To reset your Ingenico ISC 250 touch or ISC 350 terminals, hold down the minus and yellow clear button at the same time. Unplugging the terminal and replugging while connected to a power source is not recommended and doing so may corrupt the pin debit key, requiring a new key encryption injection.
3D Merchant Services provides payment processing technology for merchants to run Ingenico and other signature capture terminals, without specialized POS software. The credit card processing terminals can be operated with our secure virtual terminal or with integrated solutions that can keep merchant POS applications out of scope for PA DSS. Many recent merchant data breaches have occurred from applications that were in scope for PA DSS. By segregating payments from POS applications, merchants can increase security while reducing compliance burden.
