We engaged Pretech to develop a softPOS Android tablet for a startup in mobile payments. From the first technical spec to shipment, Pretech handled custom hardware, NFC firmware tuning, security module integration (eSE), and driver-level optimization. Their engineers simulated worst-case interference scenarios and ensured stable NFC operations. The initial batch of devices passed PCI certification, and our app works flawlessly in real stores. Pretech is a very trustworthy OEM/ODM supplier in the NFC tablet field.
