| **Items scanned and put in the sales cart and then disappear from the cart** | No Negative Quantity is enabled | If they want to disregard what quantity is in the system and sell it even if the quantity is not a positive #, then disable this function on the TabPOS configuration. |
| **Bar code scanner is beeping but not taking any barcodes.(Elo)** | Elo Settings configuration | Go to home --> swipe and navigate to configuration 2. Click hardware tab 3. Click devices from let section 4. Make sure Elo is selected. Navigate back to home screen . Logout and login back and try again. |
| **"All Items" button missing on Quick Picks** | Once your item list reaches 100 items, the software is designed to omit the "All Items" tab for the reason it would take quite a bit of loading time to display over 100 items. | If there are items which are not represented within your Quick Picks, you can use the search field (represented by the magnifying glass) to find those items by name. |
| **Unable to update the customer details while doing sale transaction** | | Modify the last customer ID on CAS to a lower #, so that the tablet customer ID is unique |
| **Unable to pair PAX EMV reader with tablet** | | Check :
- Is the tablet connected to the internet, pull up a site from your browser to verify.
- Verify that the IP address is "Standard" to pair it with the Tablet. Should be in the normal format, such as 192.168.001.139
- Verify that the IP address is entered in the tablet without lead zeros. If the IP address in the Pax is 192.168.001.139 enter it as 192.168.1.139 (followed by the port )
- It would be entered as (Ex: 192.168.1.139:10009)
- The Application in the PAX should have a https Get Command for communicating with the Tablet (this is set up by your processing company)
