Abstract
A contactless communication circuit (card) communicates with a proximity coupling device (reader). The card hosts at least two applications. The card initializes an identifier of a communication protocol to a first value. In response to a failure of a transaction with the reader, the card increments a counter. When the counter reaches a threshold, the card changes the identifier to a second value.
Claims22
A method, comprising:
- initializing, in a contactless communication circuit hosting at least two applications having different communication protocols, an identifier of a communication protocol to a first value;
- in response to a failure of a transaction between the contactless communication circuit and a proximity coupling device, incrementing a counter value in the contactless communication circuit;
- and
- when the counter value reaches a threshold, changing the value of the identifier to a second value.
1 more element
A device, comprising:
- one or more memories;
- and
- contactless communication circuitry coupled to the one or more memories, wherein the contactless communication circuitry, in operation:
- initializes an identifier of a communication protocol to a first value corresponding to a first hosted application;
- increments a counter value in response to a failure of a transaction between the contactless communication circuitry and a proximity coupling device;
- and
- changes the value of the identifier to a second value corresponding to a second hosted application in response to the counter value reaching a threshold.
4 more elements
A system, comprising:
- one or more circuits;
- and
- contactless communication circuitry coupled to the one or more circuits, wherein the contactless communication circuitry, in operation:
- initializes an identifier of a communication protocol to a first value corresponding to a first application hosted by the contactless communication circuitry;
- increments a counter value in response to a failure of a transaction between the contactless communication circuitry and a proximity coupling device;
- and
- changes the value of the identifier to a second value corresponding to a second application hosted by the contactless communication circuitry in response to the counter value reaching a threshold.
