I'm surprised these PoS systems aren't managed with automatic updates, since the merchant service providers (along with the banks) are usually the ones losing money if they get hit with chargebacks.
- dfox 12y agoIn europe typical deployment solves this problem (EMV is quite orthogonal to this) by the fact that card data does not touch the PoS system itself. In fact any other approach is not feasible as PoS systems themselves are invariably horrible mess of accumulated kludges and backward compatibility restrictions. And there are quite powerful economic incentives to keep this state of things. Security-wise this is one of the few situations where semi-air-gapped network makes sense (for the PoS part, with card terminals having their separate network).
