How quickly do you ship tags ?

Seritag usually have over a million NFC tags in stock ready for customer jobs and hundreds of thousands available for immediate shipment. We aim to get most orders, including encoding orders, out within 24 hours.

Can I pay by bank transfer ?

Yes. You can place your order online as you would by credit card and at the payment page just choose pay by bank transfer. All the order details are stored. If you need a pro-forma invoice to enable payment, then we can provide this for you from the information you provide.

Which tag will be best for my application ?

Seritag sell a limited selection of NFC tags. Each tag is selected for a specific purpose and you can find some more information on our NFC tag selection page.

Can you quote in US dollars ?

We can. We can typically quote a 90 day fixed written USD price for any product that you see on the website. Just contact us with your requirements and we can provide the quotation for you.

Do you sell encoding or ID printing machines ?

We don't. The machines are extremely complicated and carefully calibrated to run very quickly and accurately. Unlike some NFC suppliers who simply bolt together various parts and hope for the best, our machines are designed from the ground up specifically for the job. We don't have the ability to support providing the machines to others.

How long does it take to encode NFC tags ?

A lot depends on the job being processed. Our machines are capable of tens of thousands of tags per hour. However, Seritag take a strictly accuracy first, speed second approach. We will schedule or slow down a job to ensure 100% accuracy rather than trying to rush it through and make mistakes. That might, for example, mean splitting a job between multiple encoding machines. If you are on a tight deadline, then speak to us. We don't make promises we can't keep and will usually be able to suggest a solution such as batch deliveries, alternative tags, direct shipments or whatever can help.

As a general rule, unless you are ordering over 100,000 tags or have a very complex order, adding encoding is very unlikely to delay your tag shipment.

Can you encode tags that I supply ?

We can't. Our encoding and ID print machines are tuned for specific tags. We know that it is never cost effective to attempt to use other tags.

Can Seritag produce full colour custom printed tags ?

Yes. We have a vast amount of experience manufacturing and supplying printed NFC labels. There's a large number of options which is why we don't offer them online. Speak with us and we can advise you on the best and most cost-effective option.

Can Seritag supply NFC products such as wristbands ?

We have a single focus on NFC tags and we don't supply products such as wristbands or keyfobs.

Do Seritag carry all tags in stock ?

One the great benefits of a small product collection is that we can carry a large number of our tags in stock. However, we also sell a large number of tags ! This means that stock levels can vary quickly and a full stock at the start of the day can be gone by the end. If you have a project in the pipeline, just speak to us. We'll give straightforward advice on availability and do what we can to help.

Are there any NFC tags suitable for metal surfaces ?

Yes. We currently stock a very high quality 29mm on-metal NTAG213 label and an Industrial On-metal NFC Tag for use on both metal and non-metal surfaces. The label is supplied on a reel and has a white plastic face which can be ID printed, QR code printed and encoding quickly. Please note that our stock levels change quickly on these products so please contact us if you have a large product in the pipeline.

Can you ship tags anywhere in the world ?

We can ship NFC tags to most countries worldwide however online ordering is only currently available for our European customers. If you are outside the EU, then please just contact us and we can provide shipping times and costs.

Can you encode data other than a web address ?

We can technically encode anything onto the tags. Anything other than a web address means that we usually either require a sample encoded tag from you or we will encode and ship you a sample tag for testing. We have extensive experience with encoding and this is the best and most reliable way to encode anything other than a web address. It works and it causes no problems. However, it does mean that at present, the order needs to be placed offline.

Are the tags unique ID's always unique ?

Yes and no. Technically the UID is unique but it depends on your application whether you should rely on it. There are both fake chips on the market and also chips that allow the UID to be encoded. This means that a UID can be duplicated. In short, for high security applications, you should not rely on the UID. On the flip side, you won't find any fake chips with Seritag and that means any tags we supply to you will have a unique ID.

Are some NFC tags more secure than others ?

Yes. The NTAG213 chip has a password protection feature which can 'hide' some of the data on the chip. However, we also often stock even more secure chips such as NXP's new NTAG413 or NTAG424 DNA chips which can create a special unique code with each scan. Note that that the 413 and 424 chips are specialist products which require advanced encoding and software to function.

Why do Seritag only stock SMARTRAC and SAG tags ?

Seritag work with a very limited number of tag manufacturers. We have tried and tested tags from almost every manufacturer in the world. However, when it comes to reliability of product, manufacturing tolerances, peel consistency, scan consistency, long term reliability, quality control and a whole range of other essential criteria, there's only a handful of manufacturers that are worth working with. We only currently stock and sell SMARTRAC and SAG tags online but if you are looking for a specialist tag or a slightly different size then talk to us.

Why are quality tags important ?

If you are using NFC tags in your application and reliability is not an issue and few pence/cents is - then you can save money. However, we've come across very, very few applications where both short term and long term reliability isn't worth the small amount extra. Therefore, Seritag only work with the best tags on the market.

Can the ID print be in different colours ?

Technically yes, but we don't recommend it. Seritag use a very specific (and expensive!) resin based ink for ID printing. Resin based inks have enhanced scratch, heat, chemical and other resistance. We have to print slower, but it's worth it for the increased quality. Many of the colours use a resin/wax or wax based ink which means an inferior print. We know some of our competitors can offer this but they don't have the quality standards that we do !

Why do the tags mostly have NTAG213 or NTAG210µ chips ?

NXP's NTAG213 chip is the most popular NFC chip for use with NFC tags and mobile phones. It's full featured and has more than enough memory for most applications and web addresses. Therefore, the costs associated with mass production of this chip and tags with this chip mean that it's a great value chip. The NTAG210µ chip has very few features and limited memory but if all you need is a simple short web address and the best price, it's a perfect choice.
