关于居住证延期指纹采集的问题

我的居住证快到期了，然后在网上看的需要交F3表格。可以在网上交，但14天内要去移民局采集指纹和相片？我去年来的时候采集指纹了啊，怎么又要采集啊，有点搞不懂？
Please note that when you submit an online application, or if you send the application by post or e-mail, your biometric features must been recorded within 14 days of submitting application. You can have your biometric features recorded at the Danish Immigration Service's Citizen Service. If you live outside the Greater Copenhagen area, you can also have your biometric features recorded at a police station capable of recording biometric features.

那我网上交了不还是得去移民局一趟啊。
