Product Design using PXA270 Reference Design - Loyalty Card Terminal with Linux

Business Need

Whether it is a startup or an established business house, product along with the underlying business concept contributes most towards the success, as compared to other factor like customer segment, product cost, geography etc. Moreover if it is a debut product launch it proves to be a decisive factor i.e. make or break that too When product happens to be a cost-sensitive consumer device that will be manufactured by a contractor outside the United States, choosing a design partner can quickly turn into a bet-the-company decision.

That scenario was crucial for our customer, a Florida based startup preparing its first hardware Information Exchange Unit, a loyalty card reading terminal intended to realize the concept of bringing all the mom and pop stores under one umbrella, a single point Loyalty program.


In this case, for a cost effective solution, e-con system (Chennai, India) proved the right fit. Its work force of approximately 50 people in offshore development centre at Chennai having broad and deep expertise in Embedded Linux, Hardware Design, OS Porting, Firmware Development etc was matching to the skill set as required by the customer. Most importantly the customer was not interested in a fresh hardware design and was keener to have something ready made and go about customizing it. The PXA270 reference platform had most of the features the customer wanted but a few additions like a different LCD panel and IRDA. PXA270 reference design was customized based on the customer specific requirements and hence a fast solution.
