Know when someone covers your code

Scammers paste their own codes over genuine ones on meters, tables and posters. Your code doesn't break; it just stops being scanned. That silence is what Kizmo watches for.

How it decides

  1. Learn the rhythm. For each code, Kizmo takes the typical scans for the same weekday over the past four weeks.
  2. Measure the surprise. It asks how likely today's count would be if nothing had changed, using a Poisson model of daily scans.
  3. Alert only when it matters. Zero scans with less than a 1% chance, or a collapse below a quarter of normal with less than 0.1%, raises an alert. Normal traffic closes it automatically.

Alerts that tell you where to look

Every code has a placement name. Alerts arrive by email and in your dashboard, naming the table, meter or poster. Customers can also report a code from its verify page, and you hear about it immediately.

“Table menu” at Table 7 stopped getting scans

It usually gets about 34 scans on a Saturday and got 0 in the last 24 hours. A sticker placed over a code is the most common cause.

Questions

How quickly will I find out?

Kizmo checks every monitored code daily and compares the last 24 hours with that code's usual scans for the same weekday. You hear about a silenced code within a day.

Will I get alerts when we're closed?

No, as long as you keep regular hours. Kizmo compares each day with the same weekday in previous weeks, so a café that closes on Mondays is expected to be quiet on Mondays.

What about codes that are rarely scanned?

Codes that average fewer than about four scans a day don't have enough signal for silence detection. Customer reports still reach you instantly.

Does an alert always mean fraud?

No. A code can go quiet because it fell off, was damaged, blocked by furniture or the venue changed. Every alert means: go and look.
