Abstract
In accordance with a first aspect of the present disclosure, a transponder is provided, comprising: a field strength range determination unit configured to determine a field strength range of a radio frequency (RF) field generated by an external reader device; a controller configured to delay processing of a command by the transponder in dependence on the field strength range determined by the field strength range determination unit. In accordance with further aspects of the present disclosure, a corresponding method of operating a transponder is conceived, and a corresponding computer program is provided.
Claims20
A transponder, comprising:
- a field strength range determination unit configured to determine a field strength range of a radio frequency, RF, field generated by an external reader device, wherein the field strength range determination unit is configured to determine the field strength range by monitoring an activity of a clock-stop sensor comprised in said transponder, wherein said activity is an ON-time of the clock-stop sensor;
- a controller configured to delay processing of a command by the transponder in dependence on the ON-time of the clock-stop sensor as determined by the field strength range determination unit.
A method of operating a transponder, comprising:
- determining, by a field strength range determination unit comprised in said transponder, a field strength range of a radio frequency, RF, field generated by an external reader device, wherein the field strength range determination unit determines the field strength range by monitoring an activity of a clock-stop sensor comprised in said transponder, wherein said activity is an ON-time of the clock-stop sensor;
- delaying, by a controller comprised in said transponder, processing of a command by the transponder in dependence on the ON-time of the clock-stop sensor as determined by the field strength range determination unit.
