A Em Card , TagId not equal the number print on the card ?

I have a card , and the card num is "0006635242" , I can read the number use another reader device , and show me the number "0006635242"。

But , when I use proxmark3 , I get the different result ,  "0a00653eea" ,  is there any equation between "0a00653eea" and "0006635242" ?

Done!

Auto-detected clock rate: 64
Thought we had a valid tag but failed at word 2 (i=23)

If you remove the first '0a' you have 0x00653eea, which is hexadecimal for 0006635242.
