Open manualFrequently Answers and Questions
How do I select a single card from multiple cards in the field?
The ISO/IEC 14443-3 standard describes the card activation procedure, which involves polling for cards, sending a Request command (REQA or REQB) and performing an anti-collision process to identify and select a specific card.
What is the role of the anti-collision procedure?
The anti-collision procedure, mandatory for ISO/IEC 14443A compliant cards, ensures that only one card is selected, even if multiple cards are present in the reader field. It involves sending specific commands and analyzing the responses to resolve any collisions.
How do I select the correct application on a card?
After a card is activated, you need to select the correct application. This involves sending a Select command and checking the response to ensure it matches the desired application. The system must also handle the scenario where multiple cards with the relevant application are present.
Can I use multiple cards during a single transaction?
Yes, you can use multiple cards concurrently during a transaction by using the CID (Card Identifier) in the protocol. Each card is activated separately and addressed using a different CID.
What types of cards are supported by the ISO/IEC 14443 standard?
The ISO/IEC 14443 standard supports both Type A and Type B cards. Type A cards are commonly used for MIFARE products, while Type B cards are used in other contactless applications.
