The tank of a wall-mounted toilet is inside the wall behind it, so it uses the depth of the wall to reduce how far it protrudes into the room. For the carrier system inside the wall, you can get one that either fits into a wall with 2-by-6-inch studs or one that recesses into a wall with standard 2-by-4 studs. This is an example of a contemporary bathroom in New York.
Payment Card Industry Data Security Standard. The Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle branded credit cards from the major card schemes including Visa, MasterCard, American Express, Discover, and JCB.
Payment Card Industry Data Security Standards (PCI DSS) are designed to provide merchants a single set of requirements for safeguarding sensitive data. These standards have been adopted by all the card brands in conjunction with the PCI DSS. The standards require that all merchants (regardless of their size or type of payment system) that store, process, transmit or have access to cardholder data must be in compliance to protect that data.
