcode Printing Design Selection window, click **No**.
* Click **Open** and select the required barcode design.
**Result**
The rate is displayed in its **normal numeric format without encryption**.
***
### Configure Number-to-Alphabet Mapping
* Open the **Assign Alphabets to Number** module.
* Numbers from **0 to 9** are displayed in the Number column.
* Assign a unique alphabet against each number.
* Save the configuration.
**Note**
This mapping is used to convert numeric rate values into their encrypted alphabet format during barcode printing.
***
### Enable Rate Encryption
* Return to the **Barcode Label Printing** module.
* Open the configuration.
* Navigate to the **Display Encrypted** section.
* Select the rate field for encryption.
**Example**
* Select **MRP** as the rate field.
* Now print the barcode without configuring **Add Value in Encrypted Rate**.
**Result**
* The MRP is displayed in its **encrypted format**, without any additional value being added.
***
### Configure "Add Value in Encrypted Rate"
* Return to the **Barcode Label Printing Configuration**.
* Locate the option labeled as:
> **"Add Value In Encrypted Rate"**
* Enter the required numeric value.
* Save the configuration.
**How It Works**
* The numeric value entered here is converted into alphabets according to the **Assign Alphabets to Number** mapping.
* The encrypted value is then added to the end of the encrypted rate, **replacing the same number of characters**.
***
### Verify the Encrypted Rate
* Select the same **Purchase Voucher**.
* Open the barcode design.
* Preview the barcode label.
**Result**
The configured value is successfully encrypted and added to the **encrypted MRP** on the barcode label.
***
### Key Benefits
* **Enhanced Security:** Adds an additional layer of protection to encrypted rates.
* **Rate Confidentiality:** Makes actual rate information difficult to interpret.
* **Custom Encryption:** Allows users to define the value to be added.
* **Alphabet Mapping:** Converts numeric values into configured alphabets.
* **Secure Barcode Labels:** Provides greater control over rate information displayed on labels.
***
### Important Note
The **"Add Value in Encrypted Rate"** feature works with the number-to-alphabet mapping defined in the **Assign Alphabets to Number** module. The entered numeric value is encrypted according to this mapping before being added to the encrypted rate.
***
### Final Outcome
After enabling **"Add Value in Encrypted Rate"**, Logic ERP encrypts the configured numeric value and adds it to the encrypted rate displayed on the barcode label, providing an additional layer of security for rate information.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/reports-queries/item-report/barcode-labels-printing/barcode-labels-printing-configuration/add-value-in-encrypted-rate.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
