Read and/or write operations between the probe and memory chip are performed with just a momentary contact. Thousands of reads and writes can be performed with a single chip and data integrity can last over 100 years.
Touch memory complements such technologies as bar codes, RFID tags, magnetic stripe, proximity cards and smart cards.
