Also known as NFCA.
Based on ISO14443 standards.
Near Field Communication devices implement native support for ISO14443-A tags. The NFC Forum refers to these tags as Type 1, Type 2 and Type 4 tags. FIXME integrate this The Anti-Collision example describes the initialization messages used to set up a communication channel and to retrieve the identifier and supported features from a tag. During the anti-collision phase, three or four different frames are received from a tag (ATQA, UID, SAK and optional ATS).
The ATQA, SAK and ATS values can be used to identify the manufacturer, tag type and application. However, it’s not recommended to rely on ATQA due to potential collision when more than one target are in the field.
A recommended document to identify MIFARE tags: MIFARE Type Identification Procedure.
The following table shows a list of known tags and their anti-collision values (hexadecimal). Please contact us to help update and expand this list.

Protocol for smartcards is referred as T=CL and is basically the same as for T=1 (for contact smartcards).
