Hybrid cards have multiple chips in the same card. These are typically attached to each interface separately, such as a MIFARE chip and antenna with a contact 7816 chip in the same card.
Dual Interface Cards
These cards have one chip controlling the communication interfaces. The chip may be attached to the embedded antenna through a hard connection, inductive method or with a flexible bump mechanism.
Multi-component Cards
These types of cards are for a specific market solution. For example, there are cards where the fingerprint sensor is built on the card. Or one company has built a card that generates a one-time password and displays the data for use with an online banking application. Vault cards have rewriteable magnetic stripes. Each of these technologies is specific to a particular vendor and is typically patented.
Smart Card Form Factors
The expected shape for cards is often referred to as CR80. Banking and ID cards are governed by the ISO 7810 specification. But this shape is not the only form factor that cards are deployed in. Specialty shaped cutouts of cards with modules and/or antennas are being used around the world. The most common shapes are SIM. SD and MicroSD cards can now be deployed with the strength of smart card chips. USB flash drive tokens are also available that leverage the same technology of a card in a different form factor.
