Abstract
One or more detection activities of a card may allow calculation of rolling speed in motorized readers. Accordingly, the detection activity may result in a data transmission speed with greater accuracy after a determination of position, velocity and/or acceleration of the faster-moving device in relation to the card. Such detection activities may increase a probability of a successful communication sequence.
Claims4
A method, comprising:
- detecting a presence of a read-head housing of a magnetic stripe reader using a first detected capacitance change in a first pad during a first time period;
- detecting a type of said read-head housing of said magnetic stripe reader using a first detected inductance and a second detected inductance;
- detecting a second detected capacitance change in said first pad during a second time period;
- calculating a calculated data transmission speed based, at least in part, on said detecting a type of said read-head housing and said second detected capacitance change;
- and
- activating a communication sequence with said magnetic stripe reader in response, at least in part, to said calculated data transmission speed.
