Posting this as a separate suggestion as existing posts are for RMS. This is specifically for POS (not RMS): Suggest Microsoft work with their "recommended" mechant service providers to provide the capability to qualify credit card transactions with zip code verification. After reviewing the fees on my bill that my mechant services provider was charging, they recommended using zip code verification to reduce my charges/rates. MS technical support confirmed that MS POS does NOT support this feature. This puts MS POS as a disadvantage over competitve point of sale systems and causes a higher cost to those of us using it.
