The Point of Sale interface is in beta. Currently, the only function of this interface is to archive tags which are read by a connected scanner in HID mode, such as a Keonn AdvanPay. Further integration with third-party point of sale software, such as Shopify and Square, is planned but not implemented yet.
#### Logging in Log in using the same credentials you use for the Simple RFID web portal and mobile app.  When you first log in, you'll be asked to select a location. Select the location where the scanner should be removing tags from.

You will need to scan items again if cleared accidentally. - ****View History**** - Press the ****History**** button to see all scans for the current location, including POS and mobile scans. - You can download reports from this page. - ****Change Location**** - Use the ****Admin Menu → Change Location**** to switch locations if moving the scanner between inventory areas. - The current location is also shown in the ****Location Indicator**** at the top. - ****Optional / Helpful Features**** - ****Help Button****: opens this guide in the knowledge base. - ****Theme Switcher****: toggle between Dark and Light mode. - ****Receiving Data Indicator****: shows when the scanner is sending data.

Help button [](https://kb.simplerfid.com/uploads/images/gallery/2025-12/xJwhelp.png) This button will bring you directly here to the knowledge base, where you can find instructions and relevant information about this app. ##### 2. Theme switcher Use this button to switch between Dark and Light mode. Functionality will remain exactly the same. ##### 3. Admin menu This menu contains two options: - ****Change location****: switch between locations. If you move the scanner between inventory locations, use this option. Otherwise, the location should remain the same. - ****Log out****: log out of your Simple RFID account. Note: you may choose to use a dedicated user account for the point of sale. ##### 4. Location indicator Appearing as part of the title, this simply indicates which location is currently selected, and where the tags will be archived in Simple RFID. ##### 5. Receiving Data indicator This indicator will appear when the app is receiving keystrokes from a Human Interface Device (HID). Most of the time, this will be the RFID scanner, but because your keyboard is also a HID, you'll also see this indicator if you press any keys.Any data that is not recognized as a valid EPC from an RFID tag will be discarded, so accidental key presses are usually not an issue. However, ****if you press any key(s) on your keyboard at the same time as scanning an RFID tag, you may need to re-scan the tag in order for it to register correctly.****
##### 6. Inactive indicator This shows when the app isn’t focused (meaning the app isn't the one you’re currently using). The scanner sends keystrokes like a keyboard, so the app must be open and active to get the input. Otherwise, the keystrokes will go wherever you’re currently working. ##### 7. Add/Remove switch This switch is labeled ****Add to cart / Remove from cart**** and lets you switch between adding items and removing them. For example, if you accidentally scan an extra item, switch to ****Remove from cart****, then scan that item again to remove it. Items need to be scanned again to remove them because we use the serial number from the EPC to make sure the correct items are checked out.Be sure to switch back to ****Add to cart**** before continuing to scan items!
##### 8. History button This button is a direct link to the Scan Sessions page for the currently selected location. This will display all scans that have occurred at this location, including point of sale scans and mobile scans. From here, you can download a report of any scan that has been submitted. ##### 9. Clear All button This button will clear all scanned tags from the current list. ****Proceed with caution: this cannot be undone, so the only way to add the tags back to the list is to scan them again.**** ##### 10. Checkout button This button will take the currently scanned tags, and submit them as an ****Archive**** scan to your inventory, removing all the tags from the active inventory. You will be asked to provide an optional comment, which will show up in your Scan Sessions history on the web portal. ##### 11. Scanned items This is a list of all known tags that have been scanned into the cart. The table displays the image (if one exists), the Title (Category | Name | Color | Size), and the Quantity that have been scanned. ##### 12. Unknown tags This is an expandable list of tags that were scanned, that were unable to be matched with a product from your library. You'll see the EPC of the tag, as well as the Company Prefix, Item Reference, and Serial Number decoded from the tag. This is mostly useful for troubleshooting purposes; these tags ****will not be included**** in the submitted scan session.
