Most modern scanners are universal. There was a specific brand of chip that Banfield was using for awhile that wouldn't show up on the first batch of universal scanners but I think either those chips kind of fell by the wayside or the newer universal scanners pick them up (can't remember off the top of my head). There was also a minor brouhaha several years ago over the chips that are required by the EU for travel being a different wavelength that wasn't read by our scanners (and ours not read by theirs) but again my understanding is that was sorted out and chips and scanners are pretty much universal at this point.
Some of the older universal scanners will only give you a number for a specific brand and say something like "brand X chip" or "chip detected" without a number, but even those do detect them.
