Bio-metric signature is differ than Passport signature?

[bipsan]

HI...
I have done my Bio-metric last week 10 Oct,
In my Bio-metric at the time of signature was small issue? we have to do signature with Digital pen and my signature is bit different than my passport signature and by the time I realise that, the women who was taking my bio-metric, said its done and saved and cant be change.

Now I m worried would be an issue? signature is bit different as digital pen was dropping touch pad.

Looking forward you,

Regds,
