Online payment interface development

The purpose of our thesis was to present a short theoretical part of the online shopping and development of online payment and furthermore to present a system, which has been developed in our own company Idejanet d.o.o., where I am the sole owner and sole developer. The main purpose of our system is to offer the opportunity for smaller sellers and retailers who already sell items or wish to sell items in the online store, to expand the range of payment methods in their online store. Online stores lately tend to be the most user-friendly and accessible and that all of the procedures are as quick as possible. Online store is no longer just the domain of large retailers, so we approached the development of the interface and the system which would also allow smaller retailers or individual producers to offer popular payment options irrespective of whether they have their own system and are thus not linked to other intermediates (e.g. developing their own payment interfaces, contracting with payment processing provider, etc.). In practical part we presented the development and functioning of our system and payment interface that would allow a complete solution, which can be adapted to specific needs and business particularities of the provider through its online store. At the same time the system uses appropriate and the highest safety requirements and standards, since for many users security of payments and preventing abuse have even higher importance than the convenience of shopping.
