An urgent warning has been issued, and it could affect anyone who withdraws money at cash machines.
It follows after reports that scammers have been tampering with the machines in a bid to steal the money coming out.
Fraudsters are currently using dual-purpose cash machines to access withdrawals, as reported by Lancs Live.

Scammers have been covering the withdrawal slot with a plastic cover in an attempt to trick people into thinking there is only one box for both withdrawals and deposit
This leaves the customer thinking the cashpoint must be out of service since no money has been dispensed when in reality the money has been dispensed behind the hidden slot.

When the customer walks away, the fraudster can then approach the machine, open the cover over the correct dispenser and pockets the money.
In a video, customer Hasan Mahmood questions why his money was not dispensed.
He then discovers a sign above the ATM that says deposits are currently out of service.
The customer is led to assume the deposit box is the same box that cash is dispensed out of - which is currently out of order.
He then discovers a plastic lid on a separate part of the cash machine. He is seen peeling off the plastic cover where his cash can be found.
In the filmed clip, the customer used a Nationwide Building Society cashpoint, however other banks that include deposit boxes are likely to be affected.
The building society said customers should always check for suspicious activity before withdrawing cash in public.
A spokesperson said: “The type of incident highlighted in the video, although rare, can happen to ATMs anywhere at any time. Nationwide has a range of measures in place to try and combat these types of scams.
“However, as the video also demonstrates, it is important that people remain vigilant and check for any suspicious devices when using ATMs, especially those located outside.”
Several more lenders have issued warnings to customers in the wake of this.
Santander said customers should check for suspicious activity before entering their card or pin number.
“Using a cashpoint is easy, convenient and almost always safe. But sometimes criminals tamper with cash machines to steal your card information, PIN, or cash,” a spokeswoman said.
“Always be vigilant when using an ATM – lookout for any signs it might have been tampered with or damaged but also be aware of covering your PIN and ‘shoulder surfers’ hanging around.”
Barclays issued a similar warning, adding that spelling mistakes, such as in the warning sign above the ATM in the clip, should be considered a red flag.
“Our message is that if you see anything unusual or suspicious at an ATM, do not use it - report it immediately to the police or the nearest branch,” a statement said.
Industry body UK Finance said if your money does not come out, you should contact the ATM provider or lender immediately.
"Cash machines are generally very safe to use, with millions of transactions every day, but it's still important to take some simple steps when withdrawing money,” a statement said.
“If you notice anything suspicious or unusual about an ATM, such as signs of tampering, don't use it and if possible alert nearby staff or call the police.
“If no cash comes out or your card is jammed, report it immediately to your bank or building society, ideally by calling them while you are still in front of the machine.”
