Patent attributes
Introduced is a technology for processing transactions on behalf of a merchant employing a legacy system, where the processing includes managing inventory data and bundle pricing data associated with transactions occurring at various point-of-sale (POS) devices that include both legacy and non-legacy POS devices. Briefly described, the technology involves a payment processing system (PPS) working in coordination with a legacy merchant system. The PPS includes a payment processing database system, a adapter module installed at the merchant system, and a payment processing engine installed at a cloud-based server system. The payment processing engine, via the adapter module, can receive the most up-to-date inventory data and bundle pricing rules from the legacy merchant system. Based on the bundle pricing rules, the payment processing engine can compute one or more minimum-price carts that apply pricing discounts to eligible items for transactions occurring at the POS device(s) associated with the PPS.
