Connect Bar Code Scanners to Square Point of Sale

Learn how to connect and troubleshoot supported bar code scanners with the Square Point of Sale.

Supported Bar Code Scanners

USB Bar Code Scanners are supported on iPads through the Square Stand, the Square Register or selected Android devices. If you are using an Android, your device must be running Android 5.0 software and support USB OTG (On-The-Go) or host mode. You’ll need a micro USB to USB adaptor to connect the scanner to your device.

Scan a Bar Code From a Label Printing Scale

You are able to use label printing scales that support UPC-A and EAN-13 bar codes, such as the CAS CL 5500L or the Mettler Toledo bPro Terminal with Square Point of Sale. These scales measure the weight of an item and issue a bar code label that contains both an item stock-keeping unit (SKU) number as well as the total weight or price of an item. When items with these types of barcodes are scanned, the item’s weight and price information is automatically captured on your Point of Sale.

The format for UPC-A and EAN-13 barcodes is: 0-2AAAAA-BBBBB. It is important to note:

  • The first five digits of the barcode (i.e. AAAAA) is an item code that maps the SKU entered in for an item on the point of sale. For example, if your item code is “00123”, this portion of the bar code will also read “00123”.

  • The last 5 digits of the bar code (i.e. BBBBB) represent the total price of an item in cents. Thus, an item that is $12.34 would read as 01234. This value is used to calculate weight, with the minimum value being $0.01 and the maximum value being $999.99.

  • The first digit of this bar code will be “0” for EAN-13, except for UPC-A in which case the “0” is not required. The second digit will always be “2”.

This compatibility is only available for iOS devices at this time.

Note: It is recommended that SKUs for UPC items are not matching number subsets of existing items. For example, item A has a SKU of 021234500999 and item B has a SKU of 12345 with a bar code label of 021234500999. When item B is scanned, the barcode price will be mapped to item A and not item B.
