Abstract: An introduction system for making new friends and/or dating without time limits, potentially throughout life, easily, inexpensively and even unexpectedly, in which anyone can try to attract anyone they encounter entirely by chance or otherwise, immediately or subsequently into an introduction process, using a ring and/or other device. The ring/other device has a logo and/or is otherwise distinctive in appearance and/or design and is used as a ‘people magnet’ to effect entry into the introduction process. Flash cards/other devices may be used in this process to help determine compatibility, to help terminate unsuitable introductions very quickly and/or to provide other information, including contact details of a centralized administrative agency that may be established to facilitate introductions and to publicize, develop and market the system and related merchandise.
