Magstripe working beyond 24-hour limit

I have been in the US for two weeks and in many places magstripe is the preferred method of dealing with cards. When using it for the first time it was rejected and I asked the cashier to wait a second until I enable it. I did.

But now the magstripe works all the time even though it’s disabled in the app. I didn’t mind it as I forgot to enable again and was in places where they didn’t have chip&pin nor contactless but I think it would be a good idea to check if everything is working correctly in that department.

Anybody else experienced the same?

The app enable for magstripe applies to ATMs only so use with merchants for face to face transactions should not be affected.

This was confirmed in Mayin this post:


Ouch that’s bad. Having the magstripe disabled is fairly important for security. Skimming is still a thing, even in the UK.

I mean I could just run a speaker magnet over it, but I might one day need it…

Not sure why it’s ‘bad’ per se. It’s Monzo taking this risk, not us. It’s a calculated risk. The toggle was only ever advertised to disable ATM use.

P.S. to clarify, Monzo is taking the risk of having to clean up the mess which costs time and therefore money. The actual transaction amount financial risk is borne by the merchants in, I believe, every region now (Israel was very recent but I think with Israel now being covered by a liability shift it’s every region).

Just to inform other people. Magstripe usage is not split between ATMs and transactions. Everything is covered by the manual switch you can find in the app.

I had one transaction declined in a shop and then my card froze even though it wasn’t an ATM and then was told by Customer Support that it’s because my magstripe is disabled…

If that’s the case then the description of the setting should be changed to reflect this.

I wholeheartedly agree. This magstripe business has been quite frustrating and confusing in general

This isn’t how it’s supposed to be work :thinking:

Magstripe should always work for shop payments. It should only need to be enabled for ATMs that require it.


Well there’s a lot of confusion about it. I haven’t used magstripe for weeks. Then one transaction - declined - card frozen… I haven’t used magstripe ATMs for a long time too
