Basic validation methods are easy to use for small businesses and they don't require an advanced POS setup with barcodes.


# Advanced POS integration with barcodes. 


### A) Generate unique barcodes in your POS platform and let Coupontools display a unique barcode on each coupon.
 
How does it work? The existing POS system generates a batch of for example 100 000 unique barcodes. You are able to import those barcode values for a coupon and setup your preferred barcode format. Our platform will random use those barcodes and display a unique barcode on each coupon. The POS recognizes if the barcode is unique and valid.

### B) Setup a fixed barcode value
If your POS platform cannot create unique barcode values you can setup a fixed barcode value in the coupon. Coupontools will display the same barcode for every user.
Advantage: it's scannable with the POS barcode scanner
Disadvantage: because every coupon has a identical barcode you cannot prevent fraud and cannot track back the barcode to the user.


### C) Integrate your POS platform with our API.
We offer and API + webhooks to create a seamless integration with any internet enabled POS platform. The POS system needs to create an integration with our API. There might be extra costs involved.
