Depending on business tasks, a different level of integration of cash register software with Loymax processing is required.

• The minimum level implies the presence of the minimum necessary set of functionality for working with Loymax processing. For example, the ability to read the barcode of a card to identify a customer, send processing requests to get a card balance, calculate discounts, print messages received from processing on a cheque and cash register screen, and use an electronic digital signature.
• The middle level includes more ways to identify the customer at the cash register, identification and printing of coupons in the form of barcodes, the ability to work offline.
• The maximum level covers all the features implemented on the processing side. For example, registration, card issuance and redemption of an online order at the cash register.
