    • Method for broadcasting a magnetic stripe data packet from an electronic card by measuring a swipe speed of the electronic card past a magnetic reader head during a swipe of the electronic card past the magnetic reader head and then adjusting a broadcast signal containing the magnetic stripe data packet according to the measured swipe speed so that the magnetic stripe data packet in the broadcast signal is read by the magnetic reader head during said swipe. The swipe speed is measured by a speed sensor such as a capacitive sensor having an outer detection point and an inner detection point. The electronic card can contain a false swipe detection means so that the capacitive sensor changes from a sleep mode to an active mode after a wake up sensor (such as a trip switch preferably having two or more conducting pads raised up from a printed circuit board by at least one spacer) is activated during the swipe and the swipe speed is measured by the capacitive sensor while it is in the active mode before the broadcast signal is broadcast during the swipe.
    • 一种用于通过在电子卡通过磁读取器头部的滑动期间测量电子卡通过磁性读取头的滑动速度然后调整包含磁条数据分组的广播信号来从电子卡广播磁条数据分组的方法 根据测量的滑动速度,使得在所述滑动期间,磁性读取头读取广播信号中的磁条数据分组。 滑动速度由诸如具有外部检测点和内部检测点的电容式传感器之类的速度传感器来测量。 电子卡可以包含错误的刷卡检测装置,使得电容式传感器在唤醒传感器(例如跳闸开关优选地具有两个或更多个导电焊盘从印刷电路板通过 至少一个间隔物)在滑动期间被激活,并且在滑动期间广播信号广播之前,电容传感器处于活动模式时测量滑动速度。
