LEXI 100pcs Mi-Fare 1K S50 RFID Card, Rewritable UID Smart Card, Premium 13.56MHz PVC Blank Card for Door Access Control, Block 0 Sector

Good Product

Didn't work

As described and expected. I would buy again.This saves sooo much room. I transferred all my figures to these card and it makes it much easier to play with limited table space.YES these work for Skylanders.

so i bought this 100 pack. and i dont know, maybe 95-98 of them worked, with a few duds that were defective. so good enough, i guess.for me, I used them for skylander writing tags, and its handy that they come in some sort of plastic sleeve that i just had to cut with scissors. so i can print out a card and just slide it in there. 100 is plenty for me, because i was only missing 80 or so skylanders with variants.

bought a few batches of these, works great with UI Access Control system

The block zero is not rewritable meaning I cannot use them. They said in the name that they are but the ones I got aren't

Every thing as advertised. Mhz, rewritable, block size and sectors all correct for my batch. Used a dozen so far no problems or duds. Will use again if necessary.

If you use these in a badge printer, you will almost always get an imperfect print. This is because nearly EVERY card has a very subtle bump or divot which will cause most badge printers to leave a white spot there.
