Good concerns. One thing to add here is that often times in household HVAC system the thermostat relay doesn't handle the current for the heating/cooling element. Rather, it is the on/off relay for the main relay inside the h

Haha. Gotcha! Learned something new. :) When you said "a German thing" earlier I thought you meant there is a specific standard for Germany called EMV. I was so confused.
304.
by bravo22 12y ago
Haha. Those are EM C tests, not EM V . I've never heard anyone refer to it as EMV. Is this perhaps a German language thing? Does E lectro M agnetic C ompatibility translate to EMV in German?! EMV is Euro-Mastercard-Visa. :)

I am fully aware of CE and FCC. As a hardware engineer I've had to obtain those for a number of products myself. Could you please point me to EMV for Germany? I've never heard of it before and am fairly certain CE covers Germany a

Question -- why does your campaign involve "EMV" & FCC certification? Do you mean CE?!

You are correct. However, Trusted Computing crypto is different than the crypto accelerators you find as peripherals in an SoC. I should have been more clear that I meant crypto peripherals. There are crypto instruction extensions but don&#

by bravo22 12y ago
I don't think it is that. ARM doesn't make the crypto. The SoC makers put their own crypto cores so it wouldn't help ARM that way. I think just like they bought Keil (a dev tools maker) this is a strategy play to make it eas

My theory is that FBI is providing cities with some of these technologies as a sort of dog fooding. To iron out the kinks in their tracking technology. It does seem over kill to use something like that for a robbery, in a city like Baltimor

Their first product was very similar to the deadbolt one but it was a retrofit electronics for someone else's mechanical deadbolt. It was also powered and had to be connected to Ethernet. I'm going by memory and could be a bit off

They're not working on it as something new. That was their first product many years ago.

... and the hardware can vary greatly from chipset to chipset and from phone to phone. There are a number of drivers that work directly with the underlying chip and hardware. You can never emulate that. The actual CPU (ARM, x86) is a small

True but the vast majority of Android developers don't need to use NDK. Additionally the native part can run as x86 code. It doesn't need to be emulated.

Android apps are Java based. Google does not need to do what you just said.

Those two don't seem to be the same thing. Tessel runs javascript on the micro so you can write your programs in js instead of C and compile it. What you've linked to is a js library for connecting to Spark cloud. Overall I think

Tooling? You mean software toolset or mechanical tooling?

Omissions and errors happen. Your company has responded better than most. I'm glad someone from your company was on the forum to correct the record. With respect to the tip flow, with Chip & PIN you would need the final amount befo

Interesting to see Osama Bedier listed as one of the people. He is the guy who ran PayPal's merchant terminal integration efforts, left for Google Wallet, and then left Wallet. I think there was a lawsuit filed against him and Google b

Well, here is my big question: WHY ARE YOU STORING CARD DATA AT ALL ? (sorry for the caps). You are a pass-through entity, merchant terminals do not store card data. They keep the authorization number from upstream provider to allow void&#

by bravo22 12y ago
If you are using magnetic strip you're correct. For PIN & chip the PIN is sent to the card and verified by the card and the resulting "signature" is sent to the bank. The card has to be in for PIN entry. An employee, abov

I appreciate you posting! I am not doubting that you are building the product. You/The company should probably put more effort in correcting the datasheet and the information you put out there. We can only judge by what is being presen

Interesting merchant terminal -- but it seems to be little more than a pretty rendering and physical mock-up right now. I like how the first guy puts his card in, takes it out AND THEN punches in his PIN, which is exactly how PIN & Chip

They change the PID to zero, which means Windows won't associate it with FTDI or any other driver. You have to jump through some manual hoops to undo it, which is something most people can't do. So for all intents and purposes it

I don't know about IBM channels. PCIe root has the ability to restrict transfer to a certain range and depending on system configuration there are remapping registers that translate between PCIe address and host memory address -- which

I agree with you regarding all of the above, except for the DMA bit. That has to do with crappy drivers causing crashes. Without direct DMA you'd have horrendous performance issues. It is not a transistor count issue. These days plugga

Thanks. I looked at more teardown pics. It is definitely a segmented display which is far easier to drive than an active matrix (i.e. "pixels"). They also don't have wireless and a host of other things that this device procla

From their paper: "We have observed variations between countries. While cards from Belgium and Estonia work like British cards, we have tested cards from Switzerland and Germany whose CVM lists specify either chip and signature or onli
