Cards & Readers
When you swipe a magnetic-stripe card, the technology transmits the bank info to the card reader, which sends it to Square. We then pass along that information to the acquiring bank. Square's magstripe reader plugs into your iOS or Android device's headset jack so you can take credit card payments anywhere.
A pedestrain barrier is a component which prevents passage into a dangerous area, commonly used to mitigate risk. Safety barriers may be hard barriers physically restricting passage or soft barriers that control circuits based on the presence of foreign bodies.
A turnstile, also called a baffle gate or turnstyle, is a form of gate which allows one person to pass at a time. It can also be made so as to enforce one-way traffic of people, and in addition, it can restrict passage only to people who insert a coin, a ticket, a pass, or similar.
