The POS system can utilize system resources more effectively by employing the cache to store data. This also helps to reduce the hardware requirements for running the system,

In Odoo 16, you may use the ‘pos’ object to store values in the POS (Point of Sale) cache. The ‘pos’ object provides some methods for managing the cache. Here are some examples of how to store values in the pos cache using the ‘pos’ object

1. To store a value in the POS cache:

this.pos.get_order().order_note = 'Value';

2. We can retrieve the stored value from POS Cache using:

var note = this.pos.get_order().order_note;

3. We can store values for customers using:

this.pos.get_client().key_name = 'Key value';

4. We can retrieve the stored value from the customer:

 var value = this.pos.get_client().Key_name;

5. To store the value in the cache with the key :

var amount = 500.00;

this.pos.pos_cache.set('total_amount', amount);

6. To retrieve the stored value using the key:

var cachedTotalAmount = this.pos.pos_cache.get('amount');

7. To store value using the ‘cache’ object:

setCacheValue(key, value) {

this.env.pos.cache.put(key, value);


The ‘setCacheValue’ method is used to call the ‘put’ method of the ‘cache’ object to set the value for the key.

8. To retrieve value using the ‘cache’ object:

getCacheValue(key) {

Return this.env.pos.cache.get(key);


The ‘getCacheValue’ method calls the ‘get’ method of the ‘cache’ object to retrieve the value using the key.

The data kept in the POS cache is temporary and will be deleted when the POS session ends. If you want to store data permanently, you should need a server-side storage solution.
