Pros and cons
Pros
- Monthly fee of £0 on the personal account, so holding the account costs nothing to maintain.
- Currency conversion fee of 0%, so foreign spending carries no markup beyond the exchange rate itself.
- A mastercard card, so it is accepted wherever cards on that scheme are taken, at home and away.
- Built for business, student and kids money: business, student and kids.
- Lists multi-currency and travel features: multi currency and travel, which suit money held in more than one currency.
Cons
- Support runs on help centre only, so there is no phone line or live chat to reach and questions are handled in writing.
- It is a prepaid card, so the balance has to be loaded before it is spent rather than drawn from a current account.
- It runs on mastercard while Visa is the network most listed brands use (58.6%), so a reader whose other cards sit on Visa would need to check acceptance in the shops and machines they use.
Who it suits
- Readers who want a prepaid card with a monthly fee of £0 and a conversion fee of 0%, and nothing recurring to budget for.
- Business, student and kids money: business, student and kids is the audience the listing names.
- Anyone spending in more than one currency, since multi-currency and travel are the features listed: multi currency and travel.
Who should look elsewhere
- Readers after a single-market card: HyperJar is built around multi-currency use (multi currency and travel), while JMMB Moneyline and JMMB Money Transfer prepaid card quotes a monthly fee of JMD 0 in Jamaican dollars and CrediMax Cardy EX prepaid Visa BHD 0 in Bahraini dinars.
- Readers who want a Visa card rather than mastercard: CrediMax Cardy EX prepaid Visa runs on Visa with a monthly fee of BHD 0, where HyperJar runs on mastercard at £0 a month.
Using it abroad
HyperJar's currency conversion fee is 0%, so a foreign purchase is not marked up on top of the exchange rate applied to the card. The card runs on mastercard, so it is accepted wherever cards on that scheme are taken, which keeps the acceptance pattern familiar for readers who already hold a card on it. For a trip, or for regular spending with sellers in other currencies, a mastercard card paired with a 0% conversion fee removes the cost that usually settles the choice.
Fees and currency costs
The costs that matter for this account both sit at the floor: the monthly fee is £0 on the personal account, and the currency conversion fee is 0%. A monthly charge of £0 means there is nothing recurring to set aside and no reason to close an unused account to save a fee. The conversion fee decides the running cost for anyone who spends away from home, and at 0% it takes nothing extra. Between them, the published pricing on the personal account is £0 a month and 0% on every foreign purchase.
Where it sits among rivals
On the fees that decide most comparisons, HyperJar sits at position 1 of 419 brands for the monthly fee and position 1 of 259 for the currency conversion fee. The monthly fee ranking is drawn from 419 brands and the conversion fee ranking from 259, so both placements come from fields large enough to carry weight rather than short lists. A reader weighing cost above everything else has little left to compare here, while a reader weighing other things is looking at a card priced in the cheapest band on both of the fees they will check first.
Using it day to day
The card is a prepaid card, so the balance is loaded before it is spent rather than drawn from a current account, which suits keeping a child's or a small business's spending bounded. It runs on mastercard, so it is accepted at the shops and cash machines that take that scheme. Support is the thinner part of the setup: help runs on help centre only, with no phone line or live chat listed, so questions are answered from written answers rather than picked up by a person. That suits readers who are comfortable reading before they ask, and it suits a shared family account less well.

Frequently asked questions
What does HyperJar cost to keep?+
The monthly fee is £0 on the personal account, so there is no recurring charge to budget for once the card is set up. The only other published cost is the currency conversion fee, at 0%, and it applies to any spend in a currency other than sterling. For a reader building a monthly budget, that means holding the account adds nothing to fixed outgoings.
Is there a fee for spending abroad?+
No. The currency conversion fee is 0%, so nothing is added on top of the exchange rate when the card is used in another currency. That percentage is where most prepaid cards take a cut, and here it is 0% as well, so a trip or a run of overseas purchases does not raise the bill on the currency side.
What kind of card is HyperJar?+
HyperJar is a prepaid card, which means money is loaded onto the account before it is spent rather than taken from a current account balance. That suits a reader who wants a hard limit on what a child or a small business can spend. It is less suited to anyone who wants the card to act as a plain bank card for the month's bills.
Which card network does HyperJar use?+
The card runs on mastercard. That decides where it works: it is accepted at the shops and cash machines that take cards on that scheme, both at home and abroad. For a reader who already holds a card on mastercard, acceptance abroad follows the same pattern, so one card can cover spending in more than one country.
How do I get help if something goes wrong?+
Support runs on help centre only, so help is written rather than spoken. That works for questions about fees, a blocked payment or how the account works. It suits a reader who is comfortable searching for the answer, and it suits a shared family account less well if you would rather pick up the phone about a problem on a child's card.
Who is HyperJar aimed at?+
The audience listing is business, student and kids, business, student and kids. In practice that points to money used for a small business's outgoings, a student's spending, or an amount set aside for a child, rather than a card opened for a single salary account. The multi-currency and travel features listed, multi currency and travel, add a reason to hold it when money sits in more than one currency.
How does HyperJar compare with other cards on price?+
On the fees a reader checks first, HyperJar ranks 1 of 419 brands for the monthly fee and 1 of 259 for the currency conversion fee. Those are large fields, so the placement carries weight, and it matches the figures on the account itself: £0 a month and 0% on conversion.
How does HyperJar compare with Skrill?+
Skrill's monthly fee is €5 against £0 for HyperJar, so the price difference sits in the monthly charge rather than in the currency conversion fee. A reader who wants a wallet with a stated recurring cost can weigh Skrill against this; a reader who wants nothing recurring to set aside and a 0% conversion fee has the cheaper card here.
