Printing & Encoding

atlasRFIDstore offers custom encoding as an additional service for all of the RFID tags available for purchase.

Why Custom Encoding?


RFID tags generally come from the manufacturer without unique IDs written onto the integrated circuit. Although some tags do come with sequential unique IDs, they are frequently not in the end user's desired format. Because RFID tags are usually used to identify specific assets/people/entities, most RFID tags need to be encoded with data before they can be used. This is where atlasRFIDstore comes in.



Custom RFID printing always goes through a quoting and approval process, but a high level overview of our capabilities includes:

  • Encoding RFID tags with your preferred data.
  • Printing/Encoding Barcodes to label your tags.
  • Printing Images on your tags.
  • Expedited Fulfillment is available.

Lead Time:


Lead time varies greatly depending on Volume and the requested Printing/Encoding options. Filling out our Quote Form below is the best way to find out lead time.  

How To Buy:


The best way to inquire about Custom Encoding is by filling out the form below. After you fill out the form, a sales representative will reach out to you within a business day or sooner.

What data will be encoded to my RFID Tags?


If you purchase custom printing and encoding, the atlasRFIDstore operations team will encode 24 digits of hexadecimal characters to the RFID tag’s EPC memory. Specifically, the sequence will begin like this:


That number will be augmented sequentially up to the number of tags that you purchased. So, if you purchased 5000 tags, your sequence will begin and end like this:

000000000000000000000001 - 000000000000000000005000

This will result in each tag having a unique identifier that you can use in your RFID application.

If you have other specifications for the tag’s EPC memory that you would like to have encoded, we will be contacting you after you purchase your tags. Our sales team will ask you for a spreadsheet of the data that you would like to have encoded. If you do not specify a different set of EPC data, we will use the sequence mentioned above.

What human readable data will be printed on the tags?


By default, the atlasRFIDstore operations team will print your tags with human readable data that matches the tag’s EPC so that you don’t have to use a RFID reader to read each tag when you are applying them. The data series will begin with 1 and run sequentially up to the number of tags you purchased. Unlike the tag’s EPC data, we will not print leading zeros on the human readable portion of the tag.

If you have other specifications for the tag’s human readable portion, we will be reaching out to you after you purchase your tags. Please tell us about these requirements when we contact you. Our operations team can offer the following options:

  • Barcodes (almost any standard)
  • Black and White Labels
  • Other text (as tag space allows)

Will all of the RFID Tags that I purchase be encoded?


If it is vital to your application that your tags be delivered in a complete and perfect EPC memory sequence, please let our sales team know. Frequently, calibration issues create “skips” in the tag sequence that result in the sequence stretching over the number of tags that customers purchase. For example, instead of a sequence from 1-5000, a sequence might run from 1-5005 because 5 tags were “skipped” in the printing process due to voided tags.

We can ensure that a roll is perfectly sequential, but we need to know that this is important to your application before we begin the printing process. Most applications only require that tags have unique identifiers, so this does not cause end user issues.

What are the RFID tags with BLACK DOTS?


Most manufacturers have a stringent quality assurance process that checks each tag’s EPC memory. When a roll is found with a defective RFID tag, a black dot or marking is placed on the tag to let the end user know that they should not use that tag. Subsequently, an additional good RFID tag is added onto the end of the roll to ensure that you receive the full purchased quantity of tags.

When we print/encode RFID tags, our printer should automatically identify the defective RFID tags and print “VOID” on that tag. Furthermore, the sequence should continue unbroken. However, sometimes our printer’s quality assurance standards are not as fine-tuned as the manufacturer’s. This means that we sometimes print and encode these black mark tags. We recommend that you DO NOT use the black mark tags even if they are not marked VOID. Again, this means that the sequence may have some “skips” because a bad tag was used as a part of the sequence. Let us know if this “skip” will have a negative effect on your RFID deployment.

Can I lock my tag’s EPC Data or encode different portions of the tag’s memory?


UHF Class 1 Gen 2 RFID tags frequently have different sections of memory to which data can be encoded. Our service bureau can work with you to (1) password protect (lock or permanently lock) your tag’s EPC from changes (2) Encode to different portions of memory on the tag including the tag’s EPC or User Memory sections. This may be associated with additional costs, but reach out to us if you have any questions about using different portions of your tag’s memory.
