It appears a rash of pin pad debit and credit card frauds in Saskatoon is continuing.

But police say it's getting harder for criminals to get your bank information, because local businesses are finally starting to be vigilant about the scam.

Police spokesperson Alyson Edwards sasy in two recent cases, potential scammers were caught in the act by employees.

"The acts were interrupted and the suspects fled. It is good to know that employees and businesses are being vigilant and they know a little bit more, perhaps, now about what to watch for."

In four other instances, businesses later noticed their pin pads had been swapped for fraudulent ones.

Restaraunts, fast food joints, retail stores and convienience stores have all been targeted.

Businesses should securely mount pin pads to the counter, label or engrave them so it's easy to spot if they're switched, and train employees to watch for sketchy behaviour.
