SPIn-Enabled Terminals Now Support Dynamic Cart Updates

The SPIn Display Cart Items API now supports real-time cart updates on the terminal. POS systems can send items to the terminal one at a time or all at once, allowing customers to see their cart as it’s being updated—right on the SPIn-connected Dejavoo terminal. The terminal will stay in listening mode whenever a line item request is sent, ensuring the items in the cart update automatically whenever it receives a request from the POS system.

This enhancement enables a more interactive and transparent checkout experience.
