Abstract:
In a receiving method for the contactless reception of identification information (I1,12), which is stored in a data carrier (3, 3′) and which can be received from the data carrier (3, 3) in a contactless manner in the form of information units (IU, IU′) with a communication device (2), it is envisaged that firstly an information unit (R.IU) is received and that secondly it is detected that the received information unit (R.IU) represents a collision of two different information units (IU, IU′) occurring essentially simultaneously, of which two different information units (IU, IU′) the one information unit (IU) originates from a first data carrier (3) and the other information unit (IU′) originates from a second data carrier (3′), and that thirdly a received information unit (R.IU) that represents a collision is replaced with a first replacement information unit (R.IU1) established by the communication device (2), which is used instead of the information unit (R.IU) representing the collision, as the information unit (IU) that originates from the first data carrier (3), and that fourthly, the first replacement information unit (R.IU1) is delivered in a contactless manner.
