Create a new project, go in the "Contactless configuration" section then select the "Allowed baudrates in T=CL (ISO 1443-4" sub-section, click on the "Define configuration" button and unchek all the check boxes :

For a Prox'n'roll (not HSP)

Create a new project, go in the "T=CL speed limit" section then click on the "Define configuration" button and uncheck all the check boxes :

In both cases finish by pushing your configuration into the reader by using the "Project" menu then the "Write configuration into reader" option.

T=CL (ISO 15693)

This international standard defines the VCD/VICC communication scheme. It is divided into 3 layers: 1. Defines the hardware characteristics of the VICC, 2. Defines the carrier frequency and the bit-level communication scheme, 3. Defines the frame-level communication scheme, the session opening sequence (anti-collision/inventory), and the command set of the VICC. All VICCs are memory chips. Their data storage area is divided into blocks. The size of the blocks and the number of them depend on the VICC. Note that ISO 18000-3 mode 1 is the same as ISO 15693

T=CL (ISO 14443)

This international standard defines the PCD/PICC communication scheme. It is divided into 4 layers: 1. Defines the hardware characteristics of the PICC, 2. Defines the carrier frequency and the bit-level communication scheme, 3. Defines the frame-level communication scheme and the session opening sequence (anti-collision), 4. Defines the transport-level communication scheme (sometimes called “T=CL”). The application-level is out of the scope of ISO 14443. Most microprocessor-based PICCs implement ISO 7816-4 on top of ISO 14443-4. A lot of wired logic PICCs (NXP Mifare family, ST MicroElectronics ST/SR families, to name a few) implements only a subset of ISO 14443, and have their own set of functions on top of either ISO 14443-2 or ISO 14443-3. Note that ISO 14443-2 and ISO 14443-3 are divided into 2 protocols called 'A' and 'B'. A PCD shall implement both, but the PICCs implement only one of them1. Four communication baudrates are possible: 106 kbit/s is mandatory, higher baudrates (212, 424 or 848 kbit/s) are optional.

reader (Microprocessor-based card)

An ICC (or a PICC) whose chip is a small computer. This is the case of high-end cards used in payment, transport, eID/passports, access control... Key features are security, ability to store a large amount of data and to run an application inside the chip. Most of the time they implement the command set defined by ISO 7816-4.

reader (CD)

Coupling device or coupler. A device able to communicate with an ICC. This is what everybody calls a smartcard reader. Technically speaking it could be seen as a gateway between the computer and the card.

How to limit the communication with the card to 106kbit/s
