We just did some red team testing at one of our locations and this came up. Impeccable timing once again boys, cheers.

Has anyone recommended/used RFID Blocking Badge Holders that are designed to block low frequency 125kHz? This question is related to "digital pickpocketing" We all know you cannot block it 100% unless wrapped in foil or a lead box but by using RFID Blocking Holders you can reduce the ability to be compromised.
What are you doing to mitigate the risk while doing the obvious by getting rid of the vulnerability all together? When you have 250K Cardholders and over 10K Access Points replacing the vulnerability is not an easy task.

Last year we replaced our entire compliment of 10K prox cards with dual-format HID cards, then implemented a project to begin replacing readers the old prox readers with iClass units at +50 sites beginning with the perimeter, then main access points and critical doors. Also issued a directive to our security vendor that all new and replacement readers are to be iClass. Process is working pretty well; card replacement took 6mths and allowed us to updated all cardholder info (photos, security questions, PIN's etc). By having the cards compatible with both format readers, no disruptions to the end users. Side-note: if you include a PIN requirement with 125khz cards, doesn't matter if people have a clone (as long as people don't keep the PIN with the card).

Where did you get that particular writer? I want one to bring around with me to demo how easy it is. I could probably sell a lot of readers and cards once they see it.

People will always complain, but make the application reasonable, explain the whys and stick to a standard (don't make exceptions for specific sites).
The requirements has always been in place as part of our layering strategy, specifically at exterior doors outside of core business hours. This way you minimize the number of access points where they'd encounter delays (only 3sec per user/transaction) and only about 25% of staff are affected by the requirement.
Biggest challenge was sites deviated from the standard over the years, and people forgot their PIN's. Enter the new ID roll-out where we required people to pick a new PIN and made it part of the enrollment process (like when signing up for a credit card).
This also provided us an awareness opportunity to explain why PIN's are required.
20% of people will complain no matter what, 20% will tow the line no matter what, it's the middle 60% you need to try and win over and the only way to do that is with a good awareness and comm strategy.

there once was an RFID Copier app for phones that have NFC on the android appstre. does anyone remember the name? (around 2015)

Why would you add another reader to the door instead of just replacing the existing with a multiclass type reader. The multiclass reader will be a little more expensive than a standard high frequency but you will save more in the labor cost of just removing the old reader and replacing in the existing place, especially if you have a switch place style reader where the installation holes are standard.

For clarity, we didn't add a another reader, we replaced the existing. Because 125khz are easily compromised, I made the policy decision that LF prox cards are no longer acceptable for the corporation given the vulnerability. We replaced all cards with dual format and implemented a 5-yr refresh cycle, then replaced all readers to HF only. No impact to card holders but reduces exposure of the 125's. Going MC wouldn't have mitigated that risk. As for the plates, our installer fabricated plastic blanking plates (gloss, beveled edges) that matched the dimensions of the old readers, mounted these to the 2gang box (where required) and mounted the new readers to the surface. Looks clean, plates were about $2 per.
