Ingenico Bolt is a payment terminal that can be used to process credit card payments, while Odoo POS is a point-of-sale system that can be used to manage sales and inventory.

Ingenico Benelux is a specific region in Europe that uses different payment protocols than other regions, so it is possible that the Ingenico Bolt is not fully compatible with the Odoo POS system out of the box.

However, it is possible to make the Ingenico Bolt work with the Odoo POS system with a little bit of customization. Here are a few options you can consider:

1. Use a third-party module: There are third-party modules available on the Odoo app store or from other developers that may provide integration between the Ingenico Bolt and the Odoo POS system. You can search for these modules and check if they are compatible with your version of Odoo and your specific needs.

2. Custom development: If you have the technical resources, you can develop a custom module to integrate the Ingenico Bolt with the Odoo POS system. This will require a good understanding of the Odoo framework, and the specific requirements of the Ingenico Bolt.

3. Use a payment gateway: You can use a payment gateway that can process credit card payments and connect it to your Odoo POS system. This will allow you to use the Ingenico Bolt as a card reader and process the payments through the payment gateway.

It's worth noting that whichever option you choose, you should test it thoroughly and make sure it is secure and compliant with all the necessary regulations.

It's also good to check with your provider to see if they have any integration solution with odoo, or if they have any other recommendations.
