Contactless data storage medium |
| 摘要 |
A contactless data storage medium has at least two antennas, in each case for different transmission bands. This makes it possible to configure a data storage medium such that it can be operated with read/write units that operate in accordance with different standards. At least two of the antennas form a unit, so that a configuration such as this can be produced at very low cost.
