The ISO 15693 standard defines rules for short-range wireless communication, specifically for so-called "vicinity" cards. This technology works on the principle of RFID, which is radio frequency identification. Unlike magnetic cards, which require physical contact and swiping by a reader, communication according to ISO 15693 is contactless. The main characteristic of this standard is the greater reading distance, which is typically up to 1.5 metres. The reader generates an electromagnetic field that powers a passive chip in the card or tag, allowing it to send back stored data, such as a unique identification number. This feature makes the standard particularly useful in areas such as logistics for tracking goods, in library systems for bulk check-in of books, or in access control and asset accounting systems where items need to be identified from a distance and without having to be precisely attached to the reader.
