ListPassiveTarget(MaxTarget, TargetBaudRate) |
List all targets cards in range When using this function, you can't determine which target you've read So you'll need to use the Decode functions to try to get a card type So use this function only with a specific card type. Prefer the AutoPoll function As the type identified is returned |
