Last year we could process sales at conventions with a simple Point-Of-Sale -Software
that would keep the item-counts for the online-sales up-to-date.
It went much faster then using the shop-software with it’s long checkout-
process (at the table a delivery-adress or payment-method is meaningless).
This year we improved. We already have all the EAN13-barcodes for our products
in the database because many price-finder -websites make use of them.
Now we can use a barcode-scanner to speed up sales at the dealers-table too.
