The 1840-5084 is an RFID-blocking credit card sleeve that blocks radio frequency signals from reaching credentials stored inside. Constructed from tear-proof, water-resistant paper with embedded metallic shielding, each sleeve accepts standard credit-card-size inserts measuring 3.38" x 2.13" (86 x 54mm) within an outside sleeve dimension of 3.50" x 2.13" (89 x 54mm). The multi-directional opening allows cards to slide in from either end.

The embedded metallic barrier blocks RFID skimming attempts from electronic readers. Cards remain easy to access when needed while staying protected from unauthorized electronic reads when stored inside the sleeve. Simply slide the card out of the sleeve when you need it read by an authorized terminal, then return it to block all signals again.

Banks, financial institutions, government agencies, and corporate travel programs issue these sleeves to protect employee and customer credentials from electronic data theft in public spaces. Healthcare organizations use them to protect smart ID cards and access badges. IT security teams and loss prevention departments use them to protect RFID-enabled credit cards, CAC cards, and e-passports across large workforces. The blank exterior surface accommodates custom printing for organizations that want to add branding or usage instructions to the sleeve face. USA made and GSA approved.

Use as directed, when needed, and you'll be good to go.
A must have if you have a need for a ZDDP additive. This won't fix your worn valve seats, leaking piston rings, seasonal depression or gout but it will improve the lubricating properties of a quality oil in a properly maintained motor for your longevity goals.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.
