Touch Memory Card (TM Card) is a storage medium invented by Dallas Company in the United States. It adopts single line protocol communication technology and allows users to complete data read and write operations through simple instant touch. The TM card combines the ease of operation of non-contact IC cards with the low-cost advantages of contact IC cards, and is considered one of the IC cards with high cost-effectiveness. Although it is no longer an exclusive patent of Dallas, domestic brands such as LIY are still producing similar products. The TM card is compact in size and can be embedded in various objects, such as cards, keychains, etc. Its integrated circuit chip is sealed in a stainless steel shell, which has waterproof, shockproof, and anti-corrosion characteristics.
The basic characteristics of TM cards reflect a series of advantages in their design and manufacturing. Firstly, the TM card adopts single line protocol communication technology, which means that users can complete data reading and writing operations with just a simple touch. This design simplifies the usage process and improves the user experience. Secondly, TM cards combine the advantages of non-contact IC cards and contact IC cards, combining ease of operation and low cost. This makes TM cards a cost-effective IC card suitable for various application scenarios.
The size of the TM card is very small and can be easily embedded into various objects. The integrated circuit chip is encapsulated in a stainless steel shell, endowing the TM card with waterproof, shockproof, and corrosion-resistant characteristics. This design enables the TM card to operate stably in various harsh environments, expanding its application range.
