PAC ISO Printable Proximity Card - 10 Pack. PAC ISO Card offers a low cost solution with all the benefits of PAC technology. To identify your card simply look at the bottom right corner of the card, you should see a diagonal row of black dots. As an alternative to the traditional mechanical key, PAC’s proximity ID devices are used by millions of people as an easy and reliable means of gaining access to their places of work and other secured access points e.g. carpark barriers and turnstiles. The PAC ISO proximity card is a truly 'credit card' thin access ID device, and is ISO 7813 compliant with a nominal thickness of 0.76 mm. The ISO is also available with a magnetic stripe for use with other systems, such as cafeteria vending, copy machines and fuel dispensing. Digital photos and graphics can be printed directly over the ISO's front surface by using an ID card printer. Bar codes may also be imaged onto the card for systems tracking time-and-attendance for job costing.
