SIP is the standard interface protocol that is supported by many vendors for library circulation. It was developed originally to support the 3M SelfCheck System, which allows library users to check their materials in and out themselves. We developed SIP to be a common protocol, published it as a public, open standard, and encouraged library automation vendors to use it in an effort to promote interoperability.
At 3M, standards are pervasive in everything we do. The factory where our products are made is ISO 9000 certified. We use test standards extensively to ensure safety and product quality. For example, we test our RFID products as a system for electromagnetic compatibility to prevent interference and to meet FCC regulations. We even have a special department at 3M to guide developers through their testing of products. We know both durability and longevity are important and we do accelerated aging tests in our specialized laboratory so our customers can have confidence that our RFID tags will be reliable and will last as long as the items to which they are attached.
