50 pcs 26 Bit Proximity CR80 Cards Weigand Prox Blank Printable Swipe Cards Compatable with ISOProx 1386 1326 H10301 format readers. Works with the vast majority of access control systems

cards come 10 in a sleeve and are individually packaged within the sleeve. they work great. the site code is on the bottom left and the card number is on the bottom right. arrived exactly as advertised. will buy again. thanks.

Work perfectly on maxiprox HID system, and only 1/6 the cost of HID prox cards. They also appear to be the same quality.

The vendor who installed our S2 security system wanted to charge us $10 per proximity card once we ran out. They later changed their quote to "only" $5 a card when we hesitated. At only about $2 a card, this purchase was a far better deal, and they work just fine. We use an Enduro 3E printer to print on both sides of these cards and the images look great. I appreciated the fact that we were able to order just a couple of cards from this vendor so we could test them before committing to purchasing more. The only thing that threw us a bit was the way the card number and site numbers were printed. In the examples shown on Amazon, the site number was in the lower left corner and the card number was in the lower right corner, but what we received had all of the numbersin the lower right corner with a space separating them. This caused our staff to think the whole thing was the card number and so we thought at first they didn't work, but once we figured out that only the last 5 digits were what we needed, all was good.

Exactly what we were looking for to use with our security system for our preschool. The parents use the cards to unlock the door and we printed bar codes on the cards for check in/check out. Works great, quick shipping, decent price!

Skinny card with marks for slotted hole punch both portrait and landscape. Printable if needed. It doesn't get any better than this, best bang for your buck.

EDIT: a different reader does show them as: HID H10301 26-Bit Indala 26-bit Proximity Weigand Prox / HID cards. However: Can't write to the cards / write error. Just the same as the flat smooth ones that come free with most card writers as demos. Had to order different product from another seller: amazon.com/dp/B0C2ZRFMW6 ASIN B0C2ZRFMW6 Not tested yet but look Clam Shell shape from videos. EDIT: these don't write either on 2 different writers.

Works great
